Welding broken non-ferrous castings
DO YOU HAVE BROKEN NON-FERROUS CASTINGS? http://www.pagebiz.com/durafix/
Now you can repair aluminum pot metal and zinc based parts with out a
welding machine.
All you need is a Bernz-o-matic® type torch for small pieces. Produces
a sound joint that is stronger than the parent metal. No fluxes are
needed. No fumes are created. Low 732° working
temperature.
How to weld Zinc based metals such as Pot Metal and Die Cast Zinc with
3 IN 1 rod:
Vee the broken edges to about 45 degrees, clean the surface of any
plating or scale back from edges of the vee 1/8 inch. Heat metal until
it starts to flow. Turn flame paralell to surface and with side of
flame. Hold metal at this heat. Heat welding rod to same temperature.
Now with both base metals and welding rod at this temperature, touch rod
to the surface and the rod will flow into the vee, thoroughly fusing the
parts. Repeat operation until break is completely filled. Be sure to
kick rod into weld to break down skin resistance as filler rod will lay
on surface and will not fuse if only heat is applied.
How to braze Aluminum with 3 in 1 rod:
Brush surface to be repaired thoroughly under heat to break up surface
oxide. Heat the metal hot enough to flow without the aid of the flame
thoroughly tinning the surface. Brush Tinned surface under heat
thoroughly filling the open pores. With sides thoroughly tinned, flow in
enough rod to fill the Vee. Be sure filler metal fuses with the tinned
surface without melting the base metal.
