Brazing rods

I was told to braze the soft/porousarea on my ford 600 front wheel rim. New for me. Which rod to use as tsc carries 3 different. Bare bronze, flux coated bronze and copper coated steel. Is the last one for stick weld and not brazing?
 
Copper coated steel is for oxy-flame welding. That's what I would use. I repaired a stem hole on my Oliver by welding a heavy washer in place and drilling out the hole.
 

The bronze rod is for brazing and requires flux. The non-coated rod is used with a separate can of flux - with the rod heated it is dipped into the flux which will stick to the rod. The fluxed end is then used for brazing. The flux coated rod does not require dipping since it is already coated with flux. I find the flux coated rod easier to use.

Brazing rod melts at a lower temperature than steel. I find it easier to use on rusted metal which has thin areas. The brazing rod will flow/fill the thin areas with less chance of burning through as will welding rod.

Brazing works best with the rusted area cleaned of rust. If you have not brazed before I suggest some practice first. It is much like soldering only at a higher temperature.
 
the tractor tire store I use had a guy that told me to braze on the inside of the wheel to fill the pourous areas. He also said to use a 7/16 washer for the valve stem. I guess that brings up a couple questions...

1) put the washer on the inside of the wheel?

2) Brazing will hold the washer or do I braze the porous areas and actually weld the washer in place with MIG or OXY?

thanks, Moday
 
If you have a mig you might be surprised how well you can weld up holes in rims with one. I sandblast the rims first. Anything big use a chunk of brass or copper to back it up to hold the weld in place til it cools.
