The system has been applied in the “West East Pipeline Project” and its performance is proven. With this welding machine the welding parameters can be either preset before or adjusted in real time during the welding process, which avoids the blemishes of same type domestic and international products. Thus it is best propitious to in situ construction conditions and workers’ technical level in China. In this article the development of mechanical and control systems of this product is introduced and typical welding procedure parameters are provided.展开更多
