A method of joining sheet metal parts is disclosed which includes forming tabs on one and slots in the other of a pair of parts being welded together with the tabs having a length equal to half the dimensional thickness of the parts. The tabs fit accurately within the slots and welding takes place within the slots at the ends of the tabs so that the heat generated by the welding process and the weld material deposited are located in the neutral axis of the parts being joined together so that distortion of the parts due to the welding process is lessened or eliminated.
Méthode pour assembler des éléments de tôle dans laquelle on forme des pattes sur l'un et des encoches dans l'autre de deux éléments qu'on soude ensemble, les pattes formées ayant une longueur égale à l'épaisseur de l'ouvrage construit avec ces éléments.Les pattes s'insèrent avec précision dans les encoches et le soudage se fait à l'intérieur des encoches à l'extrémité des pattes de sorte que la chaleur générée par le soudage et le métal d'apport se situe dans l'axe neutre des éléments assemblés et, conséquemment, la distorsion des éléments par suite du soudage est diminuée ou éliminée.
