Handheld Welding Robot

 

The Handheld Welding Robot System is a 6-axis automated laser welding workstation designed for production lines handling sheet metal, frames, and tubular structures. By mounting a flexible laser welding torch onto an industrial robotic arm, this cell automates seam welding to replace manual operation, reduce skilled labor dependence, and eliminate post-weld grinding.

 

 

Supports both laser and MIG/TIG welding operations
Automated weld guidance via teach pendant.
Compatible with assembly jigs and elevated workbenches
Continuous production capabilities for 8–24 hour shifts
