溶接物の片側に取付けて溶接することを特徴とする片面
溶接法である。That is, the present invention is a method for welding materials such as aluminum or aluminum alloy from one side, and a thin plate material made of a material such as stainless steel having a higher melting point than the above-mentioned material and a back side other than the above-mentioned material on the back side of the weld groove line. This is a one-sided welding method in which the material is attached in advance to one side of the object to be welded.
次に第１図、第２図により本発明の溶接法の実施例につ
いて説明する。Next, an embodiment of the welding method of the present invention will be described with reference to FIGS. 1 and 2.

て固定されている。In FIGS. 1 and 2, 1 and 2 are the objects to be welded, 4 is a self-raising material made of the same material as the objects 1 and 2 to be welded, and this backing material 4 is the object to be welded 1 and 2. It is fixed by attachment welding 8 to either of the two.
７はステンレス鋼製の薄板例えば１９ＵＳ −３０４，
０，３闘厚さの裏当材である。7 is a thin plate made of stainless steel, e.g. 19US-304,
It is a backing material with a thickness of 0.3 mm.

通常Ｔ工Ｇ溶接で施工するが、厚板についてはＭ工Ｇ溶
接で行なっても良い。Now, Figs. 3 and 4 show welding performed on the weld groove configured as shown in Figs. 1 and 2.
The figure shows butt welding, and Figure 4 shows fillet welding. The welding method is usually T-work G welding, but for thick plates, M-work G welding may be used.
第３図、第４図において、１，２は溶接される被溶接物
、３は溶接によシ開先内へ充填された溶接金属である。In FIGS. 3 and 4, 1 and 2 are objects to be welded, and 3 is a weld metal filled into the groove by welding.

裏当材４と溶着しない。In this way, the grooves shown in FIGS. 1 and 2 are combined with the grooves shown in FIGS.
When welding is performed as shown in FIG. 4, the molten weld metal 3 cannot melt the stainless steel thin plate 7 shown in FIGS. 3 and 4 because the melting point of the stainless steel thin plate 7 is high. A Uranami bead is formed in the shape of a thin stainless steel plate 7 and a backing material 4 made of the same material. In this case, weld metal 3
Since it is blocked by the stainless steel thin plate material 7, it is not welded to the backing material 4 made of the same material.
したがって、従来法である第５図、第６図の０５．０６

接触部にノツチを形成しないことから、割れなどの欠陥
発生の恐れはない。Therefore, 05.06 in Figures 5 and 6, which is the conventional method,
Since no notch is formed at the contact portion between the welded materials 01 and 02 and the fixed backing material 04 as shown in FIG. 2, there is no fear of defects such as cracks occurring.
