The main difference between welding and brazing is in the process. In welding, two base metals are melted and fused together to form a strong and cohesive joint. Brazing also joins two metals together, but with a melted filler material.
In short, this filler material has a lower melting point than the two base metals being fused. Brazing melts the filler material between both base metals to join them together.

Brazing Vs Welding
Deciding to use brazing over welding can depend on many factors. Brazing and welding are suited for differing materials, and involve slightly different equipment and techniques.
Welded joints are typically stronger than those that are brazed. So, why is brazing used over welding in some instances? While not as strong as welds, brazing joints are still considered strong and reliable. Brazing is especially favorable for joining dissimilar metals.
Brazing is commonly used in industries like electronics, aerospace, automotive, construction, and more. Using less heat and energy, brazing is used in manufacturing finer mechanical components like jet turbine blades. Brazing processes are also used in making fine jewelry. Brazing is considered a more versatile way to fuse metals.
Most Commonly Used Base Materials in Brazing
Again, the filler material being used in brazing can depend on the specific application and the metals that are being used. Some of the most commonly used metals and alloys that are used in brazing processes are:
Copper/Copper Alloys
- Silver Alloys
- Aluminum/Aluminum Alloys
- Nickel/Nickel Alloys
- Gold/Gold Alloys
- Steel
It’s important for welders to note that a brazed joint’s overall metallurgical properties are influenced directly by the filler metal that is being used.
