ABSTRACT:
A connection of an outer sheet metal member with an inner sheet metal member whereby the outer sheet metal member must form an optically smooth surface. For that purpose, the outer sheet metal member is folded over the inner sheet metal member and a welding seam is then made from the folded-over side by means of a low energy welding process, for example, special forms of the protective gas welding or energy beam welding, and more particularly in such a manner that only the folded-over part of the outer sheet metal member and the inner sheet metal member fuse. The non-folded-over side of the outer sheet metal member thereby shows no impairment whatsoever by the welded connection.
