Abstract

PURPOSE:To make the thorough fusion in the toe of weld parts in a groove by making high current time long and low current time short in a weaving pattern at which weaving welding is accomplished by using a non-consumable type welding torch. CONSTITUTION:After root pass welding is carried out in a groove 4 formed by the end parts 6 of butted pipe materials 3, build-up welding is carried out by weaving a welding torch 1 in the groove 4 in the direction perpendicular to the direction where the torch moves along the circumference of the pipe. In the weaving pattern of a non-consumable electrode 5 of this case, large current is flowed in both ends 7a, 7b of the groove 4, and while it moves durig this time, welding is carried out with low current. The stop time of the electrode 5 in both ends 7a, 7b of the groove 4 is made long, whereby the weld metal from a filler rod in both ends 7a, 7b is thoroughly fused to the weld metal of the previous process, and the perfect weld zone is formed with superior working efficiency.
