Brazing for HVAC: How Much Do Your Employees Know?

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:

It Increases the Durability of the HVAC machine

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 for HVAC is Better than Other Methods

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.

Decreased Likelihood of Leaking

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.

Safety Comes First When it Comes to Brazing

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:

• You will have fewer reported cases of accidents when they are working in a formal line of duty. Most of your employees will know the right safety techniques to protect themselves and the people around them from danger.
• It is a cost-effective venture. You will spend less money on compensating your workers for their injuries or any third party liabilities that may come up.
• It increases the credibility of your company. Most people would opt for a technician that considers safety procedures when handling their HVAC. You would be a go-to company for most people as they have a sense of security and trust when one of your workers comes in to help fix up their HVAC.
• It promotes a positive safety culture in the company. Safety would be the major focus for all the employees for they would understand the negative impacts of compromising on safety.
• It is the legal duty of every employer to promote the safety of the workers while at their workplace. Having them undergo safety training would be fulfilling your legal obligation.
• Safety training provides a forum for the employees to discover new ways that they could manage safety and learn how to implement the techniques in their daily lives.

Which Group of Workers is the most Suitable for this Training Program?

• Stationery engineers.
• Building managers and superintendents.
• Experienced and apprentice HVAC technicians.
• HVAC maintenance and Repair Technicians.
• Building engineers.
• Plant and facility maintenance technicians.

It is both beneficial and important to gain knowledge on cost-effective installation methods and understand the basic guidelines for brazing.
