The composite weld wire includes an inner core wire and surface a layer applied and bonded to the inner core wire. The surface layer includes alloying elements selected from among B and Si with total bulk content a of B and Si in the composite welding wire of 0.1 to 10 wt. %. Preferably the total bulk content of B is less than 4 wt. % and the sur­ face layer comprises from 5 to 95 wt.% of the alloying ele­ ments selected from among B and Si.
