How To Clean Brazing Metals

Posted by Lucas-Milhaupt Brazing Experts on Sep 26, 2018
Capillary action will work properly only when the surfaces of the metals are clean. If they are contaminated, IE: coated with oil, grease, rust, scale or just plain dirt, those contaminants have to be removed. If they remain, they will form a barrier between the base metal surfaces and the brazing ...

Proper Assembly For Brazing

Posted by Lucas-Milhaupt Brazing Experts on Aug 15, 2018
Once the parts of the assembly for your brazed joint are cleaned and fluxed, it is time to put the assembly together. If the shape and weight of the parts permit, the simplest way to hold them together is by gravity. Hold each part in position for brazing, steadying the parts in correct alignment ...

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 ...
