Tig Process: 

 
In TIG welding process, gas usage depends on cross-sectional area of the nozzle. For comonnly used torches: 
 
Helium: 14-24 l/min 
Argon: 7-16 l/min 
 

Notice:

 Excessive flow rates causes turbulence in the gas stream which may aspirate atmospheric contamination into 

the welding pool. 
 

Notice:

 A cross wind or draft moving can disrupt the shielding gas coverage, in the interest of saving of protective gas 

use screen to block air flow.
