Plasma Welding Machine	Plasma Welded Samples
Perform High Class Welding With High Tech Plasma Welding Systems.

Descriptions:

• 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.

Check out our Plasma Welding features, specifications & scope of supply

Features:

• 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 system that 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
