Working principles of flux cored arc welding FCAW

Unlike other arc welding process that uses AC or DC power supply, FCAW supplies power from DC electric arc to the welding gun. The arc is produced when the gun is struck between the continuously fed consumable filler wire and the workpiece. It creates the weld pool and bonds when the pool solidifies.

Advantages

The following are the advantages of FCAW;

  • It has different ways of supplying shielding gas
  • It may be applied to all welding position
  • Shielding gas is not needed for some of its wires are suitable in windy conditions
  • It has a high deposition rate
  • Chances of porosity are very low
  • Less cleaning of base metal

Disadvantages

Despite the great benefits of FCAW, it still offers some disadvantages. The following are the limitations of this welding process.

  • It produces slag, which must be removed after welding
  • It produces more smoke which is hazardous to the welder
  • Cost of applied wire
  • It Is complex and more expensive
  • It produces more spatter
