Welding and vacuum brazing are two distinct methods used to join materials, each with its own unique process and temperature requirements.
4 Key Differences Between Welding and Vacuum Brazing
1. Method of Joining Materials
Welding involves melting the base materials to be joined.
Vacuum brazing involves heating the materials to a temperature above the melting point of a filler metal but below the melting point of the base metal, and then using the filler metal to create a bond.
2. Temperature Requirements
Welding requires high temperatures to melt the base materials.
Vacuum brazing uses a lower temperature that only melts the filler metal, not the base materials.
3. Strength of the Joint
Welding results in a joint that is as strong as, or stronger than, the base materials.
Vacuum brazing results in a joint that is strong but may not be as strong as the base materials.
4. Impact on the Base Materials
Welding can potentially alter the materials' properties due to high temperatures.
Vacuum brazing preserves the properties of the base materials as it does not melt them.
