What is a distinct advantage of brazing over welding?

Brazing offers the distinct advantage of being able to join dissimilar metals, which is a significant benefit in many manufacturing and repair applications. This is because brazing relies on a filler metal that has a lower melting point than that of the workpieces, enabling it to flow into the joint without melting the base metals themselves. This characteristic allows for the joining of a variety of different metal types that may not be compatible under welding processes, which typically require both base metals to be melted and may have limitations in terms of the types of materials that can be effectively fused together.

The ability to join dissimilar metals broadens the scope of applications for brazing, making it ideal for situations where different metals need to be utilized for their distinct properties, such as strength, conductivity, or heat resistance, in a single assembly. This makes brazing a versatile technique in industries ranging from aerospace to plumbing, where combinations of metals are common.
