[TheForge] Candle cups

[Washington, Aubrey O.]

That is very practical, if not very precise.  I can work with that.

As far as I know, that's right. I have always divided em up between fillers that you can work with a butane torch like you'd use for plumbing and those you need acetylene (or I guess oxy-propane, maybe) for. Don't know if that's right--it's kind of a vague distinction.

  That helps. So the main difference between brazing and soldering is the melting point of the filler metal. Is there some arbitrary number between 600* and 1100*F where we change?

Far as I know, welding is where you melt the base metal, like you say. Brazing is melting a third metal between the to parts to be joined at a high temp, say between 1100F and the melting temp of the pieces to be joined; and soldering is the same process only at low temp, usually around 600F.

Ron,
I always find myself confused by the terminology. I've always called it welding if you melt the base metal and flow the filler into the puddle. So when I use copper wire to fuse copper base metal, I call it welding. (But, I don't know that that is the correct term.)

Where I really get confused is in the difference between soldering and brazing. As I understand it, you do not melt the base metal in either process. I also understand (from reading the literature from suppliers) that brazing does not have to involve a copper or brass alloy (as I once thought). Does soldering always involve a lead or tin alloy? So what is the difference?

Aubrey (confused again)

You can "braze" copper with copper house wiring or phoz-copper. Use flux
coated brazing rod on brass. Both work well but get some experience on scrap
before you try it on your pretty project. Ron C

Walt,
I've done that with both steel and copper and it worked fine. I've never
tried brass, but I don't know why it wouldn't work as long as it is well
annealed while you do the flaring. Of course your brazing wire would need
to have a lower melting point than the brass. I might try soldering since
the joint won't show (I assume).

I'm planning a chandelier and thinking of using brass wire wraps, brass
candle cups and wax catchers to brighten it up. I've looked on-line for
cast cups but I've not found what I would like. I'm now looking at using
brass tubing (7/8"x.040); flaring one end open and brazing the tube directly
to the catchers.

Have any of you done something similar?

I'm looking at Metalliferous as a supplier.

Walt
