Let’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.
