ABSTRACT:
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 tabs and material bordering the slots are melted together with the welding rod or wire, whereby the heat generated by the welding process and the resultant weld material 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.
