Carbon, low
0,9 ÷ 1,1
alloy steel
Aluminium 0,8 ÷ 1,6
Austenic
0,8 ÷ 1,6
stainless steel
Copper alloy 0,9 ÷ 1,6
Magnesium 1,6 ÷ 2,4
Tig Process:
In TIG welding process, gas usage depends on cross-sectional area of the nozzle. For commonly 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.
