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.
The technical names for these are metal inert gas (MIG), and tungsten inert gas (TIG). A MIG welder works by using a continuously feeding spool of welding wire that burns, melts and fuses both the base and parent metals together. You can weld a variety of materials such as mild steel, stainless steel and aluminum.he most versatile machine is the TIG welder as you can weld many different types of metals. The downside is that it is very slow. For anybody wanting to do some welding at home your better choice of machine to buy would have to be the wire feeding MIG welder.
