FLUX CORED WIRE FOR GAS SHIELDED ARC WELDING AND GAS SHIELDED ARC WELDING METHOD

摘要

Containing wire and gas shielded arc welding method for gas shielded arc welding which can obtain a good bead shape in horizontal fillet welding with a large leg length without increasing the amount of welding slag. The flux-containing wire for gas shielded arc welding is characterized by satisfying the following formulas (1) to (4) when the viscosity of the slag after welding is represented by p [Pa · s] and the solidification temperature is Ts do.
