The Application of Welding Processes in Automatic Roll Forming Lines

Generally, welding processes are used in roll-forming production lines in these two situations.

One situation is to weld the front end of new strip and back end of last strip. For production using thicker and heavier materials, automated welding can effectively improve production efficiency during strip changes, and the weld quality is more consistent than that achieved by manual welding.

The other situation is to produce closed-section profiles, where the edges of the sheet metal are welded to form a closed profile after roll forming. Welded closed-section profiles produced by welding offer superior load-bearing capacity and strength compared to those produced via pressing. However, the equipment and production costs are also higher than for pressed closed-section profiles. Profile designers must conduct a technical analysis based on the specific operating conditions and performance requirements of the profile to determine which technical solution to adopt.

There are also multiple options for welding machines compatible with automated production lines, such as standard automatic welding machines, laser automatic welding machines, and robotic arm automatic welding machines.
