Brazing and soldering are processes which are much like welding and which often shade over.into welding. The brazing of brass is welding, except that the metal is not pounded together, but melted. The definitions for soldering and welding are given in the first chapter. Brazed and soldered joints resemble welded joints in as far as the solder and the metal of the piece or utensil amalgamate at the joint. But such joints are different from welded joints because the solder or spelter is of different composition from the metals it joins and serves the purpose of a go-between.
