Abstract:
Provided is an Ni-base alloy coated arc welding rod that exhibits an excellent resistance to moisture absorption by the coating agent and that can suppress blowhole production during welding. The Ni-base alloy coated arc welding rod has a core wire coated by a coating agent. The contents of SiO2, CO2, F, Ni, TiO2, and Al2O3 in the coated arc welding rod, with reference to the total mass of the coated arc welding rod, are controlled to provide prescribed ranges. In addition, the coating agent contains, with reference to the total mass of the coating agent, Li : 0.3 mass% to 1.2 mass%, Na : 0.5 mass% to 1.5 mass%, and K : 0.6 mass% to 1.8 mass%, and has [Li]/[K] of 0.15 to 1.4 where [Li] and [K] are, respectively, the Li content and K content in the coating agent as the mass% with reference to the total mass of the coating agent.
