Welded steel pipe production process is simple, high production efficiency, varieties and specifications, less equipment, but the general strength is lower than seamless steel pipe. Since the 1930 s, with the rapid development of high-quality strip rolling production and the progress of welding and inspection technology, the quality of welds has been continuously improved, and the varieties and specifications of welded steel pipes have been increasing day by day. Seamless steel pipes have been replaced in more and more fields, especially in heat exchange, decorative pipes, medium and low pressure fluid pipes, etc. According to the welding technology can be divided into automatic welding welding, manual welding.
