Brazing without secrets

Brazing is a metal joining process that uses a filler metal alloy that has a lower melting point than the metals being joined.

Welding fuses the base metals, while brazing uses a filler alloy without melting the base metals, ensuring a solid joint without deformation.

Brazing is ideal for joining dissimilar metals, requires less heat than welding and generates less distortion.

Silver, phosphorous and brass alloys are the most common, chosen according to the materials and desired resistance.

The temperature varies depending on the alloy used, but is generally between 500°C and 900°C.

Yes, brazing offers high mechanical and thermal resistance, making it suitable for high pressure and temperature systems.

The union may not withstand pressure and thermal variations, leading to leaks or structural failures.

The use of flux depends on the type of alloy and metals. Phosphorous alloys do not require flux in pure copper connections.
