  • Slide 1

Flux Cored Arc Welding (FCAW) Slide 2 Linnert, Welding Metallurgy, AWS, 1994 Slide 3 FCAW Electrode Classification E70 T - 1 Electrode Minimum UTS 70,000 psi Position Flux Cored /Tubular Electrode Type Gas, Usability and Performance Flux-Cored Arc Welding American Welding Society Specification AWS A5.20 and AWS A5.29. Slide 4 Linnert, Welding Metallurgy AWS, 1994 Slide 5 Advantages High deposition rates Deeper penetration than SMAW High-quality Less pre-cleaning than GMAW Slag covering helps with larger out-of- position welds Self-shielded FCAW is draft tolerant. Flux-Cored Arc Welding Slide 6 Limitations Slag must be removed More smoke and fumes than GMAW and SAW Spatter FCAW wire is more expensive Equipment is more expensive and complex than for SMAW Flux-Cored Arc Welding
