The Value of Sophisticated Welding Jigs

One of the traditional welder’s most closely guarded secrets is his jig. Often custom made, it is key to both bending metal and cutting and connecting all the pieces required for any kind of project, big or small. But technology has taken over, and the contemporary welder has the advantage of being able to use the most sophisticated welding jigs, clamps, stops, angles and support elements available today.

Leading manufacturer and supplier of sophisticated welding jigs, Forster America has a wide range of unique fixtures, tools, and accessories that are designed for use with their cutting-edge welding equipment including modular welding tables, frame welding fixtures, rail and fence railing fixtures, and lift, turn and tilt welding tables. These make the old-fashioned welding jigs, made for purpose by welders, redundant.

The value of these sophisticated welding jigs, tools, fixtures, and accessories is that they enable welders to accommodate workpieces of different shapes and sizes, and they can be used to create unique solutions for all their welding needs. They also enable welders to work faster, more easily, and with ultimate accuracy.

Equipment Sets

Welding jigs are essentially tools or devices that are used to hold components in place for cutting and welding. Forster’s range of equipment sets do this and more.

For example, sophisticated equipment sets for stainless steel rack and case manufacturing contain absolutely everything a welder in this industry niche needs including:

  • Clamping arms, clamping columns and clamping towers
  • Adjustable flat clamps and flat stops
  • Aluminum try-squares of various sizes
  • Right-angled brackets and support arms
  • Double slot profiles each with two screws and two T-nuts for assembling on a try-square
  • A continuously adjustable angle and universal angles

There are also very similar equipment sets for rack and case manufacturing with other metal materials that contain the same kinds and numbers of tools and accessories.

Equipment sets for manufacturing stainless steel frames are also similar. They come with a number of bronze-pad clamping arms, flat chromed steel clamps, and precision steel clamping columns, aluminum-finish universal angles, and flat stops, try-squares, edge angles, and quick release clamps, all made of aluminum.

Equipment sets for manufacturing frames made of other types of metal contain everything required for this type of welding including flat clamps, clamping arms and columns, flat clamps and stops, try-squares, edges and universal angles, and quick release clamps with flat stops.

Equipment sets for both stainless steel universal manufacturing and for universal manufacturing using other metals.  Both containing multiple clamps, stops, supports, try-squares, and other items.

Equipment sets for stainless steel tube manufacturing that contain all the tools and fixtures needed for successful stainless steel tube manufacturing. Like the other jigs and equipment sets, these work exceptionally well with Forster’s 3D welding systems and are uniquely versatile.

Equipment sets for tube manufacturing using metals other than stainless steel, also with the full range of tools and other equipment.

A wide variety of clamping elements, as well as angles, support elements, and clamping columns and clamping arms, are available separately, enabling welders to access every part of their welding tables without any effort.

When to Choose Aluminum Alloy or Gray Cast Iron Welding Tables Instead of Carbon Steel

Welding jobs involve the use of various types of metal and a number of different processes. While traditional welding tables were made of carbon steel, specialty welding tables are made of other metals including gray cast iron and various alloys that enable welders to achieve a professional finish.

The question though is, Which type of welding table should you use for specific projects?

Benefits of Gray Cast Iron Welding Tables

There are various types of cast iron all of which are alloys of iron, carbon (usually between 1.7 and 4.5 percent), and silicon.

Gray (or grey) iron is the most common form of cast iron. Also known as flake graphite because it contains many graphite flakes as well as perlite, it does not have good mechanical properties, and it is not an easy metal to weld using the metal arc-welding process unless the metal is preheated and the welding heat is controlled very carefully. It also has very low ductability and a low expansion point when the metal is exposed to any kind of heat.

The irony of this is that gray cast iron makes a really great surface for welding because the surface remains flat and welding spatter doesn’t stick to it. Since most welding processes result in some degree of spatter, it is an advantage to work on a welding table that is resistant to spatter.

As it ages, gray cast iron becomes increasingly resistant to the hot, molten bits of metal that spatter onto the work table surface during the welding process.

Benefits of Aluminum-Copper Alloy Welding Tables

When welding with stainless steel the best results will be produced by working on non-ferritic surfaces that do not contain iron. Ferrous metal surfaces can result in scratches to the stainless steel work piece and sometimes even more severe pitting.

By separating a stainless steel work piece from any type of ferritic material you are already well on the way towards a more professional finish. An aluminum-copper (AL/Cu) alloy surface has a high tensile strength, but this is combined with low surface hardness and high thermal conductivity which is also ideal in terms of spatter-resistance.

What Else Makes a Great Welding Table?

While the metal used for a welding table is hugely important, so too is the design of the table itself.

Foster America specializes in modular 3D welding tables that can be adjusted to accommodate a variety of components that can be used to create custom solutions for welding. The most exciting concept is so simple you’ll be pinching yourself, wondering why other systems don’t offer the same options. Forster America tables have rails that are spaced 100 mm apart and can be moved to accommodate jigs and other fixtures. This helps immensely during all those initial processes like measuring dimensions and angles, and is invaluable when you have to correct, re-align, and mechanically rework sections.

If you want something really great that offers a completely custom solution for your welding operation, call Forster America to see how we can help.

 

Save on Clean Up Time With Spatter Resistant Welding Tables

When people weld, lots of tiny molten particles of metal are blown away from the welding arc, often settling on the surface of the parent metal and the worktop of the welding table. It stands to reason, therefore, that having a welding table with a top that is resistant to spatter will save time on clean up.

Welding and Spatter

While some spatter is inevitable during most forms of metal arc welding if there is a lot of spatter this is usually due to poor welding conditions or the use of incorrect techniques. It is essential to keep spatter to a minimum because it reduces the efficiency of the electrodes used as a filler material while welding. It can also burn the person welding and his or her clothing. Additionally, weld spatter can cause imperfections on a work piece (or parent metal) and it will inevitably affect the appearance of the finished weld. It can also make a mess on any worktop. While spatter can be removed with relative ease, it can be a time-consuming exercise that adversely affects production time and increases the costs of welding.

Electrodes vary in type and form depending on the type of welding process used and metal being welded. Some types of welding processes (for instance those used for ordinary shielded metal arc welding [SMAW], which is also known as manual metal arc [MMA] welding) form a slag cover that protects the hot, molten weld metal from the air during the welding process. SMAW welding is also known as stick welding because the electrode is basically a solid round wire stick that is coated with flux and other components. The metal inert gas [MIG] welding process uses a continuous bare electrode on a roll that fits into the welding machine (welder). The electrode combines with a shielding gas that protects the weld from the air and does not produce slag.

Gas metal arc welding [GMAW] doesn’t generally produce spatter. When it does it is usually caused by incorrect welding parameters, using the wrong shielding gas, and bad technique.

Spatter Resistant Welding Tables

Forster America specializes in top quality welding tables that incorporate tops that are resistant to spatter. This negates the need for extensive cleaning after welding, saving time and money.

There are two primary products to choose from. The:

  1. Special grey cast iron welding table
  2. Welding table with an aluminum-copper (Al/Cu) alloy or carbon steel surface

Grey cast iron welding tables are highly resistant to spatter, especially once the surface has aged a while. As the metal ages, the carbon (graphite) moves to the surface, which becomes increasingly darker in color. Until this process is complete, a penetrating anti-stick coating may be applied to the tabletop to prevent any spatter from sticking.

Another advantage of grey cast iron includes the fact that it doesn’t expand much when exposed to heat.

The welding tables with Al/Cu alloy and carbon steel tops follow the same design that features T-slots. This accommodates a clamping system that avoids contact with ferritic material, avoiding unnecessary scratches, which is particularly beneficial when working with high quality stainless steel.

The T-slot system is particularly useful when welding casings and containers because it allows the work piece to be positioned freely through the slots from every angle. Positioning through the T-slots also protects the table and work piece from spatter.

Why Other Welding Tables Pale in Comparison to Forster America’s

The world’s best welding tables enable what was previously considered the impossible. Ultimately, with the right table it is possible to weld anything perfectly with absolute precision, however complex the design may be.

But what makes one particular welding table better than anything else that is currently available on the market?

Features That Determine the World’s Best Welding Tables

Different welding jobs have different demands. Some are quite routine and relatively simple while others are highly complex and complicated. Historically this has meant that companies offering welding services have had to ensure that there are multiple welding tables or a number of different welding stations that can cope with work pieces of different sizes as well as different metals.

Forster America has a range of the world’s most innovative welding tables that can cope with an impressive range of customer-specific solutions. These include welding tables that:

  • Are designed to streamline every possible operation
  • Swivel and tilt to 45 degrees
  • Are infinitely adjustable in height
  • That are designed to ensure that anyone using them is able to retain a good posture while working

What Forster America Tables Can Do That Others Can’t

4500 Frame Welding Fixture
4500 Frame Welding Fixture

Other companies offer fixtures for precision welding and machining, as well as assembly. Some of these are modular. Some have come up with mobile stations that can be moved around and used with turnkey fixturing kits.

A few, like Forster America have identified the need for affordable modular welding tables that will enable those using them to increase productivity and also improve their quality of work.

Various plate and/or hole and slot systems have been identified as a great solution for quality and flexibility. So too has the need for good accessories including clamps, pliers, magnets, and machine parts like threaded fasteners and levers.

Foster America’s products take all of these solutions a step further.

Even the most basic modular 3D welding table can be adjusted so that various innovative components can be used for custom solutions. For instance, Forster’s 3D grey cast and aluminum copper alloy welding tables can be used with a range of lift and horizontal rotary tables, as well as vertical turntables. They range in size from 39 in x 47 in to 118 in x 59 in and may be adjusted in height from 33 in to 37 in.

If that’s not a good enough solution, Forster America offers swiveling or lifting and tilting welding tables that can achieve what no other welding tables can achieve.

The company’s swiveling welding tables are ideal for use with jigs and can be used for 360 degree welding projects. So whether you need to work on the top or bottom of the work piece (from the top or underneath), this table will get you there. Those that lift and tilt can be adjusted to any degree or height. These particular tables and devices work using hydraulics and so are ideal for ergonomic welding.

Additionally, Forster America has a wide range of jigs and fixtures, manipulators and positioners, and 3D clamping sets all of which can be used with their superior welding tables. You won’t find them anywhere else.

Why Use a Welding Table That Swivels and Tilts

Whether you are a professional welder or someone who does welding projects as a hobby, why would you use a welding table that swivels and tilts rather than a traditional table that has a solid, horizontal surface?

If you can’t think of a suitable answer, think of the difference between a hard wooden chair and an ergonomic office chair that can be adjusted up, down, backward, and forwards.

The wooden chair might work if you sit nice and straight and don’t mind your bottom getting sore. The ergonomic office chair though is likely to help you sit correctly and also feel comfortable. The problem is that if the chair causes you to bend, stoop, or take up positions that impact on your spine you’re likely to be in trouble. At best this bad posture will cause discomfort, at worst it could cause skeletal injury. This might sound like over-kill, but it isn’t. The vast majority of people do not realize the impact of poor posture.

If a welding table can swivel and tilt, it stands to reason that it will make it a lot easier for the person welding to get to joints whether they are above or under the work piece. Instead of the welder having to bend awkwardly to get to inaccessible points, all he does is move the table to suit his needs. The added advantage is that it also prevents unnecessary downtime:

  1. Because the welder can work more efficiently and therefore is less likely to have to re-measure, make corrections, and mechanically rework the materials to get the job right.
  2. Bad posture can cause serious health issues that inevitably lead to absenteeism. This can impact on both the timeframe of a job as well as costs as other workers may need to be called in to complete the job for the absent employee.

Welding Tables

Lifting and Tilting Table

Traditional welding tables are flat and made of mild steel. Nowadays welding tables are still made from mild steel, but more specialized designs are made from cast iron, stainless steel, and from various alloys. You don’t have to compromise; you can choose exactly the surface that is best for the work you are welding.

Similarly, welding tables are traditionally just tables with four legs and an upper surface that is both horizontal and level. Jobs are done in parts, and a wide variety of clamps are used to keep the metal in place while the welding operation is in progress.

In recent years, welding tables have taken a totally new design turn with modular tables enabling work to be done much more quickly and efficiently. The most exciting element of these tables is that they can be adjusted to any position for precision welding that requires 100 percent accuracy of all measurements, angles, and alignment of parts. Additionally, all you need are a few standard components made for use with the tale and you can create a custom solution for any welding job you could imagine. These include lift tables, vertical turntables, and horizontal rotary tables.

Modular 3D Welding Tables

Modular 3D welding tables from Forster America are designed to enable welders to achieve custom solutions for any welding jobs. Instead of solid upper surfaces, their tables feature rails that can be adjusted to accommodate jigs and other fixtures. Made from gray, non-ferric cast iron or an aluminum copper alloy, the rails may be spaced up to 100 mm apart. Furthermore, each rail is able to withstand a maximum load of 1.5 tons if cast iron and 1 ton if made from the alloy. The most common width of Forster’s modular tables is 47 inches and the available length ranges from 39 inches to 118 inches. The largest table measures 118 inches x 59 inches.

Welding Tables That Swivel

The company’s swiveling welding tables are operated by electric motors and have a swivel range of 360 degrees. Like the 3D tables described above, they have slatted surfaces to accommodate jigs and other specialized welding tools. They also incorporate a valuable lifting function.

The prime feature of the Forster swivel welding tables enables the adjustment of axis using the center-of-gravity. A patented feature, because of gravitational force it enables the torque to be set to zero even when the welding is working with heavy parts that weigh up to one ton. The table is then secured in position simply and easily using a locking brake.

Welding Tables That Lift and Tilt

Designed to make the welding operation more efficient and productive, Forster’s lifting and tilting welding tables may be adjusted hydraulically to any height and degree. There are several different types that have been designed for different needs depending on whether it needs to lift and turn, lift and rotate, lift and tilt, or just lift.

Convinced that you should be using a welding table that swivels and tilts? Contact the friendly professionals at Forster America for more information.

Ergofix is Key for Welders to Maintain Good Posture

Bad posture impacts on our bodies and causes all kinds of problems, from muscular and back pain to fatigue. When it is constant, bad posture can cause chronic health problems because it impacts on the spine and can constrict nerves and blood vessels.

Good posture enables us to sit, lie, stand, and walk in positions that don’t strain supporting muscles or ligaments, particularly during activities that involve movement. This is largely because good posture reduces stress on the spinal column and allows our muscles to work efficiently. This, in turn, prevents muscle strain and helps to keep our joints properly aligned.

While welders are not the only people who are prone to bad posture, the fact that they typically bend forward over their work for prolonged periods of time makes them more likely to suffer back pain and injury to postural muscles. Those who are obese are even more at risk.

While there are proven ways to sit and stand properly to help maintain correct posture, people who have to lean over their work risk bending the spinal column. If you sit at a desk you can control your sitting position. When you stand and walk, you can do the same. But moving and bending in an unnatural fashion really can be damaging.

In some industries, particularly those that employ people who sit at desks all day, ergonomic chairs can be part of the solution. For welders, a height-adjustable welding table that can be rotated and tilted is the best solution for maintaining an ergonomic posture while working.

Ergofix – An Ergonomic Solution for Welding

Forster America has a height-adjustable welding table solution for bad posture in the welding environment. Recognizing that good posture is virtually impossible with regular non-adjustable welding tables, the company now manufactures Ergofix, a state-of-the-art welding “manipulator” that is infinitely adjustable in height. Better still, it can be rotated a full 360 degrees and tilted up to 45 degrees.

Ultimately, the Ergofix welding manipulator enables welders to maintain good posture while they work. This is not only the best solution for good health, but it also produces the best welding results because workers don’t get tired and sore.

The concept is brilliant, yet so simple, utilizing hydraulics to adjust the height of the tabletop from 27.2 inches to 39 inches. The rotation facility has continuous locking for ease of operation and accuracy.

Forster America currently offers three models with different dimensions:

  • Ergofix 800 – 31.5 x 31.5 inches
  • Ergofix 1000 – 39.4 x 39.4 inches
  • Ergofix 1200 – 39.4 x 47.2 inches

Like all Forster America welding tables, the Ergofix incorporates neatly spaced rails that can be adjusted for jigs and clamps, including the unique Vacufix clamping system. This enables welders to fix sheet metal parts securely to the table and work piece using a vacuum plate that has a very small vacuum surface. Welding seams aren’t covered by clamping arms, making welding much easier than it would otherwise be. Also, the Vacufix clamping system is ideal for both manual and robotic welding, which increases the versatility of the Ergofix unit. Contact Forster America today for a quote!

How to Streamline Your Operation Using 3D Modular Welding Tables

Welding equipment has come a long way in the past few decades. Instead of being simply functional and utilitarian, today you can buy welding tables, jigs, and accessories that are designed ergonomically to improve working conditions, streamline the production process, and minimize downtime.

Forster America’s 3D modular welding tables are particularly effective because they can be adjusted for any welding project, making them ideal for all those jobs that require absolute precision. They also support various table parts and a number of components that enable welders to achieve custom solutions for jobs. This makes precise measuring, aligning, and correcting, or mechanically reworking complicated work pieces considerably easier.

How 3D Modular Welding Tables Work

Forster’s 3D modular welding tables are constructed with slats comprising a T-slot system that is ideal for welding containers and casings and other complex designs. All you do is slide them sideways to accommodate the various accessories. These include:

  • 30 mm and 50 mm diameter clamping arms
  • 30 mm and 50 mm steel pipes including several that are made specifically for 3D clamping
  • A range of right-angled brackets of various sizes to meet a plethora of needs
  • Horizontal, flat, quick-release, and C clamps that fulfill every possible clamping requirement
  • A variety of stops including flat and universal stops
  • A number of other elements including V-block supports, support feet that can accommodate two cast rails to extend the modular table, table extension plates, cover plates, and adjustable angle pieces that lock

They can also be used with horizontal rotary tables, vertical turntables, and lift tables that add to the versatility of the 3D modular design.

The lifting/tilting tables are particularly useful because they can be used with specialist jigs, and can be adjusted to any degree or height. The lift and turn function is operated hydraulically so there is absolutely no effort required on the part of the welder. Streamlining an operation has never been easier.

Specifications of 3D Modular Welding Tables

Forster America’s 3D tables are available in aluminum copper (Al/Cu) alloy for welding stainless steel and in gray cast iron. Design and sizes are the same for both:

  • A width of 59 inches for a table that is 118 inches long
  • A width of 47 inches for a range of lengths: 39, 71, 79, 95, and 118 inches.

The Al/Cu welding tables feature slatted tops that are made from a combination of carbon steel and an aluminum alloy. The benefit of using this type of table when working on stainless steel is that the clamping system prevents any contact with ferritic materials that would otherwise likely cause corrosion in the form of pitting or scratching. This makes them safe and reliable. Additionally, the material has a very high tensile strength combined with a low surface hardness. Because thermal conductivity is high, there is minimal danger of spatter attaching to the table.

The top of special gray cast iron welding tables is also highly resistant to spatter. The material has a very low expansion point when it is exposed to heat, which adds to reliability.

If you are interested in using 3D modular tables in your welding workshop, call Forster America today. We’ll help you choose the best solution for your needs.

The Infinite Adjustability of Ergofix Ensures Top Quality Welding

Complex work pieces can make welding a backbreaking exercise. Furthermore, when parts that are being welded are difficult to access, the quality of work can be compromised for even the most experienced welders.

Ergofix is a welding manipulator that enables welders to adjust the height of the welding table, and manually rotate and tilt it. Because the welding table is infinitely adjustable in height, they can lower it to work over the metal or raise it to make the underneath parts more accessible. The height range is from 27.2 to 39 inches.

Once they have the work piece at the required height, the table can be rotated up to 360 degrees and tilted up to an angle of 45 degrees. This makes every inch of a work piece accessible without the welder having to bend or contort to get there. Rather, welders are able to maintain a good ergonomic posture throughout the welding process.

But Ergofix is not just about ergonomics. The fact is that when welders are standing or sitting in a comfortable position that doesn’t require physical effort, they can concentrate on achieving the best possible results. This, in turn, allows them to achieve optimal results and to produce top quality work.

The Infinite Adjustability of Ergofix

Manufactured by Forster Welding Systems, Ergofix relies on continuous hydraulic adjustment for rotation, tilting and for raising and lowering the welding table.

The welding top of the table also helps eliminate effort and improve quality. A primary feature is the rail design. Spaced 100 mm apart the rails allow the table surface to be adjusted too.

Ergofix Can be Used With Vakufix

Another benefit of Forster America’s welding table rail design is that it can be used with their high-temperature vacuum clamping plates. The patented Vakufix system allows welders to clamp parts quickly and securely, directly in line with the heat, at a three-dimensional level. Sheet metal is secured on a vacuum plate that requires a very small vacuum surface. Positioning the metal is therefore relatively easy and a lot quicker than it is when using regular clamps.

Additionally, the vacuum clamps are designed so that they can be positioned without getting in the way of welding seams. This, too, makes welding more efficient.

Vakufix comes in two forms:

  1. A set that incorporates a pump, air chamber, plate or clamping table
  2. A set with all the accessories that can be customized to work pieces

Suitable for both manual and robotic welding, it incorporates a high-temperature vacuum plate with a stainless steel surface that can be replaced easily.

Ergofix Options

There are three different Ergofix models to choose from:

  1. The Ergofix 800 that measures 31.5 x 31.5 inches
  2. The Ergofix 1000 that measures 39.4 x 39.4 inches
  3. The Ergofix 1200 that measures 39.4 x 47.2 inches

If you would like to know more about Ergofix, or order, please contact us now. We also offer swiveling welding tables for jigs, and tables for jigs that lift and tilt.
