Anybody have any tips on welding bronze to bronze.  I need to weld small
pieces of sculpture together--1/8 to 1/4 inch thick pieces.  Have had 
some success with oxy rig and ice.  I would run about an inch bead, then
apply ice to the underside to solidify from the bottom up.  An old timer 
told me about this.  It works but is slow and consumes a lot of ice.  
Also a lot of grinding latter.

Back where I started.

I recently used copper/phosphorus brazing rod to join brass.
Not quite as strong as welding, but much better than solder.
It is normally sold for use on copper pipe.

This type of rod is low melting and if a clean metal is to be
welded/soldered, little or no flux is required. The main reason I don't
like it is the color-mismatch ... the Easy-Flo brand I've used tends
toward grey after it is heated.
I work mainly with silicon bronze and I cast my own 3/16" rods for TIG
welding this Herculoy-type bronze ... it TIG's beautifully. There is also
a fluxed phos-bronze stick welder rod that can be used on most bronzes
(not high Zn brasses) and for welding bronze to cast iron; I used to buy
it from KAR Products and was about $65 / 5 lbs 12 years ago ... haven't
used it for years.
Most of the stuff I stick together nowadays is small pieces and I use a
45% silver solder and a borax-fluoride paste flux.
