Plasma Arc Welding

Plasma Arc Welding is the welding outgrowth utilizing utility generated by a narrowed arc struck between a tungsten non-consumable electrode and either the product example (transferred arc operation) or water cooled constrictive nose (non-transferred arc operation).

Plasma is a airlike assemblage of affirmative ions, electrons and neutralised gas molecules.

Transferred arc touch produces plasma jet of piercing vitality compactness and may be victimized for screechy ratio welding and extract of Ceramics, steels, Aluminum alloys, Metal alloys, Titanium alloys, Nickel alloys.

Non-transferred arc appendage produces plasma of relatively low push density. It is misused for welding of various metals and for ecf spraying (color). Since the convert doctor in non-transferred plasma arc welding is not a piece of automobile raceway, the ecf arc burner may displace from one employ leather to opposite without quenching the arc.
