Welding is the fusing of to metals, but the term "fusing" in a welding shop is the melting together of to materials without using filler rod. Usually done with a TIG Machine. The process results in a small weld, that does not need to be ground flush, because it already is. The only problem is that a "fused" weld isn't as strong.

there is no difference between this two...

what is the difference between ultrasonic welding & radiographic welding
Welding involves melting and fusing two metal pieces together, creating a strong bond. Soldering, on the other hand, uses a lower melting point material to join two metal pieces, creating a weaker bond.
The prehaet temperature is taken before welding starts. The interpass temperature is taken between welding passes.
back hand welding is when you pull the welding rod or whatever it is that you are using and forehand is when you push it ahead
"Automotive" means that such a person is specialized in cars.
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.
Fusion welding joins materials by melting them together, while non-fusion welding joins materials without melting them. Fusion welding includes processes like MIG, TIG, and arc welding, where a filler material may be added. Non-fusion welding methods, such as friction welding or ultrasonic welding, rely on pressure or friction to create the bond between materials.
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
The main difference between these two types of welding is that GTAW uses gases to create the weld whilst SMAW uses an an electrical current. Both are very popular welding processes.
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).

EFW: Electric Fusion Welding is a more general term which includes Electric resistance welding (ERW) and other types of welding such as Arc welding.
