METHOD OF ASSEMBLY BY DISCONTINUOUS THERMAL WELDING ALONG THE JOIN OF A STEEL SHEET WITH AN ALUMINIUM SHEET, WITH DEPOSITION OF A CLEAN MATERIAL TO FORM A SEALED JOINT ON THE JOIN

摘要

The invention describes a process for assembly of two sheet metal elements (1, 2), one of which is made of steel and the other of aluminium, comprising a thermal welding step of the two sheet metal elements using an filler material. A V-shaped joining face (3) is provided between the two sheet metal elements (1, 2), the two sheet metal elements (1, 2) are fastened by depositing a weld bead (4) in the base of the joining face (3) in a discontinuous manner along said joining face (3), and then a clean material for forming a sealed joint (5) is deposited along the joining face (3) over the entire length of said joining face (3).
