Variable Polarity TIG (VP-TIG) Introduction
Variable Polarity TIG (VP-TIG) is an advanced, high-precision and highly controllable TIG welding process, specially designed for high-quality welding of easily oxidized non-ferrous metals such as aluminum and magnesium.
Key Advantages
-
Higher welding quality: Large penetration, narrow heat-affected zone, beautiful weld formation, free from defects such as porosity and inclusions.
-
Strong process flexibility: Fully adjustable polarity parameters, suitable for high-precision welding from thin to medium-thick plates.
-
Longer electrode life: Optimized reverse connection time and current significantly reduce tungsten electrode burning loss and improve continuous operation stability.
-
Wide application range: Perfect for aluminum alloy, magnesium alloy, and also compatible with conventional materials such as stainless steel and carbon steel.
Typical Applications
Aerospace, rail transit, shipbuilding, new energy enclosures, high-end pressure vessels and other fields with strict requirements for weld strength, air tightness and appearance.
