• plasma arc welding (paw)is an advanced version of the tungsten inert gas (tig) welding process.


• the electric arc is formed between an electrode (which is always made of tungsten) and the work-piece.


• the key difference from gtaw is that in paw by positioning the electrode within the body of the torch the plasma arc can be separated from the shielding gas envelope.


• actually all welding arcs are (partially ionized) plasmas but, the one in plasma arc welding is constricted arc plasma.


• the constriction increases the temperature of the arc and also gives it the shape of a fine beam.


• this enables welding at high speed, greater penetration, narrow haz (heat affected zone) and minimum heat input to the job.


• current and gas down slope- programmable current and gas down slope available for automatic closing of key hole during mechanized welding


• igbt inverter based with analog/digital controls & integrated hf arcing systemthat tremendously increases its efficiency and switching characteristic


• sensitivity- less sensitive to changes in arc length


• increased consumable life- recessed electrode reduces the possibility of tungsten inclusions in the weld and can substantially increase the period between electrode dressings resulting in increased life


• more productive- weld in a single pass up to 6 mm plates in square butt position and 10 mm plates in only two passes


• low degree of deformation- keyhole mode of welding gives smaller heat affected zone resulting in reduced strength loss at the joint for heat treated metals, promotes less grain growth which gives better ductility


• less embrittlement- reduced weld time results in less embrittlement by carbides and complex inter-metallic compounds for stainless steel and super alloys


• less residual stress- equalization of distortion stresses results in less residual stress


• reduced porosity- less filler metal required in keyhole mode significantly reduces porosity


• customization of technical features possible

Machine consists of a gantry supported on carriage on operators side & a free roller on the other. Driven by motors one each on X-axis & Y-axis. The motion along longitudinal (Y) axis is powered by digital controlled motor Panasonic or equivalent make coupled with backlash free planetary gearboxes of Panasonic or equivalent make. This arrangement provides smooth acceleration, deceleration & controlled profile cutting speeds. The motion along cross (X) axis is powered by digital controlled motor mounted on the mastercontrol console.

Plasma Cutting Machine consist of Power source with controls, Water Re-circulating system if required and a well designed Torch. The basic principle is that the arc formed between the electrodes and the work piece is constricted by a fine bore, copper nozzle. This increases the temperature and velocity of the plasma emitting from the nozzle. The temperature of the plasma is in excess of 20, 000C and the velocity can approach the speed of sound. When used for cutting, the plasma gas flow is increased so that the deeply penetrating plasma jet cuts through the material and molten material is removed in the efflux plasma.
