METHOD FOR JOINING COATED METAL SHEETS BY LASER WELDING, AND A JOINT

摘要

The invention relates to a method for joining coated metal sheets to each other by welding, in which method the sheets (2,3) are connected by laser welding in such a way that a joint (1) is achieved between the metal sheets, which joint comprises at least one such section L in which the sheets (2,3) to be connected overlap with an auxiliary sheet (4), and that in the method an additive (5) has been formed or is formed between the coated metal sheets to be joined by welding, for protecting the edges to be joined of the metal sheets from corrosion, which additive is activated for sealing the joint. The invention also relates to a joint.
