Soldering vs. Brazing: Know the Difference
By Shumaila Saeed || Published on January 4, 2024
Soldering involves joining metals using a filler that melts below 450°C; brazing uses a filler that melts above 450°C.
Key Differences
Soldering is a process of joining two or more metal items by melting and flowing a filler metal, called solder, into the joint. The solder used in soldering melts at a lower temperature (below 450°C). In brazing, the filler metal used has a higher melting point, typically above 450°C, which requires greater heat for the process.

The strength of joints created by soldering is generally lower compared to brazing because of the lower melting point of the solder. Brazing provides stronger joints due to the higher melting temperature of the filler metal, which usually forms a stronger bond with the base metals.

Soldering is commonly used in electronics, plumbing, and assembly of metal components in a variety of industries. The nature of brazing makes it suitable for creating strong, leak-proof joints in manufacturing, automotive, and aerospace applications.

The technique in soldering involves heating the metal surfaces to be joined and applying solder, which flows and cools to form a bond. In brazing, the base metals are not melted; instead, only the filler metal is melted and drawn into the joint by capillary action.

Soldering equipment typically includes a soldering iron or gun and various solders, often containing tin and lead (or lead-free alternatives). Brazing requires higher temperatures, achieved through torches, furnaces, or induction heating, with fillers like silver, aluminum, or copper-based alloys.
