Abstract

PURPOSE:To decrease the number of stages and to shorten remarkably a work time, by interposing a hollow metallic rod between base metal metallic plates, placing a backing material, melting the metallic rod, forming a welding thick part between the base metals, and executing the welding. CONSTITUTION:A cylindrical metallic rod 6 having a hollow part 601 consisting of the same material as the base metal is interposed between each of them, and tack welding is executed without edge preparation at tip faces 102, 202 of base metal plates 1, 2. Also, a backing material 7 consisting of a glass fiber material, etc. is fixed to the reverse side of the tip parts 102, 202 of the base metals 1, 2. Subsequently, a welding wire, etc. are melted by a high temperature together with the metallic rod 6 having the hollow part 601, both the surface and the reverse side of the base metals 1, 2 are welded, and a weld zone 8 is formed.

, is performed as shown in (b). First, Figure 2 (a)
As shown in 1st. Second base metal plate (1), (2
) between the tip surfaces (102) and (202), for example,
1st. A metal rod (6) having a center portion (601), which is a cylindrical metal made of the same material as the second base metal plates (1) and (2), is interposed by, for example, temporary welding, and the first base metal plate (1) and (2) are interposed, for example, by temporary welding.
A tape made of glass fiber material, for example, is attached to the back surface of the tip of the second base metal plates (1) and (2) so that it does not melt during welding. Second base metal plate (1).

る。A backing material (7) made of feed that does not mix with (2) and cause any adverse effects is fixed by a magnet or the like. This backing material (
7) acts as a leak stopper for lava metal, and 1. The second is to make the back side of the tip of the metal plate (island (2)) usable for welding at the same time. Next, as shown in Figure 2 (b), welding wire (not shown) or welding is used. Rod (not shown)
is melted together with the metal rod (6) having the middle rough part (601) by high heat, and the leakage is prevented by the backing material (7). Second base metal plate (1), (2
) are simultaneously welded to form a welded portion (8).

を形成することができる。This invention has been made as described above, and a metal rod (6) having a hollow portion (601) that is melted by the high heat generated during welding.
However, because it comes into contact with a backing material (7) such as a tape made of glass fiber material and stops, it consumes the same amount of welding wire (not shown) or welding rod (not shown) as in the past. , it is possible to generate a large amount of weld metal in a short period of time, and this weld metal is the first. Second base metal plate (1)
, (2) can be completely fused to form a weld on both the front and back surfaces at the same time.
