advantages

Flux-Cored Arc Welding

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.
limitations

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
