A stainless steel flux-cored welding wire for the welding of galvanized steel sheets, which dose not cause zinc embrittlement cracking, can give welds excellent in corrosion resistance and ductility, and attains excellent workability in welding; and a process for welding with the same. The welding wire is characterized in that the sheath and the flux contain, as metal or alloying components and in a total amount based on the total mass of the wire, C: 0.01 to 0.05%, Si: 0.1 to 1.5%, Mn: 0.5 to 3%, Ni: 7 to 10% and Cr: 26 to 30% with the F value falling within the range of 30 to 50, that the flux contains, as slag formers, TiO2: 3.8 to 6.8%, SiO2: 1.8 to 3.2%, ZrO2: 1.3% or below, and Al2O3: 0.5% or below, that the total amount of these slag formers and the other slag formers is 7.5 to 10.5%, that TiO2 accounts for 50 to 65% of the total amount of all the slag formers, and that the balance of the sheath and the flux consists of Fe and unavoidable impurities. |
