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.
For stainless steels there are also gases available containing small amounts of hydrogen (H 2). The table indicates the appropriate choice of shielding gas for MIG/MAG welding, taking account of different types of stainless steel and arc types.or stainless steels there are also gases available containing small amounts of hydrogen (H 2).
