<p>Provided is a vertical-up type gas shielded arc welding method which has excellent arc stability and obtains good bead shape with one pass at the same time during a vertical-up type fillet welding wherein the leg length is 5.0 mm or less. The vertical-up type gas shielded arc welding method using a titania based flux cored wire for gas shielded arc welding uses the titania based flux cored wire for gas shielded arc welding which contains TiO_2 of 4.5-8.0 wt% for a total mass of wire, a welding condition whereby a torch is inclined at an angle of 55-85°, and a welding current of 100-180 A with a wire protruding length of 5-30 mm.</p> |
