ERW is resistance welding, resistance welding with high production efficiency, low-cost, saves material, easy automation features and is widely used in various industrial sectors, such as aviation, aerospace, energy, electronics, automobiles, light industry, etc. The biggest difference between ERW steel pipe and seamless steel pipe is: ERW Pipe has welds，which is a critical factor for the quality of ERW steel pipe. With the improvement of production processes and equipment, ERW steel pipe has seen considerable development, becoming more and more mature.
