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.
Gas metal arc welding (GMAW), also known as metal inert gas or MIG welding, is a semi-automatic or automatic process that uses a continuous wire feed as an electrode and an inert or semi-inert gas mixture to protect the weld from contamination.elding is a fabrication or sculptural process that joins materials, usually metals or thermoplastics, by causing fusion, which is distinct from lower temperature metal-joining techniques such as brazing and soldering, which do not melt the base metal.
