KEY TERMS. carbon flux Cored arc Welding self-shielding cast (FCAW) slag deoxidizers forehand smoke extraction deposition rate helix nozzles dual shield lime-based flux electrode feed systems rutile-based flux INTRODUCTION. The flux Cored arc Welding (FCAW) process has become extremely popular for Welding fabrication. Its popularity is due in part because of its portability, versatility, ease of use, and lower Equipment cost. In 2005, it passed the 50%. mark for all Welding production, and it is still rising. The introduction of small welders, some weighing less than 30 lb ( kg), has made FCA Welding a very portable process.
