For which welding process is a continuously fed consumable wire used?

  1. FCAW

  2. GTAW

  3. MIG

  4. TIG

The correct answer is: FCAW

In the FCAW (Flux-Cored Arc Welding) process, a continuously fed consumable wire is used. This wire contains a flux core, which protects the molten weld pool from atmospheric contamination. Option B (GTAW - Gas Tungsten Arc Welding) and Option D (TIG - Tungsten Inert Gas Welding) both involve the use of a non-consumable tungsten electrode, where the filler material is manually added to the weld joint. Option C (MIG - Metal Inert Gas Welding) is very similar to FCAW, but in MIG welding, a solid wire electrode is typically used along with a separate shielding gas.
