作業性が悪くなる欠点があつた。 In this conventional and improved welding method, welding is performed from the V-shaped groove 3 side, but in order to eliminate unwelded parts, welding is performed from the V-shaped groove 3 side, and then welding is performed from the V-shaped groove 3 side. The back side of the joint 201 on the back side is reversed, and the joint 201 removed by the reverse side is welded. Therefore, it is necessary to turn the back, back weld, and reverse the first and second welding materials 1 and 2,
It had the disadvantage of poor workability.

In the figure, the same parts as in FIGS. 1 and 2 are designated by the same reference numerals. In FIG. 3, the J groove 4 is provided at the end surface joint 201 of the second welding material 2 to form the joint 201 into a protruding shape, and the tip of the joint 201 is formed into a flat plate shape. ing. The groove-shaped groove 5 is the first welding material 1
is provided in a groove shape in the vicinity of the surface joint portion 101,
The joint portion 101 is formed into a protrusion shape similar to the protrusion-like joint portion 201, and the tip of the joint portion 101 is similarly formed into a flat plate shape.
