（Department of Mechanical Engineering, Xiangtan University，Xiangtan 411105）
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
