Gas metal arc welding (GMAW), sometimes referred to by its subtypes metal inert gas (MIG) welding or metal active gas (MAG) welding, is a welding process in which an electric arc forms between a consumable wire electrode and the workpiece metal(s), which heats the workpiece metal(s), causing them to melt, and join.
ï· âSâ stands for a solid wire. Since the wire is solid it always needs a form of shielding gas. ï· â 2 â represents the amount of cleaner that is added to the wire to improve weld quality. If you have MIG welded before, these designations might sound similar. The filler wires for MIG can also be used for TIG welding.astelloy 10. Titanium The TIG welding process can weld many more metals and alloys. On top of that, it can also weld many dissimilar metals together. Power Supply and Equipment The power supply used for TIG welding is a CC or âonstant urrentâ power supply just like Stick welding.
