Bumper beam with losing plate joined using CD welding (capacitor discharge)

摘要

The invention relates to a bumper bracket for a motor vehicle body, comprising a first profiled section having a three-dimensional structure and a second component, which spatially closes the first profiled section. The two components have overlapping surfaces used for welding, wherein the welding is carried out by way of impulse capacitor discharge welding.

主权项

1. A bumper bracket for a motor vehicle body, comprising:
a first profiled section having a three-dimensional structure; a second component, the first profiled section and the second component having spaced apart and distinct overlapping surfaces used for welding, wherein the second component closes the first profiled section between the spaced apart overlapping surfaces, wherein the welding is carried out as impulse capacitor discharge welding; and wherein of at least one if the weld seams extends in a longitudinal direction at least half the length of the first profiled section.
