| description | The invention discloses a solid welding wire for submerged-arc welding of a pure solid solution strengthened heat-resistant alloy C-HRA-2, and belongs to the technical field of heat-resistant alloy welding materials. The solid welding wire is prepared from, by weight, 0.06-0.12% of C, less than or equal to 1.0% of Si, less than or equal to 1.0% of Mn, less than or equal to 0.015% of P, less than or equal to 0.001% of S, 20-22% of Cr, 10-13% of Co, 8.1-8.8% of Mo, 0.1-1.0% of W, less than or equal to 0.0025% of N, less than or equal to 0.0025% of O, less than or equal to 0.1% of Fe, and the balance of Ni and inevitable impurity elements. The solid welding wire has the advantages that the thermal crack resistance sensitivity is improved by 90%, the welding strain aging cracks of the alloy are fundamentally eliminated, the manufacturability of the welding process is good, slags are easy to remove, formed welding seams are attractive, and the surface is free of defects of bonded slags, pits and the like.
