Abstract

PURPOSE:To save the time required for treating a cable during the pass time and improve the arc time ratio, by reversing the welding directions at every pass to reset the welding conditions until the last layer is welded. CONSTITUTION:A welding head 4 is set on top of a guide rail 6, then a traveling apparatus is driven by a controller 1, and a welding torch 9 and a wire feeding mechanism 11 b are actuated to start arcing. Then welding is performed under first welding conditions, an commanding element at the position where the descending posture is changed into an ascending posture is detected by a detector 16b, and based on the resulting signal the welding head 4 rotates one time. Thus the command element detected at the start of welding is sensed, and the welding is stopped at the sequence for stopping welding. After one pass of circumferencial welding has been completed the welding direction is switched and welding a second pass is carried out. The same procedure will be performed until the last layer is welded.
