Is brazing the most commonly used method for joining copper tube?

Brazing is not the most commonly used method for joining copper tube. Instead, soldering tends to be the preferred technique for many applications involving copper tubing. Soldering is often favored for its lower temperature requirements and ease of use, especially in residential plumbing and HVAC work. It provides a reliable joint that is satisfactory for most plumbing applications where strength requirements are not excessively high.

Brazing, on the other hand, involves higher temperatures and is generally used for applications that require stronger joints, such as in industries dealing with high pressure or where thermal conductivity is paramount. While brazing can be used effectively with copper, it is not as widely employed compared to soldering in typical scenarios.

By understanding the distinction between these methods, one can appreciate the contexts in which each is most effectively applied.
