PHILARC CuSi

AWS Specification : AWS A5.6 E CuSi

JIS Specification: DCuSiB

Other Specification: NONE

 

I. APPLICATIONS:

PHILARC CuSi flux coated electrodes are used for welding or building-up silicon bronze as other copper alloys. It is an excellent choice for applications involving cast iron to steel where the part is exposed to corrosives. PHILARC CuSi is commonly used on bronze impellers, bronze wear plates, hydraulic piston overlays, track wheels, gears, sprockets, and quite often farm implements. Should be beveled and preheated up to 500ºF depending on the thickness of the part. Thin sections do not require preheating. Maintain a medium arc length and deposit stringer beads in groove or overlay welding and use weave beads for rapid overlays, large areas and for welding ferrous metals. Peen the weld deposit and remove slag between passes.

     II. DESCRIPTION:

PHILARC CuSi performs well in any position utilizing AC as well as DC machines. PHILARC CuSi weld deposits are strong, ductile and crack resistant-even welding on dirty, oily, burned cast or maliable pars. The high silicon content of this electrode allows it to be used as a welding or brazing electrode.
