Why Copper Pipe Welding Is Critical in Cooling Systems ❄️

Описание: The video shows a refrigeration system repair in a workshop, focusing on flame brazing of copper pipes on the back of a refrigerator or air conditioner. The technician uses a gas torch to heat the copper tubing connection until it reaches brazing temperature. A filler rod is then applied, melting into the joint and sealing the refrigerant line. Nearby tools such as pliers and a small container—likely holding flux or cooling water—support the process.
Flame brazing copper pipes is a core skill in the refrigeration industry. The principle relies on high heat to melt a silver-based brazing alloy, which flows into the tiny gaps between copper joints. Once cooled, it forms a strong, airtight, and pressure-resistant bond capable of safely containing refrigerant under high operating pressure.
This technique is essential in manufacturing and repairing refrigerators, air conditioners, heat pumps, and other cooling equipment. Its main advantage is exceptional sealing reliability, preventing costly refrigerant leaks and ensuring long-term system performance. Similar brazing or welding methods are also used in household copper plumbing and industrial piping, making this process a key foundation of modern thermal and cooling technology.
