FLUX CONTAINING WIRE FOR USE IN STAINLESS STEEL WELDING

摘要

Described herein is a flux cored wire for use in stainless steel welding, the wire having a flux filled in a stainless steel sheath, the flux containing, on the basis of the total weight of the wire, 4.7-8.5% of TiO2, 0.5-3.5% of Al2O3 and 0.6-3.0% of SiO2 and/or ZrO2 in proportions satisfying the following formula TiO2 > Al2O3 + SiO2 + ZrO2 and further 0.02-0.25% of metal fluoride (in terms of F conversion value) and 0.1-1.0% of Ti. Desirably, the flux contains slag-forming components in a restricted range of 8.5-13.5% and in proportions satisfying the following formula Al2O3 + SiO2 + ZrO2 ~ 5.0%.
