A stainless steel flux-cored welding wire for zinc - coated steel sheet welding use which gives a weld zone5 where no zinc embrittlement cracking occurs and the corrosion resistance and ductility are excellent andwhich is good in weld work efficiency and a welding method using the same, the welding wire characterized in that total amounts of elements which are included as10 metals or alloy compositions in the sheath and flux are, by mass% with respect to a total mass of the welding wire, C: 0.01. to 0.05%, Si: 0.1. to 1.5%, Mn: 0.5 to 3.0%, Ni: 7.0 to 10.0%, and. Cr: 26,0 to 30.0%, an F value i5 30 to SO in range, further, the wire contains, as slag15 forming agents, in. the flux, by mass% with respect to the total mass of the wire, TiC2: 3.8 to 6.8%, SiO2: 1.8 to 3,2%, Zr02: 1,3% or less, and 7k1203: 0.5% or less, a total amount of the slab forming agent and other slag forming agents is 7.5 to 10,5%, furthermore, the TiO2 satisfies,20 by mass% with respect to the total amount of. slag forming agents, TiO2.: 50 to 65%, and a balance of the sheath and flux. is Fe and unavoidable impurities. |
