PURPOSE:To obtain a composite wire for welding that makes the packed flux difficult to absorb moisture by joining the butted metal outer cover containing welding flex length-wise and continuously by a laser. CONSTITUTION:Laser light 5 is irradiated lengthwise and continuously on the butted part 3 of a metal outer cover 1 containing flux 2. As the result, the butted part 3 is joined partially or wholly in the direction of thickness to form a laser joint 4. |
