1.Angle Automatic Longitudinal (Straight) Seam Welding Machine is mainly used for the high quality and low distortion automatic straight welding of the square tube,rectangular tube and special shaped pipe 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.

Main Technical Parameter

Above is standard model only, we still can special design the welding length according the weldment length requirement.
And if adopt Plasma welding source to work with this machine,the maximum welding thickness can up to 8mm.
Machine colour also can customize base on customer requirement.
