A weldable stud, especially one of high carbon steel to be drawn-arc welded to high or low carbon substrates (or vice versa), desirably includes a fluxing combination consisting essentially of nickel and aluminum. The conical end of the stud to be welded preferably has a hole in its tip for receiving a flux assembly wherein the nickel and aluminum respectively are present roughly on the order of about 30 to 70 percent by weight in novel and alternative forms for engendering austenitic joints. Resultant alloying at the fusion zone of the stud and substrate interfaces provides improved weld strength.
