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.
Gases given off by the welding process can also be extremely dangerous. For example, ultraviolet radiation given off by welding reacts with oxygen and nitrogen in the air to form ozone and nitrogen oxides. These gases are deadly at high doses and can also cause irritation of the nose and throat and serious lung disease.
