母材１，２の溶接が行われる。Then, by generating an arc from the welding torch 6 toward the groove 3, the welding base materials 1, 2 and the insert member body 5 are melted to form a molten pool in the groove 3, The weld base materials 1 and 2 are welded by solidifying the molten pool to form the weld beads 7 as shown by phantom lines in FIG.

で達する裏波８が形成される。When the weld base materials 1 and 2 are welded, the insert member main body 5 is inserted into the grooves 3 and 4 to melt the insert member main body 5 to promote the formation of a molten pool. A back wave 8 is formed in which the weld bead 7 reaches the back surface side of the welding base materials 1 and 2.
【０００６】[0006]
【発明が解決しようとする課題】しかしながら、上記従
来の溶接用インサート部材には、以下のような問題があ
った。However, the above-mentioned conventional welding insert member has the following problems.
【０００７】即ち、従来は、インサート部材本体５とし
て溶接母材１，２と全く同じ材質のものを使用していた
が、近年のように溶接母材１，２の品質が向上してくる
と、単に溶接母材１，２と同じ材質のインサート部材本
体５を使用するという考え方で溶接を行ったのでは、図
２に仮想線で示すような良好な裏波８が得られずに、図
３に実線で示すような不十分な裏波８ができてしまうこ
とがわかり、溶接不良を引起す原因となっていた。That is, conventionally, the insert member body 5 is made of the same material as the welding base materials 1 and 2, but if the quality of the welding base materials 1 and 2 is improved as in recent years. However, if welding is performed simply by using the insert member main body 5 made of the same material as the welding base materials 1 and 2, a favorable back seam 8 as shown by a phantom line in FIG. 2 cannot be obtained. It was found that insufficient back seam 8 as shown by the solid line in Fig. 3 was formed, which was a cause of defective welding.
【０００８】そこで、溶接不良の原因を調べたところ、
図３に示すような不十分な裏波８が形成されるのは、以
下のような理由であると考えられる。Then, when the cause of the defective welding was investigated,
The reason why the insufficient back seam 8 as shown in FIG. 3 is formed is considered to be as follows.
【０００９】即ち、溶接母材１，２の品質向上に伴って
材料中のイオウ分の含有率が低下される傾向にあるが、
材料中のイオウ分の含有率が低くなると、材料は溶融さ
れにくくなるため、溶接母材１，２と同じ材質のインサ

体５に溶込不良が生じて溶融プールが成長されなくなる
ので、その分、溶融プールにおける表面張力の影響が大
きくなって、開先４内の溶融プールが開先３側へ引上げ
られることとなり、裏波８の形成が不十分になる。That is, as the quality of the welding base materials 1 and 2 improves, the content of sulfur in the material tends to decrease.
When the content of sulfur in the material becomes low, the material becomes difficult to be melted. Therefore, when the insert member main body 5 made of the same material as the welding base materials 1 and 2 is used, the insertion member main body 5 has a poor penetration. Since the melt pool does not grow, the surface tension of the melt pool greatly increases, and the melt pool in the groove 4 is pulled up to the groove 3 side. Will be enough.
【００１０】加えて、インサート部材本体５に溶込不良
が生じると、これを検知した溶接制御装置からの指令に
よって溶接電圧が上昇されることとなるので、溶接電圧
の上昇により溶接母材１，２が過剰に溶融されてしま
い、裏波８が不安定化するという問題も新たに発生す
る。In addition, if a welding failure occurs in the insert member body 5, the welding voltage is raised by a command from the welding control device that detects this, so that the welding base metal 2 is excessively melted, and the back wave 8 becomes unstable, which is a new problem.
【００１１】本発明は、上述の実情に鑑み、良好な裏波

発生させることにより、溶接母材１，２やインサート部
材本体５などが溶融されて、開先３に溶融プールが形成

ることにより、溶接母材１，２の溶接が行われる。By generating an arc from the welding torch 6 toward the groove 3, the welding base materials 1 and 2, the insert member body 5 and the like are melted to form a molten pool in the groove 3 and the molten pool. Are solidified to form the weld beads 7, so that the weld base materials 1 and 2 are welded.

The insert member body 5 is melted to promote the formation of a molten pool, and the back bead 8 is formed so that the welding bead 7 reaches the back surface side of the welding base materials 1 and 2.

なる。Here, the content of sulfur in the material tends to decrease with the recent improvement in the quality of the welding base materials 1 and 2, but if the content of sulfur in the material decreases, the material Is less likely to be melted. Therefore, if the insert member body 5 made of the same material as the welding base materials 1 and 2 is used, a defective melt will not occur in the insert member body 5 and the molten pool will not grow. , The influence of the surface tension in the molten pool becomes large, and the molten pool in the groove 4 becomes the groove 3
As a result, the back wave 8 is not sufficiently formed.
【００２３】そこで、本発明では、上記インサート部材

な、良好な裏波８を形成することが可能となる。As a result, the insert member main body 5 is easily melted due to the influence of the sulfur content, the defective penetration of the insert member main body 5 is eliminated, and a sufficient molten pool is formed in the grooves 3 and 4. Therefore, it is possible to always form a good backwater 8 as shown in FIG.
