Abstract
A component arrangement includes a first sheet metal profile part and a second sheet metal profile, each first and second profile parts having respective flanges and being arranged relative to each other so that the respective flanges overlap, wherein the first and second profile parts are connected to each at the respective flanges via a laser welding connection, which extends over a welding seam length, wherein the laser welding connection is formed by at least two welding seams which extend parallel and at a distance to each other.
Claims10
A method for producing a vehicle door, comprising:
- providing a first sheet metal profile part and a second sheet metal profile part, each having respective flanges;
- arranging the first and second sheet metal profile parts relative to each other so that the respective flanges overlap;
- connecting the first and second sheet metal profile parts to each other at the respective flanges via a laser welding connection, which extends over a welding seam length, said laser welding connection being formed by at least two welding seams which extend parallel and at a distance to each other, wherein the at least two welding seams are configured as stitch-welding seams which are formed by segments which are spaced apart in a welding processing direction via gaps, and
- generating the at least two welding seams in separate temporally subsequent process steps.

A component arrangement, comprising:
- a first sheet metal profile part having an end forming a border flange protruding laterally outward;
- a second sheet metal profile part having an end forming a border flange which protrudes laterally outward and is sized to overlap the border flange of the first sheet metal profile part along a lap joint region in substantial parallel relationship, said first and second sheet metal profile parts defining inner and outer sheet metal profile parts and together forming a hollow profile;
- and
- a laser welding connection connecting the border flange of the first sheet metal profile part with the border flange of the second sheet metal profile part within the lap joint region, said laser welding connection being formed within the lap joint region by at least two stitch-welding seams which extend parallel and at a distance to each other and are formed by seam segments which are spaced apart in a welding processing direction via gaps.
