ABSTRACT:
A web seam for sheet metal parts and a process for producing the same wherein the web seam is provided with a triple layer web projecting from a surface of the sheet metal parts, the layers are formed from a first flange of one sheet metal part and a second flange of the other sheet metal part. The first flange and a portion of the second flange immediately adjoining the other sheet metal part are separately connected by spot welds or by cementing in an intermediate step. The projecting edge of the second flange is then folded over in a U-shape and extends over the first flange. Additional weld spots or cement are applied to the web seam, which weld spots or cement simultaneously cover all three layers. A bight portion joining the first leg and a second leg of the U-shaped flange has a bending diameter which is larger than a single thickness of the sheet metal and, preferably, is twice the sheet metal thickness.
