TYPICAL APPLICATIONS:
Geear teeth, Shafts, Bearing Seats, Sprockets, Pump Impellers,
Wear Pads, Guides.
OUTSTANDING FEATURES :
Dense deposits with low coefficient of friction and excellent
corrosion resistance.
Highly machinable
Excellent control on multi-pass build-ups.
RECOMMENDATIONS:
For build-up and overlay applications on all ferrous and
non-ferrous alloys exceptwhite metals. Superior weldability and
control. Ideal for building up broken or worngear teeth, worn
bearings, valve seats and pistons. Tough high strength joints.
PROCEDURE :
Clean and degrease joint area. Bevel heavy sections and cracks
600-900 vee.Preheat part and melt off drop of flux from end of rod
onto bgining of joint area.Continue heating until flux liquefies.
Deposit alloy drop by drop, feeding into flame asrequired, making
sure each drop bonds properly. Air cool. Remove flux residues
bywashing with water. Use Valbraze 180 C flux for
supplementary.
