Abstract:The Ni-Cr-B-Si-W alloy wires for oxy-acetylene flame welding were produced using a special pro-cess. Particularly the significance of each element added to the wires and the effect of alloying elements on bead-on-plate test were studied. In addition,an alloy wire for oxy-acetylene flame welding, named type-112, was picked out to be used for overlay welding,making the bead welding possess superior hardness.
Key words: wires for gas welding overlaying weld hardness
