I was taught that soldering,as it relates to piping, is the heating of the base metal to a point to where the filler metal will melt and fill the gap between the two pieces of metal being soldered. The base metal is NOT melted, only the filler metal. Soldering is usually used to join non-ferrous metals. Welding is when the base metal is heated to a point where it will melt and , with the filler metal, becomes part of the weldment. In other words, the two pieces become one, and the resulting weld is now a blend of base metal and filler metal.
soldering is a very low heat (melting temperature of the soldering alloy is less than 840 degrees Fahrenheit), semi-adhesion process, final product: 2 base materials, and a filler material on top. welding is high heat fusion process, final product: a solid blended material
what is the difference between ultrasonic welding & radiographic welding
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.
EFW: Electric Fusion Welding is a more general term which includes Electric resistance welding (ERW) and other types of welding such as Arc welding.

The prehaet temperature is taken before welding starts. The interpass temperature is taken between welding passes.

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 best grade of aluminum for TIG welding is typically 5XXX series, specifically 5052, 5083, or 5086. These grades offer good weldability, strength, and corrosion resistance, making them ideal for TIG welding applications.
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).
what is the difference between 7018 and 7018-1
EFW: Electric Fusion Welding is a more general term which includes Electric resistance welding (ERW) and other types of welding such as Arc welding.
The only difference between the two is that projection welding requires preparation of the joint members in the way of adding a preformed dimple or projection. Spot welding is used without such preparation to the joint members. it's just heat and pressure.
