Supporting Industrial Manufacturing
Welding manipulators have become essential tools in automotive, consumer goods, medical and other industries because they support the production demands of various welding applications. Manipulator welding machines can automate the handling and positioning of torches or workpieces to minimize the challenges associated with manual welding.
Explore the types of manipulators and how to select the right one for your needs below.
A welding manipulator refers to any machine, whether automated or manually operated, that assists in the welding process. A welding manipulator is used to position and move a welding torch to maintain a consistent weld. The equipment is useful for projects requiring especially high-quality welds on large or complex components.
Most manipulators have one or more axes of movement to move a welding torch to follow a specific path along the workpiece, or they may rotate and tilt the workpiece so the welding torch can remain stationary.
Enhanced Positioning for Superior Results
Welders use a welding manipulator to do the following:
Three popular types of welding manipulators include rotary welding positioners, rollers and column and boom welders. Each serves a distinct function, and welders can often use them together to achieve specific results. Here is a look at the types of welding manipulators.
Rotary welding positioners hold a part or weldment at one end and rotate it, allowing welders or welding machines to access specific areas that need welding. These positioners come in various shapes and sizes, ranging from simple models with a single axis of rotation to advanced designs with four or five axes. Welders typically pair them with a tailstock to support the opposite end of longer or heavier parts.
Positioners with three or more axes can handle even the most complex or oddly shaped parts, making it easier for welders to access challenging areas. Some rotary positioners have tilt functionality, which allows the operator to adjust the angle of the platform and position the equipment for various welding tasks.
Rollers serve a similar function to rotary welding positioners. They operate differently. Instead of supporting a weldment or part at both ends, the weldment rests on the rollers and is rotated to give the welder access to the necessary surfaces. This design best suits cylindrical parts, such as pipes and storage tanks, which can easily roll.
Rollers are particularly useful for handling pipes with large diameters that would be challenging for a rotary welder welding positioner’s headstock or tailstock to support, making them an ideal alternative for parts that exceed the rotary welding positioners’ capacity.
Column and boom manipulators serve a different purpose than rollers and rotary positioners in automated facilities. Instead of holding the weldment, they support the welding torch. These manipulators typically weld parts supported by either rotary positioners or rollers. Most have two degrees of freedom, moving vertically and horizontally in one direction, with some capable of rotating around their base. They often control the torch’s angle and distance from the welding surface.
Column and boom welding manipulator sizes range from a few feet tall and wide to several stories tall, depending on the application. Smaller column and boom units are generally used with rotary welding positioners, while larger units are necessary for welding large-diameter pipes and tanks when working with rollers.
Industry Solutions
Welding manipulators are vital to the following industrial applications:
The automotive industry relies on welding manipulators to meet production volumes and ensure structural integrity. Welders use the equipment to assemble vehicle frames and repair or replace an exhaust system. With the rise of electric vehicles, engineers use manipulators to join battery cells and to ensure safety when assembling sensitive electronic components.
Aesthetics and structural integrity are often top priorities in consumer goods. Manufacturers use manipulators to guarantee clean and precise welds when assembling appliance frames and casings or electronic housings and enclosures.
Welders may use welding manipulators to fuse surgical instruments or medical equipment frames and enclosures.
Welding manipulators support the production of pipelines, tanks and pressure vessels. These solutions ensure infrastructures can withstand extreme environmental conditions.
Heavy equipment manufacturing, including machinery used in construction, mining and agriculture, benefits from welding manipulators because they allow precise welds in hard-to-reach or unusually shaped parts. The equipment can also lift and move paving slabs and other structural components.
Welding manipulators are invaluable in defense manufacturing, where products must often withstand extreme conditions. Welders can use manipulators to fabricate armored vehicles and assemble weapon system components.
