Advantages of TIG Aluminium Welding

Gas Metal Arc Welding (GMAW) and Gas Tungsten Arc Welding (GTAW) are suitable for aluminum welding. Aluminum alloy castings need the same technique applied to aluminum sheets and many different wrought products. Many castings are vulnerable to thermal strains because of delicate designs and varying cross sectional areas. Sometimes aluminum alloy castings need heat treatments before welding. TIG Aluminum Welding is very much common in welding aluminum castings. But sometimes welding contributes in the destruction of the effect of initial heat treatment. In those cases it is highly recommended to heat treat the metal after welding. In this article we will discuss about the advantages of tig aluminum welding .

TIG Aluminum Welding Benefits 

  • One of the many advantages of TIG aluminum welding is it eliminates the requirement of flux. As a result the welding is free from a source of corrosion. 
  • Welding can be done in any position. TIG welding also gives better visibility and high speed welding can be performed. 
  • Pressure tight joints can be got with very low distortion and high strength. 
  • GTAW is relatively easy to perform and it is a high speed welding technique. It is one of the reasons that TIG is preferred over other fusion welding methods. 
  • TIG welding uses non-consumable electrodes and AC current. Argon or Helium is used as the inert shielding gas. If filler material is needed then it can be fed automatically or manually. 
  • Very thin aluminum (0.6 mm 0r 0.025 inches) can be welded but materials having thickness of 1 mm or more give good results. 
I think now you know why tig aluminum welding is used .
