SWM Series Internal and External Straight and Circular Seam Submerged Arc Automatic Welding Machine
Product Overview
Solving your business pain points through innovative technical solutions
The SWM series internal and external submerged arc straight and circular seam automatic welding machine is mainly used for automatic welding of internal straight seams, external straight seams, and butt circular seams of pipes and pressure vessel cylinders. The equipment consists of a cross cantilever welding machine, drive roller frame, ultra-compact submerged arc welding head, submerged arc welding power source, vision system, etc. Configured with an ultra-compact submerged arc welding head that can extend into pipes and vessels with a minimum inner diameter of Φ300 for internal straight seam or circular seam welding. The welding formation can be viewed on the operation panel through the vision system, offering extremely high operational convenience and welding stability.
