Abstract
Arc welded joint between a carrier and a metal component with a continuous recess into which a stud-like weld-in part is introduced, wherein the weld-in part which consists of a shank and an enlarged head is pressed into the recess and 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, the pool of melt directly connecting the component to the adjacent carrier. 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.
Claims6
A method of connecting metal members via a welded joint comprising the steps of
- providing an assembly comprising a sheet metal carrier;
- a sheet metal component overlying said carrier, said component having a bore therethrough;
- and a plug comprising a head, said head being located partially within said bore and having a first surface facing said carrier and a second surface facing away from said carrier;
- establishing a welding arc within said bore;
- creating a pool of melt made up of material from said carrier, said component and said plug;
- plunging said plug into said pool to force material from said pool to flow out of said bore and over said second surface of said head;
- and
- allowing said pool to solidify.
