You can find copper pipes throughout most buildings. They are used to transport water, high-pressure air, and refrigerants throughout a building. Connecting, joining, and building these piping masterpieces together from one end of a building to the other are typically done by either soldering or brazing. Both are metal-joining processes that melt and flow a filler material into the joint adhering to the metals. The difference between soldering and brazing is the temperature used for melting the filler material, where brazing requires a higher temperature. These two methods can be dangerous and should be performed by a trained professional.
