Soldering and brazing is a process of mechanically joining metal by 
capillary action.  It is essentially a mechanical joint in much the same 
way as one that is riveted.  The metal has pores and the filler fills 
those pores and locks the pieces together.

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?
