How to Flux Brazing Joints

Posted by Lucas-Milhaupt Brazing Experts on Mar 30, 2018
Flux is a chemical compound applied to the joint surfaces before brazing. Flux is essential in the brazing process because it prevents oxides from forming and inhibiting the metallurgical bond in brazing. Oxides are the result of chemical combination between the hot metal and oxygen in the air and ...

Brazing Assembly: How to Braze a Joint

Posted by Lucas-Milhaupt Brazing Experts on Jan 18, 2018
The fifth step of proper brazing procedure is where the action happens: this is how to actually braze a joint. Brazing involves heating the assembly to brazing temperature, and flowing the filler metal through the joint. First, the heating process. As we've seen in brazing, you apply heat broadly ...

How to Maintain Clearance for Brazed Joints

Posted by Lucas-Milhaupt Brazing Experts on Oct 30, 2017
Brazing, as we've seen, uses the principle of capillary action to distribute the molten filler metal between the surfaces of the base metals. Therefore, during the brazing operation, you should take care to maintain a clearance between the base metals to allow capillary action to work most ...

How to Repair a Brazed Joint on Aluminum Heat Exchangers

Posted by Lucas-Milhaupt Brazing Experts on Jun 15, 2017
Braze Joint Repair: Aluminum Heat Exchangers Brazing aluminum heat exchangers is a challenging task. Why? Aluminum melts at a low temperature (~1100-1200°F/593-649°C) and does not change color as it heats, so you have almost no notice before the base material melts away. This means there is a tight ...

Stay Current on Resistance Brazing

Posted by BJ Szyjakowski on Jan 19, 2017
The most common brazing processes include torch, induction, furnace and resistance brazing. Of these methods, resistance brazing is the least common heating method. Why? Compared to the others, it is a fast and relatively inexpensive process, but limitations in assembly geometry have restricted its ...
