In short, Brazing is a process of melting filler alloy and flowing the molten filler rod into the joint of metals to be welded. As the filler material liquefies and solidifies, a seamless amalgamation emerges.4 Ways to Braze Pipes. 1. Torch Brazing. In torch brazing, the plumber uses a handheld acetylene torch to heat the base material (typically copper or brass). Once the joint is hot enough, they’ll introduce the brazing rod to …When brazing copper, the metal should be a dull cherry red indicating the correct temperature has been reached. As we noted, free-flowing filler metal alloys will flow into and around the joint by capillary attraction. Therefore, you should apply filler metal along the entire joint, building up a fillet.CuPSnNi alloys with a melting range from 590 to 620 °C for brazing copper-brass coolers in the so-called “CuproBraze® process” [15].
