Abstract

PURPOSE:To prevent the occurrence of flawing and improve working efficiency at the welding by forming protrusions on the back side surface of a synthetic-resin coated steel plate, compression-bonding the same and performing indirect spot welding in bonding said steel plate. CONSTITUTION:At the time of forming a top plate a or the like for gas ovens by bonding a steel plate 2 having been coated with synthetic resin 1 and the tongue pieces b'' of bonding pieces b', protrusions 3 are beforehand formed to the tonque piece B'' face by press-molding or the like and are compression-bonded by a press 6 so as to prevent giving any flaws to the surface at the time of fabrication. The resin layer 1 is ruptured by the protrusions 3. On the other hand, electrodes 4, 5 are beforehand contacted to the back side of the protrusions 3 and the back of the steel plate 2 on the front side and indirect spot welding is done through the protrusions 3. The protrusions 3 are crushed and the steel plates 2, 2 are bonded. As compared to the conventional method of welding after peeling the resin layer, working efficiency is higher and the occurrence of flaws, etc. at the working is prevented.
