The difference between a gas and a plasma is the chemical properties. Plasmas collect electric currents and electric and magnetic fields affect plasmas
well plazma is created when an arc becomes such an intence heat that it creates a flame like in a plazma cutter and gas well is from a balance between a flamable and oxygen.

Tungsten Inert Gas (orTIG) welding is also referred to as GTAW (Gas Tungsten Arc Welding) and by the term Heliarc® which was the Linde Company's trade name for the TIG process when it was originally introduced.The welding arc is started with a sharply pointed tungsten electrode shielded by inert gas. A separate filler rod is fed manually into the weld puddle in much the same way as is done when gas welding.The process is well suited for aluminum.
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
the difference between plasma and the other states of matter is that,plasma is an ionized gas.
The difference between gas and plasma is the physical structure. The gas turns into a plasma when the gas becomes ionized and loses its positively charged particles. They are similar because they both have no definite shape, but plasma responds strongly to magnetic fields and also emits 5x the electricity it puts in.
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).
lava is the molten form of rocks and plasma is a ionized form of gas.
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

A gas is composed of atoms (noble gases) and molecules, such as oxygen gas. Plasma is composed of positively charged ions and unbound electrons.
tungsten inert gas metal inert gas now refered to as gmaw gas metal arc welding.
Shielded welding needs a gas to shield the weld from the atmoshere air. Unshielded uses a flux the burns when welding to shield the weld from the atmoshere air.
Plasma only occurs at very high temperatures.
Heat in plasma arc welding (PAW) transferred arc mode is generated by the arc that is established between the electrode and the workpiece. The orifice gas inside the constricting nozzle is then heat and ionized by the arc. The ionized gas is in the form of plasma and is sent out of the constricting nozzle in a concentrated, cylindrical shape. Thus, creating temperatures greater than 10000 degrees Celsius. This process is very similar to gas tungsten arc welding (GTAW).
