Title: FLUX-CORED WIRE FOR GAS-SHIELDED ARC WELDING
Abstract:
Provided is a flux-cored wire for gas-shielded arc welding that contains, per wire total mass, specific amounts of C, Mn, TiO2 and specific amounts or less of P and S, and contains, in the flux, a specific amount of Ni per wire total mass. The Ni has a ratio (α1/α2) of 0.50-1.00 when α1 (mass%) is the content per wire total mass of particles having a size of 106 μm or less and α2 (mass%) is the content per wire total mass of particles having a size exceeding 106 μm.
