Abstract
A weld-on part made of aluminum or an aluminum alloy, such as but not limited to a stud (), which has a surface which is at least partially provided with a layer () which contains a titanium containing material. The stud () is treated with a chrome-free passivating solution which imparts corrosion resistance while simultaneously causing a layer () of titanium containing material to be formed on at least a portion of the surface of the stud (). The layer () of titanium containing material permits the stud () to be satisfactorily welded to a surface, without the occurrence of arc jumping or blowing, in part, by lowering contact resistance during the welding process.
