Document Type and Number:
Japanese Patent JP3525977
Kind Code:
B2
Abstract:

PROBLEM TO BE SOLVED: To reduce the working time, to improve the safety in the working, and to provide a joint of high strength with an excellent bead shape.
SOLUTION: Plate members 1, 2 are arranged in a substantially horizontal manner while slightly separated from each other, and a non-consumable butt strap 4 is arranged on a back side of a groove part 3, and the butt strap 4 can be moved in the welding direction. A recessed part having an arcuate or flat bottom surface of 0.5-20mm depth is formed in the non-consumable butt strap 4. The arc is generated at the tip of a welding wire 6 by butting a welding torch 5 to the groove part 3 with the torch 5 downward from an upper part and the plate members 1, 2 are welded to each other by slidingly moving the butt strap 4 in the same direction as the welding direction as the welding torch 5 is moved. The flux-cored wire in which the quantity of the slag generating agent based on the total weight of the wire is 1-11wt.% is used for the welding wire to be used.
