Abstract

PURPOSE: To conduct the shielding gas injected from a nozzle into the groove, fill within the groove and prevent the formation of blowholes by working shielding gas guiding slopes to the upper part of the deep narrow groove formed between two members.
CONSTITUTION: A deep narrow groove 9 is formed between end faces 61, 71 opposing to members 6, 7 in proximity, and the upper part of the groove 9 is expanded by slopes 63, 73, and is thereby metched approximately with the inside diameter of an injection nozzle 2. Next, a backing strip 5 is fitted on the back side of the groove 9, and a welding torch 1 is opposed toward the center of the groove 9, thence with the injection nozzle 2 held approached to the members, welding is started. Then, the central part of the shielding gas flow from the nozzle 2 directly strikes the inside part of the groove 9, and the outside circumferential part of the gas flow in conducted by the slopes 63, 73 into the groove 9. Hence, the greater part of the injection gas flow flows into the groove 9, thereby preventing the influx of air and welding the narrow groove 9.
