Longitudinal Seam Welder

L.S. (Longitudinal Seamer) ProArc seamers are designed for straight line welding of metals with a thickness ranging from 0.1mm to 10mm. The L.S. provides 100% penetration, single pass weld on untacked cylinders and flat sheets without heat distortion to the material. This optimizes the weld process and improves the quality. Application: 
Electric motor cases, filter elements, automotive exhaust, nuclear vessels; vacuum components, cryogenic vessels, water tanks, aircraft components, coring drills, flexible metal hose…etc.
  • Servo Motor drive system.
  • Special clamping unit for untacked joint.
  • Precision torch movement with machined beam and track providing accurate carriage travel.
  • Heat sinks for maximum heat removal from the workpiece.
  • Outstanding visibility around the weld head and work area.
  • Copper finger clamping provides uniform heat removal and Arc-Blow is virtually eliminated.
  • Thin material (under 0.4mm) continuous holding strips.
  • Riser block for cylindrical work greater than 770mm.
  • Pneumatic mandrel latch unit.
  • Pneumatic torch lift.
  • Wire-feeder system.
  • Programmable carriage control.
  • Automatic pneumatic alignment gauges.
  • Limit switch and return home.
