Braze: Assembly and HeatingLet’s continue the brazing process and quickly review assembly and heating.

Braze: Assembly and Heating

Assembly: The metal components are positioned and secured in place for brazing.

Heating: The assembly is heated using a torch or another heat source. The temperature must be sufficient to melt the filler metal but below the melting point of the base metals.

Brazing Alloy Application: Once the assembly reaches the appropriate temperature, the brazing alloy (filler metal) is applied to the joint. It melts and flows into the joint by capillary action.

To note: When heat is overapplied the metal component (typically copper tubing) will turn a distinct red color (indicating extreme heat) and a hole in the component could result… which is not a good thing.

We’ll continue reviewing the brazing process next time.
