Braze: Mark in ActionLet’s conclude the brazing process and DO NOT forget about safety!

Braze: Cooling and Safety

Cooling: After the brazing alloy has solidified and formed a strong bond between the components, the assembly is allowed to cool.

Safety: Let’s not forget about safety as the flames are hot. When brazing ensure you have a small pale filled with water and a rag just in case it is needed. Upon brazing completion, remember the pipes are hot so do not grab immediately, place water and rag on the line as well. In addition, make sure you keep the torch away from your flesh, clothes, or objects nearby.

Conclusion: HVAC brazing is commonly used for connecting copper tubing and fittings in air conditioning and refrigeration systems. It ensures a reliable and leak-free connection, essential for the efficient operation of HVAC systems.

We’ll continue next time and review characteristics employers are looking for when it comes to becoming an excellent employee and HVAC Technician.

If you have any questions or topics of interest, please let me know. For those considering a career in the HVAC industry, let’s talk as our 6-week intensive workshops can get you there fast.

Braze: Assembly and HeatingLet’s continue the brazing process and quickly review assembly and heating.

Braze: Assembly and Heating

Assembly: The metal components are positioned and secured in place for brazing.

Heating: The assembly is heated using a torch or another heat source. The temperature must be sufficient to melt the filler metal but below the melting point of the base metals.

Brazing Alloy Application: Once the assembly reaches the appropriate temperature, the brazing alloy (filler metal) is applied to the joint. It melts and flows into the joint by capillary action.

To note: When heat is overapplied the metal component (typically copper tubing) will turn a distinct red color (indicating extreme heat) and a hole in the component could result… which is not a good thing.

We’ll continue reviewing the brazing process next time.

Braze: Prep and Flux Application

Braze: Prep and Flux Application

by | Jan 24, 2024 | HVAC Program, HVAC Technical Academy

Braze: Prep and FluxWe recently reviewed what HVAC brazing is and what it does, now it’s time for a brief introduction as to preparation and flux application (we’ll continue the brazing process).

Braze Preparation and Flux Application

The surfaces of the metal components to be joined are cleaned thoroughly to remove any contaminants that could interfere with the brazing process.

A flux, which is a chemical cleaning agent, is applied to the joint area. The flux helps to remove oxides and promote the wetting of the filler metal.

Recognizing the ability braze in the HVAC industry is required for success, HVAC Technical Academy workshops are brazing intensive… you will learn by doing.

Interested in the HVAC industry, consider our workshops to help you with the Universal EPA 608 Certification and hands-on learning.

Braze: The Beginning

Braze: The Beginning

by | Jan 19, 2024 | HVAC Technical Academy

Braze 101HVAC brazing is a process used in the heating, ventilation, and air conditioning (HVAC) industry for joining metal components together using a filler metal that melts at a higher temperature than the materials being joined.

Braze or Weld, Here’s The Scoop

Brazing is often preferred over welding in HVAC applications because it allows for joining dissimilar metals and creates strong, durable connections without melting the base metals.

The photo shows a brazing first attempt… wait until another few weeks and see the huge improvement!

We’ll delve into brazing over the next few entries but if you have any questions or suggestions, send me a note…
