Keyhole welding (over 100A)
By increasing welding current and plasma gas flow, a very powerful plasma beam is created which can achieve full penetration in a material, as in laser or electron beam 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.
The plasma arc is normally operated with a DC, constant current (drooping) characteristic power source. Because its unique operating features are derived from the special torch arrangement and separate plasma and shielding gas flows, a plasma control console can be added on to a conventional TIG power source. Purpose-built plasma systems are also available.
Although the arc is initiated using HF, it is first formed between the electrode and plasma nozzle. This ‘pilot’ arc is held within the body of the torch until required for welding then it is transferred to the workpiece. The pilot arc system ensures reliable arc starting and, as the pilot arc is maintained between welds, it obviates the need for HF re-ignition which may cause electrical interference.
The electrode used for the plasma process is tungsten-2% thoria, and the plasma nozzle is copper. The plasma nozzle bore diameter is critical and too small a bore diameter for the current level and plasma gas flow rate will lead to excessive nozzle erosion or even melting.
Normal gas combinations are argon for the plasma gas, with argon or argon plus 2 to 5% hydrogen for the shielding gas. Helium can be used for plasma gas but because it is hotter this reduces the current rating of the nozzle. Helium’s lower mass can also make the keyhole mode more difficult. Helium argon mixtures are used as a shielding gas for materials such as copper.
