Flux Cored Wire is the most widely used welding material for Flux Cored Arc Welding these days. This paper introduces the technical aspects of manufacturing FCW and the development trend of FCW for each type of steel and metal. The studies are ongoing to lower the production cost of seamless-type FC...

Flux Cored Wire의 장점은 무엇인가? | Flux Cored Wire(이하 FCW)는 Flux Cored Arc Welding(이하 FCAW)에 사용되는 용접재료로 Covered Electrode를 사용하는 Shield Metal Arc Welding (이하 SMAW)을 대체하기 위해 1953년 Arthur Bernard1)에 의해 개발 되어 현재는 가장 널리 사용되고 있는 용접 재료이다. 튜브(Tube) 내부에 플럭스(Flux)를 함유하여 반자동 및 자동 용접이 가능하고 높은 생산성과 이동성 때문에 다양한 산업분야에 사용된다. | |
FCW는 어떻게 구성되어 있는가? | FCW는 금속 외피 또는 튜브(Metal Sheath or Tube) 와 튜브 내부에 충전된 플럭스로 구성되어 있으며, 금속 튜브의 단면 모양이나 플럭스 조성에 따라 다양한 형태의 FCW의 제조가 가능하다. Fig. | |
FCW는 심부의 유무에 따라 어떻게 구분되는가? | 3). 이와 같이 U자에서 O자로 성형·생산되어 심부를 가지게 된 와이어를 Folded type 와이어라 하고, 심부를 형성하지 않거나, 용접에 의해 심부가 제거된 것을 Seamless(심리스) type 와이어라 한다(Fig. 4). |
