ABSTRACT:
Arc welded joint between a carrier such as aluminium sheet as one electrode and as the other electrode a metal component with a continuous recess into which a stud-like weld-in part is introduced, wherein the weld-in part consists of a shank and a head which is enlarged in relation to the shank diameter via a step, penetrates into the recess in the component resting on the carrier and can be pressed into the pool of melt formed on the carrier so that the pool of melt adjacent to the wall of the recess embraces the outer rim of the head and the step, the pool of melt directly connecting the component, at least in the region of the edge of the wall of the recess facing the carrier, directly to the adjacent carrier. The outer rim of the weld-in part may protrude slightly beyond the component and penetrate into the recess with a projection or step such that, remote from the carrier, it can be pressed into the pool of melt to cover the entire wall of the recess including its two edges to its outer rim as well as the carrier and the head. The rim of the head may be designed as a radial melting edge which is located completely within the recess of the component and has a substantially blade-like cross section.
