A Nickel And Manganese Enhanced Aluminium Bronze Electrode For Welding A Wide Range Of Copper-Based Alloys And Bronze
AL-BRONZE
CLASSIFICATION
AWS A5.6 ECuMnNiAl
PRODUCT DESCRIPTION
A chemically basic flux coated MMA electrode that deposits an aluminium bronze weld metal which as a result of additional Mn and Ni alloying gives superior resistance to corrosion, erosion and cavitation. The flux is extruded onto an alloyed core wire with a blend of silicates that ensures both coating strength and a coating resistant to subsequent moisture absorption
WELDING FEATURES OF THE ELECTRODE
The electrode is designed for use on DC+. The arc is strong and stable resistance to porosity is excellent, provided a back-step strike and re-strike technique is used. The fairly viscous slag is readily controllable permitting positional welding and under most circumstances is readily detached. The weld appearance has a distinctive bronze texture. On heavy sections high pre-heat temperatures are essential.
APPLICATIONS AND MATERIALS TO BE WELDED
Designed for the rectification of initial casting defect and the build up / repair of worn broken castings. The alloy possesses superior corrosion resistance to standard aluminium bronzes and may be used to weld such materials and dissimilar welds between bronzes and steels. The alloy is also suited for welding wrought aluminium bronze products, particularly when resistance to sea water corrosion is a major consideration.
WELDING AMPERAGE AC and DC
OTHER DATA
Electrodes that have become damp should be re-dried at 110oC for 1 hour
