摘要

This flux cored wire contains CaF2 and the like with the total content α of CaF2 and the like being 3.3-6.0% by mass relative to the total mass of the flux cored wire; contains Ti oxide and the like with the total content &bgr; of Ti oxide and the like being 0.4-1.2% by mass relative to the total mass of the flux cored wire; and contains CaCO3 and the like with the total content of CaCO3 and the like being 0.1-0.5% by mass relative to the total mass of the flux cored wire. The content of iron powder in the flux is less than 10% by mass relative to the total mass of the flux cored wire.
