As we all are informed about. Welding is nothing but a frictional process that is used to join metals and thermoplastics by means of melting and fusing them as one with the help of some power supply. A substance called as the filler, more often than not the metal or plastic of molten condition is made use of in the process of welding to grasp and fuse the work pieces as one.

Welding is a process that needs an energy source and it can be done with any kind of different energy sources. Energy sources like that of the gas flame, electric arc, laser, electron beam, friction and ultrasound are the sources that are most commonly used in Welding. In fact he source that are to be used for welding purposes mostly depends up on the material and the output. Welding machines are categorized into a constant current or that of the constant voltage. CV machine is used by gas metal arc welding and flux-cored arc welding processes. A CC machine is used to count on a preset number of amps reaching the material being welded.
