Plasma Arc Welding
> It is an arc welding process similar to gas tungsten arc welding
> An electric arc is formed between electrode and the work piece
> The plasma is forced through a fine bore cu nozzle which make narrower the arc and the plasma exists orifice at higher velocity approximately the sound of light at a temperature of 28000degreeC.
Plasma arc
> Arc plasma is the temporary state of a gas.
> when the gas gets ionized after passage of electric current through it and it becomes a conductor of electricity. >In ionized state atoms break into electrons(-) and ions(+) and the system contains a mixture of ions, electrons and highly exited atoms.
Advantage of Plasma Arc welding
>less operator skill requires
>high welding rate
>High penetration capabilities
Disadvantage of Plasma Arc Welding
>It is very expensive equip ment
>High distortion
