The invention relates to a method of assembling two sheet metal elements (1, 1′), involving applying a bead of adhesive to a first element, assembling the second sheet metal element on the first and securing it by spot welds to hold the two sheet metal elements stationary before curing the adhesive. The invention consists in the fact that the bead of adhesive is applied discontinuously to the first sheet metal element (1) along an adhesive line and then, once the second sheet metal element (1′) has been pressed against the first, the two elements (1, 1′) are held fixed together by creating spot welds on sections of the discontinuous adhesive line that are devoid of adhesive.

A different material joining method sandwiches, with electrodes, a first joining member and a second joining member lower in melting point than the first member, applies pressure and electricity to them, and joins them in preset joint parts. The method includes forming a discontinuous abutting part beforehand in the joint part of at least one of the two members. The two members abut onto the abutting part in a discontinuous state. The method includes melting the second member by sandwiching the joint parts with the electrodes and applying pressure and electricity on the joint parts in a state where the two members abut onto each other in the joint parts while the abutting part is included. The method includes welding both the members by bringing a melting material of the second member into interface joining with a surface of the first member toward the second member.
