What are some Limitations of Flux Cored Welding?

  • Presently limited to welding ferrous metals and nickel-based alloys
  • Process produces a slag covering that must be removed
  • Flux Cored Welding electrode wire is more expensive on a weight basis than solid electrode wires, except for some high alloy steels
  • Equipment is more expensive and complex than required for Stick Welding; however, increased productivity usually compensates for this
  • In general, more fume is generated than with MIG welding
