Variable Polarity Plasma Arc Welding (VPPAW) workstation for aluminum and aluminum alloys. Combines variable polarity TIG and plasma arc welding for single-side keyhole welding with zero-defect quality up to 16mm single-pass thickness.
Model Variants
We can customise all Specification as client needs
Zero-Defect Aluminum Welding :
Independent adjustment of positive (DCEN) and reverse (DCEP) current amplitudes, frequency, and polarity duration ratios cleans surface oxide film while ensuring deep, defect-free penetration and hydrogen gas escape.
High-Energy Keyhole Plasma Technology :
High energy density, jet velocity, and arc force enable single-pass keyhole pool formation for single-side welding of aluminum alloy plates up to 16mm thick.
Application Areas & Functions :
Mainly used for high-precision, zero-defect welding of aluminum alloys in aerospace, defense, marine, transportation, and chemical pressure vessel industries.
Detailed performance metrics, capacity dimensions, and drive parameters across models.
