Title: FLUX-CORED WIRE FOR GAS-SHIELDED ARC WELDING
Abstract:
Provided is a flux-cored wire for gas-shielded arc welding that contains specific amounts of C, Mn, TiO2, and Ni and specific amounts or less of P and S. The TiO2 has a ratio (α1/α2) of 0.90-1.50 when α1 (mass%) is the content per wire total mass of particles having a size of 106 μm or smaller and α2 (mass%) is the content per wire total mass of particles having a size exceeding 106 μm.
