What Is The Welding Process?

Welding is the process of generating intense and focused heat in a specific area to melt and bond metals. The melted metal is often referred to as molten liquid. Although this state is temporary, it can lead to complications. One significant challenge beginners face is the position in which the welding occurs. A standard weld is flat and horizontal. To ensure easy access, the welding gun must maneuver over the metal, which must be carefully positioned.

What Are Welding Positioners?

If you are new to welding, you may be curious about what a welding positioner is. Welding positioners are primarily used in manufacturing facilities, by welders, and in welding workshops to position and move weldments during the welding process.

How Do Welding Positioners Help In The Welding Process?

Using welding positioners to position the metal workpiece enhances productivity and increases the rate of welding deposition. They also improve the quality of the welds and significantly reduce errors. Furthermore, welding positioners minimize the movement of workpieces, helping to meet the required welding specifications. Once the metal workpiece is positioned, it remains in place, which reduces the operator's effort to hold and position it manually.

Additionally, welding positioners optimize floor space during the welding process, enable the use of robots for welding operations, and increase safety during operation. With a welding positioner, the welder can work on large parts without needing to move to access joints or overheads.

Different Types Of Welding Positioners

Welding positioners come in various types, classified based on functionality. They fall into three main categories: manual welding positioners, semi-automatic welding positioners, and automatic welding positioners.

Manual Welding Positioners

Manual welding positioners are operated using foot pedals to move the weldment in the correct direction and at the appropriate speed.

Semi-Automatic Welding Positioners

Semi-automatic welding positioners integrate additional equipment to boost productivity and improve yield. They combine the welding positioner with a torch stand, enabling semi-automatic welding with the positioner pushing the workpieces beneath a static torch. These torches are equipped with devices that oscillate the weld head to create large weld fillets, ensuring consistent speed and positioning for greater repeatability.

Automatic Welding Positioners

Automatic welding positioners operate smoothly in automated welding stations, which include the welding positioner and a robot. This setup can produce large quantities of highly precise and accurate welds, facilitating mass production supported by robotics.

Applications Of Welding Positioners

Welding positioners are instrumental in simplifying various welding operations. Their primary application is in rotating parts for welding and assembly tasks. They are utilized across multiple industries, including automobile manufacturing, aerospace, construction, steel fabrication, pressure vessel fabrication, pipe fabrication, and machinery manufacturing.

Available Options Of Welding Positioners

There are numerous options available for welding positioners, such as customized colors, special coatings, tailored frame widths, custom central guards, and operation modes that offer continuous, flexible, or oscillating options. You can also find customized index times and reinforced cam followers that enhance stationary force, along with customized servo bands.

Welding positioners can operate on a single axis or multiple axes. Single-axis welding positioners are designed as a single unit to minimize overhang. In contrast, units intended for extensive overhang include a head and tailstock, with adjustable tailstocks to accommodate parts of varying lengths.

For those looking to increase production capacity or fabricate more complex parts, multi-axis welding positioners are a suitable choice. They typically employ a dual trunnion arrangement mounted on a rotary table, enabling the operator to load components and rotate them into position for welding while simultaneously loading another part.

Careful Considerations When Purchasing Welding Positioners

Price is always a consideration when purchasing a welding positioner. The chosen brand should deliver extreme accuracy and low to zero backlash options. A complete welding positioner solution is recommended, which includes fixed and custom lengths, heavy-duty frames, and riser bases. An efficient head and tailstock welding positioner provides high accuracy and can be operated on a rotating table or mounted in a vertical position. Reducing your footprint while managing large quantities with compact units can lead to considerable overall savings.

Ensure that the machines are protected from corrosion with appropriate paint finishes. It is also vital for welding positioners to have holes to accommodate utilities and provide quick access to piping and wiring components.

Some welding positioners come equipped with customized controls and program control panels that establish flexible automatic systems and can be integrated with robotics to enhance productivity.
