What is the primary difference between soldering and brazing?

The primary difference between soldering and brazing lies in the melting temperatures of the filler metals used in each process. Soldering typically involves lower melting temperatures, generally below 450 degrees Celsius (842 degrees Fahrenheit). This characteristic means that soldering can be performed on a wider variety of materials without risking damage due to excessive heat.

In contrast, brazing operates at higher temperatures, above 450 degrees Celsius, and often involves more robust filler metals that can create stronger joints. The lower melting point in soldering makes it ideal for joining delicate components in electronics or plumbing fixtures where heat-sensitive materials could be present.

Understanding the temperature differences is crucial for selecting the appropriate joining process for specific applications, as using soldering in situations requiring the strength and durability of brazing could result in joint failure.
