Abstract

PURPOSE:To furnish the joining method capable of performing satisfactory joining of the galvanized steel sheets without being affected by gasified zinc gas, CONSTITUTION:In the joining method of the galvanized steel sheets where the galvanized steel sheets 1 and 2 are superposed on each other and irradiated with a laser beam to perform welding, it is characterized to constitute this joining method of a first stage where while parts to be joined of the above- mentioned steel sheets 1 and 2 being held and press-contacted between a couple of rollers 3 and 4, energizing is executed between the rollers 3 and 4 and heat is generated by contact resistance between the above-mentioned steel sheets 1 and 2 to gasify and remove zinc and a second stage where the parts to be joined of the above-mentioned steel sheets 1 and 2 are irradiated with the laser beam to perform welding.
