PROBLEM TO BE SOLVED: To provide excellent welding workability even when Ca, Al, Mg, Ti or the like which can be the cause of the slag oxide are slightly contained by complexly adding each slag component of the prescribed quantity. SOLUTION: A gas metal arc welding wire for austenitic stainless steel has the composition consisting, by weight, 0.008-0.15% C, 0.2-1.0% Si, 1.0-3.0% Mn, 11-32% Cr, 3.0-22.5% Ni, 0.001-<=4% Mo, <=0.25% N, <=0.005% Ca, (Ca×(1-2)+0.001)% Al, <=0.015% S, <=0.01% O, <=0.005% Mg, and the balance Fe with inevitable impurities. The wire of excellent welding workability can be obtained even when the slag oxide is generated in the gas metal arc welding wire in TIG welding and MIG welding by this composition, and a weld zone of excellent quality can be obtained as a result.
