Soft soldering - plumbing4home

Soft soldering is a popular way to connect copper pipes and its used for years, constantly developed and improved. This is a reliable way to connect pipes, if used by competent and professional installers. It consists in combining the connector and the tube by brazing at a temperature lower than the melting point of joined elements. The process used is a diffusion phenomenon (the interpenetration of the molecules joined elements and solder). The soldering surfaces should be clean and free of edges and surface of the pipe at the joint should be covered with the flux, which protects the connector and the pipe material from excessive oxidation. If the distance between the elements to be joined is less than 0.5 mm is a capillary brazing when it is greater than 0.5 mm is then soldering slot. Soldering capillary has a higher strength of the connector. Properly made connection capillary soft solder provides a cheap, fast, durable, robust and tight connection.
