Today, we would like to talk about a new type of pipe welding machine forming welding method, or it is new to us, that is, the groove pipe is welded at the inner groove, unlike the previous welding outside the arc.

The forming welding method of this pipe welding machine is to form the steel strip into a groove by cold bending. When the groove is butt welded, the weld is located inside the groove. Since the groove is used to snap some things, the weld does not need to be polished, which saves the corresponding cost. It has a positive role in promoting production. The key to this welding method is to use the principle of cold bending machine to fold out the groove.

This new form of pipe welding machine has brought cost reduction to many enterprises and improved their profits.
