Product Overview
Solve your business pain points through innovative technical solutions
The SWM Series internal and external submerged arc longitudinal and circumferential seam automatic welding machine is mainly used for automatic welding of internal longitudinal seams, external longitudinal seams, and girth welds of pipes and pressure vessel shells. The equipment consists of a cross-type boom welding machine, drive roller beds, an ultra-compact submerged arc welding head and submerged arc welding power source, a vision system, etc. With the ultra-compact submerged arc welding head, it can be inserted into the interior of pipes and vessels with a minimum inner diameter of Φ300 to perform internal longitudinal or circumferential seam welding. The vision system allows the internal weld formation to be viewed on the operation panel, offering excellent operating convenience and welding stability.
