How is a keyhole formed in plasma welding?


How is a keyhole formed in plasma welding?

During welding, a keyhole is formed which progressively cuts through the metal with the molten weld pool flowing behind to form the weld bead under surface tension forces. This process can be used to weld thicker material (up to 10mm of stainless steel) in a single pass.See all results for this questionsp.info How is the tungsten electrode protected in plasma welding?The tungsten electrode, which is secured inside the plasma torch and behind the orifice, is protected from outside impurities that would normally attack its hot surface. With this protection, the electrode is shielded from materials that can constantly attack an “exposed” electrode.See all results for this questionsp.info What kind of plasma is used for precision welding?The arc is stable at low welding current levels producing a 'pencil-like' beam which is suitable for welding very thin section material.
