Welding, abbreviated as ERW,
ERW pipe is a kind of "high frequency resistance welded steel pipe", which is different from ordinary welded pipe. The weld is formed by melting the base metal of the steel strip body, and its mechanical strength is better than that of ordinary welded pipe. Liaocheng Jinhuiyuan Steel Pipe Co., Ltd. operates high-frequency welded pipes.
ERW stands for resistance welding, which has the characteristics of high production efficiency, low cost, material saving and easy automation, so it is widely used in aviation, aerospace, energy, electronics, automobile, light industry and other industrial sectors, and is one of the important welding processes.
