We know that the various methods of Automatic and Semi-Automatic Additional processes of welding. ‘Plasma-arc’ welding is one of them. Plasma-arc welding is a substitute of TIG Arc Process, offering greater welding speed and better weld quality, for welding thin metal section current at 0.1A...
Constriction of the arc is usually accomplished by passing the arc through a water-cooled copper orifice. Its purpose is to control and increase the energy density of the arc stream. Plasma arc processes are employed for the welding, cutting, and surfacing of metals. Only welding will be ...

Plasma welding is very similar to TIG as the arc is formed between a pointed tungsten electrode and the workpiece. However, by positioning the electrode within the body of the torch, the plasma arc can be separated from the shielding gas envelope. Plasma is then forced through a fine-bore ...
The PAW (Plasma arc welding) method is related to GTAW (gas tungsten arc welding). This arc can be formed amongthe metalas well as an electrode. The major difference among the PAW and GTAW is that in PAW, the welder is capable in placing the electrode in the torch’s body; so this...

Plasma transferred arc (PTA) welded coatings are used to improve surface properties of mechanical parts. Advantages are the high reliability of the process and the low dilution of substrate and coating material. Processing of surfaces by PTA welding is restricted at the time to flat horizontal posi...
PURPOSE:To obtain penetration beads of a specified width and face beads of a uniform height by controlling welding conditions in such a way as to make the detected value of the inclination of the plasma arc in accordance with the outputs of photodetectors coincident with the set value thereof....
A simulation tool that is valid within the field of tandem arc welding(unsteady, three dimensional thermal plasma flow) has been developed,based on the open source CFD package OpenFOAM. The validation of the electromagnetic part of the solver has been done separately using a problem with a know...
