The effect of replacing argon by nitrogen was investigated for the purÂ­pose of reducing welding costs. The study reveals that nitrogen can very well be used to replace argon for purging in pipe welding without any adverse effects on the properties of the unstabilized austenitic stainless steels.
Because helium is a very light gas, higher flow rates must be used for effective shielding. This characteristic is. beneficial in overhead welding. Carbon dioxide: is widely used for steels. Higher welding speed, better joint penetration and sound deposits with good. mechanical properties can be achieved. Carbon dioxide is not an inert gas as the argon and helium and breaks down. into carbon monoxide and free oxygen under the heat of the arc.
