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 ...

Once you have properly brazed the assembly, you will need to clean the brazed joint. Cleaning a braze joint is a two step process. The first step is to remove all flux residues. Second, pickle the joint to remove any oxide scale formed during the brazing process. Step 1: Flux Removal Flux removal ...

Here’s what that means for Lucas Milhaupt and our aerospace industry customers. What is the AS9100? We’re proud to be part of a group of ...

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 ...

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 ...

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 ...

Join us as our technical team outlines the main elements used in brazing filler metals, along with the most important features of each element. The more you understand about these elements, the better equipped you are to choose and use the correct products for your brazing operation. These are the ...

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 ...

Having clean base materials is one of the Six Fundamentals of Brazing that ensure quality braze joints: 1. Good fit and proper clearance 2. Clean base materials 3. Proper flux/atmosphere 4. Proper fixturing 5. Proper heating 6. Final cleaning Why Clean Base Materials? Make sure your base materials ...
