Soldering vs. Brazing: What's the Difference?

Edited by Huma Saeed || By Sumera Saeed || Updated on October 24, 2023
Soldering involves joining metals using a filler with a melting point below 840°F, while brazing uses a filler that melts above this temperature.

Key Differences

Soldering is a process where two pieces of metal are joined using a molten filler metal that has a melting point below 840°F. On the other hand, brazing joins metals using a filler metal that melts above 840°F.

Both soldering and brazing are popular for creating strong joints between metals, but they differ in their applications and strength. While soldering is often seen in electrical circuits and plumbing because of the lower temperatures involved, brazing is used in applications requiring stronger joints, like in bicycle frames or HVAC systems.

Soldering doesn't typically alter the properties of the metals being joined since it uses lower temperatures. In contrast, brazing, with its higher temperatures, can affect the metal's mechanical and structural properties, leading to stronger bonds.

The equipment and techniques for soldering typically involve a soldering iron or gun and solder, which is a combination of tin and lead, or sometimes other materials for specific applications. Brazing, however, utilizes torches that can reach much higher temperatures and brazing rods made of materials like silver or bronze.
