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.
