Abstract: 동축 전력 피드를 갖는 전극들(100)의 실시예들을 사용하는 용접 방법이 제공된다.  전극은 중공 코어(110)를 정의하는 금속 실린더(105)를 포함한다.  중공 코어는 전달 수단(200)에 의하여 이 중공 코어 사이에 코어 피드 재료들(150)을 전달하기 위한 도관을 제공한다.  실린더가 원하는 초합금 재료 조성을 형성하기 위한 순수 금속들 또는 압출성 합금들로 형성될 수 있는 한편; 전달되는 코어 피드 재료들은 원하는 초합금 재료 조성을 형성하기 위한 조성 구성성분들의 잔부를 포함한다.  결과적 증착물은 적어도, 실린더 재료들과 코어 피드 재료들의 결합의 결과로서 원하는 초합금 조성을 달성한다.  전극은 실린더를 둘러싸는 플럭스 코팅(120)을 더 포함할 수 있다.  플럭스 재료는 또한, 용접 동작의 결과로서 원하는 초합금 조성에 기여할 수 있다.
