Abstract

PURPOSE: To perform TIG welding of high efficiency by applying distributed welding of one layer 2 pass padding in the intermediate layer, inclined padding that does not perform weaving on the lower side wall face of a beveling and becomes thick in the groove deeper side and thin in the groove opening side, and padding welding while applied weaving on the upper wall face inside the angle groove part.
CONSTITUTION: On a welding metal 5 of the first layer of the intermediate layer following the initial layer bead 4, its under side pass is made padding in the groove deeper side thick and the groove opening side thin without weaving. Therefore, inclined padding such as spreads in the groove open side is formed, and the angle O2 between the upper side groove wall 6 and the welding metal 5 surface is remarkably large, which allows weaving welding. In this way, the upper side welding metal 7 is formed, and below it further the 2nd layer 2 pass welding is kept going while applying straight rod operation to the lower side, and weaving rod operation to the upper side.
