Скачать или смотреть joint brazing 📌🫶🏻

Brazing is a process used to join two copper pipes using a filler metal that melts above 450°C (around 840°F) but below the melting point of copper. The joint area is cleaned thoroughly, flux is applied, and the pipes are heated with an oxy-acetylene or LPG torch until the filler metal melts and flows into the joint by capillary action. Once cooled, it forms a strong, leak-proof bond suitable for refrigeration, air conditioning, and plumbing systems.

Steps:

1. Clean the pipe ends and fitting with emery cloth or brush.


2. Apply flux evenly to both surfaces.


3. Assemble the joint snugly.


4. Heat the joint uniformly using a brazing torch.


5. Feed the brazing rod into the joint until the filler metal flows all around.


6. Allow it to cool naturally, then clean off any residue.
