Summary of welding process and common problems of 304 stainless steel seamless pipe
The 304 stainless steel seamless pipe is made of imported first-class regular stainless steel plate. Its characteristics are: no blisters, no sand holes, no black spots, no cracks, and smooth weld bead. Bending, cutting, welding performance advantages, stable nickel content. The welding process of 304 stainless steel seamless pipe adopts flat characteristic welding power supply, which is used in direct current (welding wire connection). Generally, pure argon gas (purity is 999% or Ax+2‰02, 20°25/min is suitable for the flow.
