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
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
