An Introduction to Brazing
Soldering is a joining process wherein metals are bonded to-gether using a non-ferrous filler metal with a melting (liquidus) temperature lower than 450 °C (840 °F). Whenever the filler metal liquidus is greater than 450 °C (840 °F), the joining process is considered to be a brazing process rather than a soldering process.
Work Hardening and Annealing of Copper
Experimental process 1. Prepare lengths of copper wire, 6 to 10 inches long, or tubing, 1 to 1.5 ft in length. 2. Ask selected class members to slowly bend the copper—careful not to cause crimping. 3. Once bent, ask another class member to unbend the copper. 4. Discuss why the copper cannot be fully unbent due to work hardening. 5.
