본 발명은 초내열합금으로 제작된 부품들의 용융 용접을 위한 복합 용접 와이어이다. 복합 용접 와이어는 내측 심선과, 내측 심선에 도포되고 결합된 표면층을 포함한다. 표면층은 B 와 Si 중에서 선택된 합금 원소를 포함하는데, 복합 용접 와이어 중의 B 와 Si의 총 벌크 함량은 0.1 내지 10 중량%이다. 바람직하게는 B 의 총 벌크 함량은 4 중량% 미만이며, 표면층은 B와 Si 중에서 선택된 5 내지 95 중량%의 합금 원소를 포함한다. The present invention is a composite welding wire for fusion welding of components manufactured of superalloys. The composite weld wire includes an inner core wire and a surface layer applied and bonded to the inner core wire. The surface layer includes alloying elements selected from among B and Si with a total bulk content of B and Si in the composite welding wire of 0.1 to 10 wt. %. Preferably the total bulk content of B is less than 4 wt. % and the surface layer comprises from 5 to 95 wt. % of the alloying elements selected from among B and Si.
