摘要
采用特殊的方法制取镍铬硼硅钨气焊丝，着重研究了各元素在焊丝中的作用及对堆焊工艺性能的影响。筛选出１１２号气焊丝，用于氧－乙炔火焰堆焊，堆焊层具有较高的硬度。
The Ni-Cr-B-Si-W alloy wires for oxy-acetylene flame welding were produced using a special process.Particularly the significance of each element added to the wires and the effect of alloying elements on beadon-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.
