Summary: | The invention discloses a surfacing process method for a wear-resistant belt of a titanium alloy drill rod joint. The surfacing process method comprises the following steps: (1) pretreating the surface of the titanium alloy drill rod joint; (2) preheating a welding area of the wear-resistant belt of the titanium alloy drill rod joint; (3) surfacing a nickel-based welding material wear-resistant belt on the titanium alloy drill rod joint by adopting a TIGer double-tungsten-electrode hot wire argon arc welding process method; (4) annealing the surfacing layer of the wear-resistant belt of the titanium alloy drill rod joint; and (5) post-treatment. According to the method, a TIGer double-tungsten-electrode hot wire argon arc welding process method is adopted, the nickel-based welding material and the titanium alloy drill rod joint are fused with each other through stable molten pool temperature control, the dilution rate of the welding material and a base material and the deposition rate of the welding material |
