摘要
PROBLEM TO BE SOLVED: To provide a filler wire for laser welding wire feed for an aluminum alloy which can suppress the occurrence of pores even in the case of welding an aluminum alloy member, particularly, a diecast molding of an aluminum alloy, to provide a welding method for an aluminum alloy using the filler wire, and to provide a welded member made of an aluminum alloy which is obtained by being welded by using the filler wire, and is provided with a sound weld zone having little deterioration in joint strength. SOLUTION: When the content of gaseous hydrogen in an aluminum alloy as the material to be welded is defined as X cc/100 gAl, the content Y% (mass ratio) of an Al-K-F based flux material in the filler wire for laser welding wire feed for the aluminum alloy is controlled so as to satisfy the conditions of 1.5X-1.5=Y=2.0X, and Y=0.
