LS (Longitudinal Seamer)

ProArc seamers are designed for straight line welding of all weldable metals of thickness from 0.1mm to 10mm. It provides 100% penetration, single pass weld on untacked cylinders and flat sheets without heat distortion to the material. This optimizes any process which reduces welding costs and improves the quality of the weld. Applications include Electric motor cases; Filter elements; Automotive exhaust; Unclear vessels; Vacuum components; Cryogenic vessels; Water tanks; Aircraft components; Coring drills; Flexible metal hose etc.

  • Special clamping unit for untacked joint
  • Precision torch movement. A machined beam and track provide accurate carriage traveling
  • Heat sinks for maximum heat removal from workpiece
  • Provide exceptional visibility around the weld head and work area
