     EIw is to stay more than a coil around the outside of the tubes, welding, due to the "skin effect" induced current on the edge of  the pipe barrel, thus produce large amounts of concentrated heat in both sides near the place, make the pipe barrel edge and its heat to he welding  temperature, and then press the edge of a pair of pressure roller in the synthesis of welded tube together.

    In the process of welding.because there is no contact with the electrodes and the steel tube, so avoid any surface indentation, or the possibility  of loss.According to the different forming, and welding method of all kinds of electric welding pipe group production of welded pipe.
