Abstract
A flux-cored wire for stainless steel arc welding having flux filled up in an outer metal sheath made of stainless steel, comprises: as percentage to total weight of the wire, TiO2 5.5 through 10.0 mass %, SiO2 1.5 through 3.0 mass %, Al2O3 0.5 through 1.5 mass %, and fluorine compound (by a value expressed in terms of fluorine) 0.10 through 0.15 mass %, and an amount of ZrO2 is limited to no more than 0.1 mass %, and it has a flux rate of 25 through 45%, and a total amount of slag forming ingredient is 8 through 14 mass % as a percentage to total weight of the wire, and thereby to provide excellent welding workability especially in welding of a thin sheet stainless steel.
