BHLER WELDING flux-cored wires combine the out-standing welding characteristics of BHLERs rutile stickelectrodes with the productivity advantages of GMAW wires.

BHLER WELDING flux-cored wires provide a powerfulpenetrating arc that deposits a smooth weld with minimumspatter formation.

Additionally, precise alloy adjustments ensure high qualitywelds with excellent corrosion resistance and mechanicalproperties.

To guarantee optimum weld metal chemistry and homogeneityall wires are manufactured utilizing austenitic stainless steelsheaths and agglomerated flux infills.

During manufacturing, an automatic system constantlymonitors production ensuring that the flux fill is uniformlydistributed throughout the entire length of the wire.

All wires are manufactured to DIN EN ISO 9001 qualitysystem.

Cored wires have a wider arc column than solid wires. Therefore they operate with very safe penetration. The risk of lack of side wallfusion is minimized compared to solid wire welding even when the torch is slightly misdirected due to lack of welder concentration.

Optimum parameter settings for 1.2 mm (0.045) wire Range of welding parameters

Dependent on the characteristics of the welding machine optimum parameter setting can vary accordingly. Recommended shieldinggases are Ar and 15 - 25% CO2 or 100% CO2. (When using 100% CO2 it is necessary to increase the welding voltage by 2 V!).The gas flow rate should be 15 - 18 l/min (32 - 38 cubic feet/hr). The wire stick-out should be 15 - 25 mm (19/32 - 1) when welding1.2 - 1.6 mm (0.045 - 1/16) wires and 12 - 20 mm (1/2 - 25/32) when welding 0.9 mm (0.035) wires. Adequate fume extraction isrecommended as always when welding stainless steels. Rebaking: 150C (300F), if necessary!

The trailing torch angle permits good weld pool control whileat the same time promoting defect free sidewall fusion, despitehigh deposition rates.

Torch positioning, positional welding.Slight weaving is recommended for all welding positions

Torch positioning, flat and horizontal welding positions
