Circumferential Seam Welding Machine

Circumferential Seam Welding Machine

Our circumferential seam welding machine with two welding drive rolls uses a DC (direct current) welding system to produce a high quality weld joint. This welding equipment delivers strong welding penetrability to ensure excellent welding results on multilayer steel plate. It can be widely used for the welding of metal basins, metal buckets, and metal cans made from low carbon steel or stainless steel. These products are used as water towers, solar water heaters, metal dustbins, fuel tanks, and more.

Features
  • Unique structure with high strength
  • Vertical and horizontal welding
  • Two welding drive rolls with silver bearing boasts consistent electrical conductivity and reduced friction to increase its production efficiency
  • Pneumatic clamp cylinders maintain the welding accuracy and allow easy operation
  • Microprocessor controlled Constant Current Regulator to accurately control the welding time and current
  • A constant direct current with negligible inductive reactance can increase the power factor
  • Small power: only 1/3-1/5 of common resistance welder. Small impact on power grid and energy efficiency
  • Large output direct current prevents heat losses in the power source and decreases the amount of splashing for a high quality weld
  • Metallic ferromagnetic clusters produced by direct current have strong penetrability to ensure quality welding spots for multilayer steel plate
