PRODUCT DESCRIPTION
The design emphasis of the chemically basic flux is engineered to ensure the optimum weld metal properties demanded by the specification are fully met. The basic flux containing the appropriate alloying elements but minimal iron powder, is extruded onto a high purity ferritic core wire and bound with a blend of silicates that ensure both coating strength and a coating resistant to subsequent moisture absorption
WELDING FEATURES OF THE ELECTRODE
The chemical nature of the flux together with its controlled coating factor allows the electrode to be used at relatively low amps. This factor together with the fairly fluid but quick freezing slag facilitate vertical up welding including controlled penetration root runs. Overall the arc is very stable, slag detachability is good, fillet welds are slightly convex and metal recovery is some 98% with respect to weight of the core wire
APPLICATIONS AND MATERIALS TO BE WELDED
For welding high tensile strength steels used in shipbuilding, off-shore and pressure vessel construction. Also used on high carbon steels as a buffer layer prior to hardfacing and cast carbon steels with poor weldability - particularly those high in sulphur
WELDING AMPERAGE AC and DC
OTHER DATA
Electrodes that have become damp should be re-dried at 150oC for 1 hour
