Abstract
본 발명은 고열전도성 석출경화형 CuCrZr 구리합금을 멀티-패스 미그 용접하는 방법에 관한 것으로, 본 발명에 의하며, 고열전도성 석출경화형 CuCrZr 구리합금 모재의 멀티-패스 미그 용접에서 용접전류는 290~320A, 전압은 30~32V, 예열온도는 400~430℃, 분위기 가스는 Ar와 He의 혼합가스를 사용함으로서 고강도와 양호한 도전성 및 열전도성을 가지며 블로홀등의 용접결함이 거의 발생하지 않음은 물론 고온사용시에도 중간 온도취성의 발생이 거의 없는 용접부를 형성할 수 있다.The present invention relates to a method for multi-pass MIG welding of high thermal conductivity precipitation hardening CuCrZr copper alloy, and according to the present invention, the welding current in the high thermal conductivity precipitation hardening CuCrZr copper alloy base material is 290 ~ 320A, voltage Silver 30 ~ 32V, Preheating temperature is 400 ~ 430 ℃, Atmospheric gas is mixed gas of Ar and He, high strength and good conductivity and thermal conductivity. It is possible to form a welded part with little occurrence of temperature brittleness.
