LIMITATIONS OF GAS TUNGSTEN ARC WELDING (GTAW)

It Produces lower deposition rates than consumable electrode arc welding processes.
It Requires slightly more skill as compared to MIG or Shielded Metal Arc Welding (SMAW).
Less economical for very thick sections more than 9.5 mm.
Problematic in drafty environments as difficulty in shielding the weld zone properly.

Additional problems with the process may include following points:

Tungsten inclusions if the electrode is allowed to contact with the weld pool.
Contamination of weld metal, if proper shielding of the filler metal by the gas stream is not maintained.
Low tolerance of contaminants on filler or base metals.
Arc blow or arc deflection like with other processes.
