There are a considerable number of welding processes that cover a vast range of metals and some nonmetals in most industries and applications. An excellent resource for welding information is The American Welding Society (AWS.org). A short list of the most common processes are: Oxygen Fuel Gas (OFG) which includes welding and cutting equipment where oxygen is mixed with a fuel gas such as acetylene, propane, etc. and a torch is used. Shielded Metal Arc (SMAW) sometimes called "Stick Rod" welding. This is a manual process that uses a flux covered wire electrode that melts during welding to form the filler metal. Gas Metal Arc Welding (GMAW) sometimes called "MIG" (for Metal Inert Gas) which is a semi automatic process that uses a bare or flux cored wire that is delivered by a spool drive during welding. Gas Tungsten Arc Welding (GTAW) sometimes called "TIG" (for Tungsten Inert Gas) or Heiliarc (trade name by the Lindy corp.) which uses a non consumable Tungsten electrode in an inert gas shielded gas torch. The Tungsten's produces the heat (via an electric current) and filler metal is added by "dipping" the tip of a bare wire to the weld puddle. The list goes on to include things like Electron Beam Welding , Plasma Arc Welding / Cutting, Friction Welding, Explosion Welding. Microwave Welding, Plastic Welding, etc.. Welding is used on everything from auto mufflers to space vehicles and medical instruments.

SAW welding is a type of arc welding while ERW welding is spot or seam welding. SAW stand for submerged arc welding while ERW stands for electric resistance welding.
smaw welding is sheilded metal arc welding
what is the difference between ultrasonic welding & radiographic welding
Mainly In spot welding & resistance welding two type welding machines are used :- 1. Air Cooled & 2. water Cooled.
Currently, there are a bunch of different kinds of welding jobs available to those who have the necessary training. If one has the training, do welding for some very prestigious companies. http://welding.jobs.topusajobs.com/

Stick welding machines are usually the least expensive machines available. Stick welding SMAW is used to fabricate steel and many other kinds of metals. A big variety of electrodes including cutting rods are available. This process is relatively easy to learn and use. From small farms to big industries to home workshops stick welding is the first choice from beginners to craftsmen.

The welding operation is stopped by moving the welding torch away from the workpiece to break the electrical circuit and extinguish the welding arc. Additionally, turning off the welding power source or releasing the welding trigger can also stop the welding operation.

CS Welding is known as Carbon Steel welding that is more beneficial and easy to use for welding purpose.
Digital Control of welding when welding
Welding Electrorodes or Welding Rods are used in arc welding. Arc welding is a special type of welding which uses a welding power supply to create an electric arc between the base material (e.g. steel) and the electrode. The Welding Ectrorodes can be used for all weldable aluminum and mild steel.
