ると共に。In the structure of the present invention, the 1% image is the three-piece bundle joint tlI! due to the arc spot #contact. ! If the upper plate and middle plate are to be welded together, oval welding holes are formed at the welding positions of the upper plate and the middle plate, and when the upper plate, middle plate, and lower plate are overlapped, these welding holes are made so that they are perpendicular to each other. It is based on the point that With this configuration, when the upper plate, middle plate, and lower plate overlap, even if the upper plate and the middle plate are displaced in the longitudinal direction of the respective welding holes due to dimensional errors, the lower plate Therefore, the welding position Kd does not change. Therefore, welding defects due to such misalignment can be reliably eliminated.
溶接条件の管理が極めて容易となるのである。This makes it extremely easy to manage welding conditions.
もつとも１本発明の上記特徴は、下板の溶接位置に中板
の溶接用孔と上板の溶接用孔とに同時に係合する係合用
突起を形成することにより。At least one of the above features of the present invention is that an engaging protrusion is formed at the welding position of the lower plate to simultaneously engage the welding hole of the middle plate and the welding hole of the upper plate.
更に、有意義となる。すなわち、このような係合用突起
を下板に形成することによって、上板。Furthermore, it becomes meaningful. That is, by forming such engagement protrusions on the lower plate, the upper plate.

る。After the middle plate and the lower plate are superimposed, it is possible to move and position the middle plate and the upper plate in the longitudinal direction of each welding hole, and the engaging protrusion protrudes in the direction of the middle plate and the upper plate. ,
The joint area increases by this protrusion, and the arc spot #
This is because the failure of O welding after I contact is greatly improved.
以下１本発明の実施例を算２図、第３図に基づいて説明

いう効果を生ずる。As explained above, according to the arc spot welding method of the present invention, the welding hole is an oblong hole, so even if the plate member to be welded is misaligned, fII contact failure will occur. This makes it possible to reliably eliminate the occurrence of misalignment, expand the tolerance range for zero position deviation, and stably obtain high welding quality. Another advantage is that the management of welding conditions becomes extremely easy.
