An outline on Flux cored arc welding
For flux cored arc welding, wire fed machines are used. The metals that are to be joined are melted first and then joined with the help of a consumable electrode that is continuously fed.
This process will require a constant voltage or a constant electric current. The flux core wire that is being used will also decide what type of external shielding gas is being used. This process is generally used for welding think sections and works great on welding oxidized materials.
The filler material for such welding process is usually costly. This is why it is not generally used for automotive works. This process is generally recommended for stainless steel and rusted materials. The advantage of this welding is the high speed of weld that it offers.
It can be used to get the job done quickly. Also portability is another asset of this kind of welding. This process is also very popular in constructions.
