There's some information on welding at http://www.WeldingFun.com .. should have the answer your looking for. Sorry for being to lazy to look it up
If by gas welding you mean-oxyacetylene welding. The difference is just that arc welding requires a darker shade of lens. When oxyfuel gas welding (OFW) usually a shade 5 lens is recommended. When arc welding, a minimum of shade 10 lens should be used (actually shade should be determined by amount of current used).
tungsten inert gas metal inert gas now refered to as gmaw gas metal arc welding.

shielded metal arc welding does not required any shielding gas
The gas metal arc welding that is also called the metal inert gas. It is a welding process whereby the electric arc forms between the work piece metals and the consumable wire electrode.
The difference between a gas and a plasma is the chemical properties. Plasmas collect electric currents and electric and magnetic fields affect plasmas
Larger in Gas Welding. In all arc processes the HAZ is concentrated in a couple inches around your bead. In gas welding it can be double or triple that size.
Some methods are used: - electron beam welding - laser beam welding - gas wolfram arc welding - gas metal arc welding - resistence welding - brazing
Lincoln Electric is a renowned leader in welding products and services. These services include pipe welding, gas tungsten arc welding, gas and metal arc welding.
Both.
GAS TUNGSTEN ARC WELDING
There are far more than 5 types or processes of welding. Currently the American Welding Society (AWS) states that there are more than 80 different welding and joining processes. However, some of the common welding processes include shielded metal arc welding (SMAW), gas metal arc welding (GMAW), gas tungsten arc welding (GTAW), flux cored arc welding (FCAW), and oxyfuel gas welding (OFW).
