WELDING METHOD FOR PLATING STEEL SHEETS

摘要

Disclosed is a welding method for a plated steel sheet. According to the present invention, the welding method for a plated steel sheet includes a first step of piercedly forming a bead portion on a welding portion of one plated steel sheet from two plated steel sheets to be welded to each other and forming a through hole on a welding portion of the other plated steel sheet; a second step of fitting the through hole on the other plated steel sheet to the bead portion to allow the bead portion on one plated steel plate to be located on top of each other and loading the two plated steel plates stacked on top of each other on a jig; and a third step of welding the two plated steel plates to each other along the bead portion and the through hole.
