Flux Core Arc Welding in Refinery Service - Historical Obstacles, Industry Practices, Recent Developments

Richard Colwell and Bill Layo, Bechtel Corp

Stigmatized by early quality problems in the 1970’s and 1980’s, Flux Cored Arc Welding (FCAW) has evolved into a process by which experienced fabricators can obtain radiographic quality welds in many alloy systems.  Research and development have produced consumables for gas-shielded procedures that can meet many refinery industry specifications. While there is reluctance on the part of some owners to accept FCAW (g), today’s competitive market has enabled fabricators to persuade some segments of the petroleum processing industry to accept FCAW(g),  for pressure vessel, heat exchanger, and piping fabrication applications in order to reduce both cost and schedule.
