The three letters ERW stand for resistance welding. Resistance welding has many excellent properties, such as high production efficiency, low cost, material saving, and easy automation. Therefore, it is widely used in various industrial sectors such as aviation, aerospace, energy, electronics, automobiles, and light industry. It is one of the important welding processes.

The biggest difference between ERW high frequency Welded Steel Pipe (ERW straight seam steel pipe) and Seamless Steel Pipe is that ERW has a weld (welded gap), which is also the most important key to the quality of ERW steel pipe. Modern ERW steel pipe production technology and equipment, due to years of unremitting efforts in the international community, especially in the United States, have made the seamlessness of ERW steel pipe a relatively satisfactory solution. Some people divide the seamlessness of ERW steel pipe into geometric seamlessness and physical seamlessness.
