TL;DR
Sweating copper is the trade's name for the overall method of assembling copper water lines by torch soldering rather than by press fittings, compression, or push-to-connect couplings. It demands deburred cuts, emery-cleaned mating surfaces, the right flux, and heat control that melts solder without scorching it.
What it means
Sweating copper is the trade's name for the overall method of assembling copper water lines by torch soldering rather than by press fittings, compression, or push-to-connect couplings. It demands deburred cuts, emery-cleaned mating surfaces, the right flux, and heat control that melts solder without scorching it. The skill still defines traditional repipe and repair work, though press tools have displaced it in occupied homes where open flame near framing is a liability.
