TLDR
In this article, a stream of oxidizing gas, such as argon plus 2% oxygen, is introduced into the plasma arc in the region of the plasma nozzle orifice, which improves the stability of the MIG arc.Abstract:
A plasma-MIG welding method and device in which a stream of oxidizing gas, such as argon plus 2% oxygen, is introduced into the plasma arc in the region of the plasma nozzle orifice. This improves the stability of the MIG arc, and higher welding currents can be used, especially with negative polarity on the electrodes and the plasma and MIG arcs.read more

Patent
Gas coagulation device
TL;DR: A device for enhancing the safety and efficiency of a hand-operated electrosurgical pencil having an electrode with a distal end defining a tip for cutting or coagulating biological tissue, which device comprises a nose piece adapted to be mounted about said electrode and containing conduit means defining converging pathways for streams of gas which impinge obliquely on said electrode at or near the tip thereof as discussed by the authors.
Patent
Apparatus and method for welding
TL;DR: In this paper, a method of extracting fume gas from a welding site is described, which is radially intermediate between the shield gas curtain and the shroud gas curtain, and is suitable for arc welding.
Patent
Plasma torch and a method of producing a plasma
TL;DR: In this article, a pair of annular nozzle elements are coaxially disposed on the opposite sides of the cathode, and a magnetic field is developed across the annular outlet opening to cause the plasma jet to rotate along the an annular peripheral edge of a cathode for its uniform emission.
Patent
Method of and device for plasma MIG welding
TL;DR: In this article, two parallel consumable electrodes axially introduced into a plasma arc initiated by a non-consumable electrode and out through a nozzle are maintained at a positive polarity whereby a substantial increase of the deposition rate is achieved.
Patent
Electric arc spraying of reactive metals
TL;DR: An improved electric arc spray process for the deposition of reactive metals is disclosed which utilizes compressed inert gases for atomization as discussed by the authors, which is useful for the application of cathodic corrosion protective coatings on various substrates.
