Abstract
PURPOSE:To decrease the generation of perforation of a junction by placing a band-like metallic plate end part on a step difference part of a back bar in which a step difference being equal to plate thickness of the band-like metallic plate is formed, superposing other metallic plate end part thereon by a minute quantity and welding and joining them. CONSTITUTION:Each end part of band-like metallic plates 10, 22 is superposed on each other by a minute quantity and welded and joined. In this case, a step difference part (step difference quantity l) being roughly equal to plate thickness of the band-like metallic plate 10 superposed to the lower side is formed in a back bar 31. Subsequently, an end part 10A of one band-like metallic plate 10 is placed thereon, an end part 22A of the other metallic pate 22 is superposed on this end part 10A by a minute quantity and each band-like metallic plate 10, 22 is welded and joined by an electrode 30A of a welding touch 30. In such a way, warp of the band-like metallic plate of the upper side can be prevented.

る帯状金属板の接合方法及びその装置に関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a method and apparatus for joining band-shaped metal plates, and particularly to a band-shaped metal plate for joining the ends of flexible A1 alloy band-shaped metal plates. This invention relates to a method for joining plates and an apparatus therefor.
従来、帯状金属板の接合方法には、帯状金属板同士を溶
接して接合し、その溶接接合部を圧延する接合方法があ
る。Conventionally, as a method for joining band-shaped metal plates, there is a joining method in which band-shaped metal plates are welded together and the welded joint is rolled.

発生する。However, when welding the strip metal plates together, welding was performed by blowing out shielding gas from both the upper and lower directions of the welding torch side and the back bar side, but the shielding gas is blown out uniformly from the back bar side. It is difficult to
When the blowing pressure varies and a thin plate is melted to the back side (Uranami welding), holes occur in areas where the blowing pressure is strong.

９−２４５２６号公報）。In addition, the belt-shaped metal plate is not sufficiently melted and sufficient back wave welding is not possible, resulting in poor fusion at the weld joint at the welding start end, or conversely, excessive arc heat is applied immediately after welding starts, causing the melt to drop. There is a problem that holes may occur due to
