Abstract

PURPOSE: To obtain a titled nozzle which consists in coupling a welding core opposing to the groove, a contact tube, supply and return pipes for cooling water, a shielding gas supply pipe and impurity gas suction and discharge pipes into one row plate shape and which makes narrow groove welding easy even for plates.
CONSTITUTION: A shielding gas supply pipe 4 and suction and discharge pipes 5, 6 for impurity gas are disposed in one row, by holding a contact tube 1 for feeding a welding core 9 to the groove and a cooling water feed pipe 2 and its return pipe 3 for the purpose of cooling water circulation at the center. The outside surface of the entire part of this configuration is covered with a heat-resistant electrical insulator 10, whereby the nozzle for narrow groove MIG welding is formed. According to this nozzle for welding, the groove width that can be welded may made extremely small. In addition, the flow alignment to the groove bottom is accomplished despite the suction and exhausting of the impurity gas around the weld zone and the spouting of the shielding gas supplied 4 from the fine diameter injection port. Hence, the purity of the shielding gas may be increased.
