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.
The difference between a shogun and a samurai is like the difference between a king and a knight.
there is no difference between this two...
A question about "the difference between" requires two objects!
Explain the difference between the vassals and the serfs
the difference between a number and 3 is
what is the difference between ultrasonic welding & radiographic welding
Fusion is the blending of elements and can only be achieved by melting. Welding by definition is fusion. Brazing ,soldering etc are non fusing.
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.
in arc welding only heat is used to weld metal. but in resistance welding pressure will also be used along with heat.
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.
A red star is fusing mostly hydrogen while a blue star has depleted its hydrogen supply and is fusing helium into heavier elements.
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).
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.
