Sweat fitting

Sweat fitting is when two pieces of metal are joined together by melting a special metal called solder between them.

Imagine you have two Legos and you want to stick them together. If you just place them on top of each other, they might fall apart easily. But if you melt some plastic between them so that they fuse together, they become a strong, solid piece.

Sweat fitting works similarly to the Lego example. Plumbers use a blowtorch to heat up the metal pipes they want to join together. This melts the special metal called solder which is placed on the joint. Once the solder cools down, it hardens and creates a strong bond between the two pipes.

It's like putting glue between two things to keep them together, but instead of glue, it's melted metal that's doing the sticking.

Sweat fitting is a very important technique for plumbers and other tradespeople who work with metal pipes. It allows them to create secure and leak-proof joints that can withstand water and other fluids flowing through them.
