Sweating Copper

Sweating copper refers to the process of joining copper pipes using solder. This method is commonly used in plumbing and construction to create secure and leak-proof connections. The term "sweating" is derived from the heat involved in the process.

To sweat copper, the two copper pieces to be joined are cleaned and coated with flux, a substance that facilitates the soldering process. The pieces are then heated using a torch until they reach the melting point of solder. Solder, typically a lead-free alloy of tin and copper, is then applied to the joint, where it melts and forms a bond between the two pieces. As the solder cools and solidifies, it creates a strong and durable connection, ensuring the integrity of the plumbing or construction system.

Sweating copper is preferred for its efficiency and reliability in creating sealed joints. The process eliminates the need for complex fittings and provides a cost-effective and relatively simple way to connect copper pipes in various applications, including water supply lines and heating systems. The resulting joints are resistant to leaks and provide a long-lasting solution for plumbing installations.
