Single-pass TIG welding via direct polarity constant current through activating flux layer without preliminary preparation of welding materials.

Advantages:

• possibility produce single-pass, square-groove, full penetration welds up to 10 mm without lining;
• decrease in heat effect on structural transformation in the field of thermal influence;
• possibility welding without packing equipped by additional argon windbox;
• decrease in welding deformations;
• high productivity;
• reduction in labour input;
• saving on electric energy and welding materials.
