Zusammenfassung:	PROBLEM TO BE SOLVED: To prevent the matters of burn through and the falling of sagging to the inside caused by welding, and also, to prevent the generation of cracks after welding.SOLUTION: In the welding joint in which the inside is made hollow in a state where the joining face 11a of a first member 11 and the joining face 12a of a second member 12 are butted and are joined by welding, the welding joint is provided with a projection 15 to be provided projectingly from the inner fall face 11b forming into the hollow of the first member 11, the tip 15a is extensively formed to cover the inside of a melting part 13 at which the respective faces 11a, 12a are melted while being separated from the internal edges of the respective joining faces 11a, 12a in a state where the respective joining faces 11a, 12a are butted, further, the base end 15b projecting from the inner wall face 11b is continued to the inner wall face 11b via a curbed face 15c, and is continuously formed over the whole circumference of the inside of the respective joining faces 11a, 12a.
