Question

Brazing differs from soldering primarily in the following:

• A. Type of base metal used
• B. Temperature of the filler metal
• C. Use of electricity
• D. Type of shielding gas used

Hint:

Remember: Brazing occurs at higher temperatures than soldering, typically above 450°C, which is the main distinguishing factor.

Answer 1

The Correct Option is B

Brazing and soldering are both joining processes that use a filler metal to bond two workpieces, but they differ in the temperature at which they occur. Brazing typically uses a higher temperature compared to soldering.
- Brazing involves heating the filler metal to temperatures above 450°C, whereas soldering is done at lower temperatures, usually below 450°C. This is the primary difference between the two processes.
- The type of base metal and the type of shielding gas used can vary in both brazing and soldering depending on the application, but they are not the main factors that distinguish the two processes.
- Use of electricity is not necessarily a distinguishing factor, as both brazing and soldering can use electricity, depending on the method (e.g., induction heating for brazing).
Therefore, the key difference is the temperature of the filler metal used, making option (2) the correct answer.
