I never heard of brazing used on copper. Brazing is done on ferrous metals. Brazing is kind of a way to solder steel in that you are adding a bonding material (brazing rod) to the pieces being joined rather than melting each of joined pieces at the joint at the same moment while adding a fluxed filler material. Flux to keep impurities out of course. Where in MIG welding the gas shroud around the weld point prevents impurities from forming. (Metal Inert Gas = MIG) Tungsten Inert Gas, is the puppy that welds aluminum. (TIG)
Solder is plenty strong for the blocks just getting an even heat across the large surfaces is something I have not done or needed to do before.

Interesting, though as EMC2 said copper/copper can be brazed. Brazing is routinely used in underground copper water piping where a stronger bond than standard solder is necessary  .
