この発明は、自動車の車体鋼板等の薄い鋼板の
接合方法の改良に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a method for joining thin steel plates such as automobile body steel plates.

る。 The body of an automobile is made by press-forming a number of steel plates into a predetermined shape, stacking them on top of each other, and joining them by spot welding or the like. As shown in Fig. 1, the joint surface is generally made by bending the end of the inner steel plate 1 inward by the thickness of the outer steel plate 2, and attaching the outer steel plate to the bent end of the inner steel plate 1. Stack 2,
Join by spot welding etc. The outer surfaces of the inner and outer steel plates 1 and 2 are mainly coated to prevent rust. In that case, when painting directly, the coating film 3 is sprayed as shown in Fig. 2, but the coating film 3 is difficult to adhere to the outer corner 4 of the edge of the outer steel plate 2, and the coating film 3 in this area is It becomes thinner and has the disadvantage that rust occurs early in this area. To avoid this, as shown in Figure 3, the outer steel plate 2 and the inner steel plate 1 are
A vinyl chloride sealant 5 is applied and sealed in the depression between the holes to make the surface almost flat, and a coating film 3 is applied on top of it.
All you have to do is form it. However, when applying the sealer material 5, it flows easily and it is difficult to apply it evenly.
The work requires skill, is troublesome, and is extremely costly.
この発明は、かかる点に鑑み改善したもので、
以下本発明を第４図及び第５図に示す実施例につ
いて説明する。 This invention has been improved in view of these points,
The present invention will be described below with reference to the embodiments shown in FIGS. 4 and 5.
内側の鋼板１と外側の鋼板２の薄い二枚の鋼板
の端部を溶着して接合する場合、外側の鋼板２の
端部数mmに亘つてメツキ被覆６する。メツキは、
亜鉛メツキが適当である。メツキ被覆６は、厚さ
が数ミクロンで、その厚さが薄いので、殆んど段
がつくような影響がない。そして、外側の鋼板２
の端部を内側の鋼板１の端部の内側に凹ませた部
分に合わせ、スポツト溶接等によつて接合する。
そして、外面には塗膜３を塗付して塗装する。 When the ends of two thin steel plates, the inner steel plate 1 and the outer steel plate 2, are joined by welding, the edges of the outer steel plate 2 are coated with plating 6 over several millimeters. Metsuki is
Zinc plating is suitable. The plating coating 6 has a thickness of several microns, and since it is thin, there is almost no step-like effect. And the outer steel plate 2
The end of the steel plate 1 is aligned with the inwardly recessed end of the inner steel plate 1, and the two are joined by spot welding or the like.
Then, a coating film 3 is applied to the outer surface.
しかして、外面に塗膜３を塗付するとき、外側
の鋼板２の端部外側隅部４は、突起状で、塗膜３
が乗り難く薄くなる。しかし、この部分にはメツ
キ被覆６があるので、錆の発生を防止できる。 Therefore, when applying the coating film 3 to the outer surface, the edge outer corner 4 of the outer steel plate 2 has a protruding shape, and the coating film 3
becomes difficult to ride and becomes thin. However, since there is a plating coating 6 on this part, it is possible to prevent the occurrence of rust.
以上説明したように、この発明は、薄い二枚の
鋼板の端部を重合して溶着によつて接合するもの
に於て、外側の鋼板の端部にメツキ被覆して内側
の鋼板の端部に重ねて溶着し、外面を塗膜で塗装
するようにしたので、外側端部隅部に塗膜がつき
難いことがあつても内側にメツキ被覆があるので
錆の早期発生を防止できる。そして、メツキ被覆
は、外側の鋼板端部に部分的に施こせばよく、安
価にできる。又、メツキ被覆層は極めて薄いの
で、盛り上り等外観上、製作上の問題が発生する
こともない。 As explained above, in the case where the ends of two thin steel plates are joined by overlapping and welding, the ends of the outer steel plate are coated with plating, and the ends of the inner steel plate are coated with plating. Since the outer surface is welded and the outer surface is coated with a coating film, even if the coating film is difficult to adhere to the corners of the outer edge, since there is a plating coating on the inner side, early formation of rust can be prevented. The plating can be applied only partially to the outer edge of the steel plate, and can be done at low cost. Furthermore, since the plating coating layer is extremely thin, problems in appearance and manufacturing such as swelling do not occur.
