Abstract

A method for manufacturing welded lap joints comprising the following steps: Providing of two components each having at least one base; allocating the components in such a way that the bases face each other and the components overlap in an overlapping area, which extends at least partially over both components; joining the components by welding in the overlapping area such that a weld joint is formed, wherein at the edge of the overlapping area non welded areas are formed; removing of the non welded areas whereby outer cutting areas are formed at the components, which are arranged at obtuse angles to the overlapping area.

Claims6

Dependent claims

A method for the production of overlapping weld joints comprising the following steps:

(a) provision of two components which are to be joined and each have a planar base material and at least one plateau-shaped elevation emanating from the planar base material;
(b) arrangement of the components such that the plateau-shaped elevations are contacting one another and the components overlap to form an overlap region;
(c) joining of the components by welding in the overlap region while forming at least one weld, wherein in the overlap region of the two components on both sides of the at least one weld a non-welded region is formed, wherein the two components overlap in the non-welded region and are not welded together;
and
(d) separating material from the two components to remove the non-welded regions to form outer cut edges on the components which are arranged at an angle to an edge of the overlap region in which the two components overlap and are welded together.
