摘　　要：从降低硬质合金的烧损和沉淀出发研制了碳极氩气拘束电弧焊炬用以WC颗粒堆焊,结果表明所设计的焊炬堆焊WC颗粒可明显降低硬质合金颗粒的烧损和沉淀。The welding torch of carbon-electrode arc constrained by argon is made for bead welding of WC grain in order to decrease the burning and depositing of hard metal alloys. The result shows that the burning and depositing of hard metal alloys can be.decreased obviously in bead welding of WC grain by this welding torch.
