Main Features And Applications:
1. Automatic Longitudinal (Straight) Seam Welding Machine is mainly used for the high quality and low distortion automatic straight welding of the metallic cylinders and aligned plates made with stainless steel, iron, aluminum and brass, etc.
2. Adopted plate type or key type copper pressing mechanism according to welding requirement of various materials.
to provide regular and stable clamping and cooling effect.
3. Adopt PLC control or Relay control, and DC motor drive, achieve welding speed stepless adjustable.
4. Special designed back protective copper block and molding slot, to assure the stable gas shield and ensure double side forming in single side welding. 
5. Apply to cooperate welding with TIG, MIG, MAG and Plasma-Arc welding source.
