必要とするためコストアップを招来する。As shown in FIG. 4, the lightweight sand inch material is constructed by integrally layering a highly rigid resin (2) such as polypropylene or nylon between metal plates such as steel plates or aluminum plates. When joining this lightweight sand-inch material to other metal materials at °C, the method of adhering to the same metal material through an adhesive is often adopted, but the cost of the adhesive is high and the number of steps required for bonding is high. Since equipment is required for bonding, costs increase.
これを解消するためにはスポット溶接による接合方法が
よいが、前記軽量サンドインチ材においては中間の樹脂
（２１の厚みが０．２〜０．８Ｍと比較的厚く、同樹脂
が電気を通さないのでスポット溶接が不可能である。In order to solve this problem, it is better to join by spot welding, but in the lightweight sand inch material, the intermediate resin (21) is relatively thick at 0.2 to 0.8M, and the resin does not conduct electricity. Therefore, spot welding is not possible.
このため軽量サンドインチ材の外側金属板に突起を設け

サンドイツチ材の接合に適用されるものである。As described above, in the present invention, a protrusion is attached to the other metal material to be joined without any special processing on the lightweight sand inch material, and the protrusion is used to join the other metal material. According to the present invention, the lightweight sand inch material having a relatively thick intermediate resin layer can be brought into contact with the projection bath without applying any special processing to the same material. The method of the present invention can be easily, reliably, and economically welded to a mating metal material by the method, and the method of the present invention is applicable to joining lightweight sand german materials for automobile sunshades, hoods, trunk lids, etc. It is.
以下本発明を図示の実施例について説明する。The present invention will be described below with reference to the illustrated embodiments.
