Abstract

PURPOSE: To obtain uniform beads over the entire pipe length, by installing the conductive member parallelly to the weld line in the back plane of the weld zone, at the position just under the weld line keeping a specified distance, and by welding while controlling the current value flowing through the conductive member, so as to erase the increment of the leakage flux due to the welding current in the end portion of the steel pipe.
