Brazing copper tubing: It's simpler than it seemsTorch brazing copper tubing is one of the most common–but widely misunderstood–joining processes. It's possible to make sound joints that are just as strong as the copper tube, easier to braze, and less expensive to produce. But first you have to know basic brazing concepts, including joint design, filler metal behavior, and metallurgy.
