Details of joints for arc steel pipe welding process

We’ve talked about the wide application of arc welding process, and this would be great benefit for ERW steel pipe with the improvement of technology. Today, our main topic would focus on arc welding joints questions.


Two types of arc welding joints for steel pipe: with or without filler metal. It would be the molten wire when the electrodes used for the welding process, which is called MIG arc welding, such as SMAW, submerged arc welding, gas shielded protect welding, tubular wire arc welding. Depending on the characteristics of the process, the arc welding can be divided into electrode arc welding, submerged arc welding, gas shielded arc welding and plasma arc welding and so on.
