Abstract
PURPOSE: To enable to weld efficiently keeping a high shielding effect, by forming broken at the tip end of inside nozzle and also, forming outside nozzle in flat in weld line direction.
CONSTITUTION: The broken part 6 is formed at the lower part of the tip end part of the inside nozzle 1a and the diameter 1 of the nozzle 1a is made small. Then, the aimed position of the wire 5 is kept accurate and shielding effect is heightened by by shortening the distance between the arc point and the nozzle 1a. The opening parts 7a, 7b are formed providing the flat outside shelding gas nozzle 7 outside of the nozzle 1a in the weld line direction and outside shielding gas is sent to the left and right opening 7a, 7b through the branch pipes 10a, 10b after sending in the storage 9 through the supply tube 8. By the above double shielded gas nozzle, blockade accident of the nozzle by sputtering adhesion, is repressed and continuous welding is able to carry out for many hours.
