Welding Division - Fluxes

VBC supplies a flux catalyst for use with the GTAW process, which is able to significantly enhance weld bead penetration.

The flux is used with autogenous and added filler metal TIG applications. It is used for stainless engineering alloys and nickel superalloy joints.

The ultra fine powder catalyst is mixed to form a slurry and is painted onto the weld seam outer surface as a thin single pass film and air-dried.

The process is well proven and widely used for critical applications that demand deeply fused welded joints from a single weld pass.

Use of the flux catalyst in a code weld procedure is regarded as an essential variable.

VBC supplies this commodity in 50gm lots. This quantity is able to provide enhanced penetration for over 100M of linear weld bead.

Ask for VBC LDW product, when enquiring for price and delivery details.

Typical applications include production pipe manufacture of high alloy austenitic material for the petrochemical industry, thermocouple probe production in IN718, bellows manufacture, circumferential boss fillet welding, enclosure seal welds.

A mechanism thought to be appropriate for the catalyst concerns reverse Marangoni fluid weld pool flow.
