ERW tube is "high frequency resistance welded steel tube", which is different from the welding process of ordinary welded tube. The weld is made of the base material of the steel belt body, and the mechanical strength is better than that of ordinary welding.
ERW stands for resistance welding. Resistance welding is widely used in aviation, aerospace, energy, electronics, automotive, light industry and other industrial sectors because of its high production efficiency, low cost, material saving and easy automation. It is an important welding process
Straight seam high frequency welded pipe (ERW steel pipe) is formed by forming a hot-rolled coil through a forming machine. The skin effect and proximity effect of high-frequency current are used to heat and melt the edge of the pipe blank. Pressure welding is carried out under the action of a squeeze roller. Realize production. Welded steel pipes have simple production process, high production efficiency, many varieties and specifications, and less equipment, but their general strength is lower than seamless steel pipes.
