Which arc welding process requires manually feeding a filler rod while creating a bead?

  1. MIG welding

  2. SMAW

  3. TIG welding

  4. Wire welding

The correct answer is: MIG welding

MIG welding stands for Metal Inert Gas welding, also known as Gas Metal Arc Welding (GMAW). In MIG welding, a wire electrode is continuously fed through a welding gun, which creates an electric arc that melts and fuses the base metals together. A shielding gas is also used to protect the weld pool from atmospheric contamination. Unlike SMAW (Shielded Metal Arc Welding) where the filler rod is manually fed, MIG welding does not require manual feeding of the filler rod. TIG welding (Gas Tungsten Arc Welding) also uses a non-consumable tungsten electrode and requires manual feeding of the filler rod. Wire welding is a broad term that can encompass various welding processes, including MIG welding.
