HVAC systems are constantly prone to breakdowns, and this could be an inconvenience especially during the cold season. This is why most people prefer the brazing technique for their HVAC repairs or installation. There are people who refer to this method as soldering or welding, but although the process is similar, brazing for HVAC involves the use of higher temperatures unlike soldering and doesn’t involve melting down the metal pieces as in welding.
Why is it important to braze an HVAC? Some of the advantages include:
The copper tubing is linked together with a torch emitting high-intensity flame and a brazing alloy of silver and zinc for instance. The part is closely fitted to increase the strength of the connection using filler metals. Brazing allows for metals with different strengths and malleability to be joined to form a strong compound of the end product. The end result is a connection that allows the HVAC system to withstand excessive heat and limit the breakdown rate thereby making it last longer.
Brazing has proved to have more advantage than the other metal joining techniques such as welding. It doesn’t require the melting of the metal bases as in welding and this allows for the production of a clean joint that doesn’t need a secondary finish. The brazed pieces are also uniformly heated producing less thermal distortion.
Since brazing involves fitting the metal tubes closely together, there are minimum chances for leakages in the refrigerator, for instance. Flare connections in the HVAC system have microscopic openings that allow for leakages and no matter how skilled a technician is when installing the flares, they may not be able to cover up the openings unless they implement brazing. This is the only way to seal the microscopic openings. These leakages promote rusting and dirt build up on the tubes that result in the breakdown of the HVAC equipment.
HVAC company owners are encouraged to train their employees on brazing techniques on HVAC machines and the safety procedures that come with it. Safety comes first and it is important to have a formal safety training before they are allowed to carry out their duties. The benefits of having your employees formally trained include:
It is both beneficial and important to gain knowledge on cost-effective installation methods and understand the basic guidelines for brazing. Are you ready to have a set of formally trained employees on safety issues and brazing for HVAC? Get in touch with NTT Inc. today and enroll your employees in their HVAC training seminars.
