There has been proposed a method of conveying and guiding a strip-shaped steel sheet on the assumption that it is welded in a specific manner. That is, as shown in FIGS. 15 and 16, the side ends of the strip-shaped steel plates a and b on the welding side are adjacent to each other, and one of the side ends is guided by the guide members c and b in the same vertical plane. There is disclosed a method of conveying and guiding a strip-shaped steel sheet to be brought into contact with a surface, and to be fed to a welding machine e by being brought into contact with each other without any gap in the same horizontal plane on separate conveying planes arranged side by side and inclined at an acute angle α.

In this configuration, when the welding by the welding machine e is converged by the grip roller f and path-constrained, for example, when laser beam welding is performed, a rapid amount of heat is supplied at once to the butted portion of the strip-shaped steel plate by the laser beam. Therefore, welding may cause a problem that the welded portion is thermally deformed by welding, making it difficult to secure stable welding accuracy and deteriorating the properties of the welded portion obtained by welding. This phenomenon is particularly remarkable when welding strip-shaped steel plates having different thicknesses.
