Welded steel pipe, also known as welded pipe, is a steel pipe made of steel plate or steel strip after being crimped and welded. Welded steel pipe has a simple production process, high production efficiency, many varieties and specifications, and less equipment, but its general strength is lower tha

The welding current in the swing welding of the straight seam steel pipe is slightly larger than that of the traditional welding method; secondly, the elongation of the tungsten electrode in the swing welding of the straight seam steel pipe is determined according to the pipe wall thickness, usually
