The coils of radiators and air cooled condensers are generally formed by brazing, and the common brazing method is gas welding such as liquefied gas welding and oxy-acetylene welding. With the increasing shortage of energy and the continuous rise in gas cost, the HVAC and refrigeration industry is facing unprecedented challenges of rising production costs. The key to reducing production costs is to reduce gas costs.
The fact is that bottled gas is extracted from fossil fuels,which generally comes from coalbed methane and petroleum gas. The increasing depletion of these fossil fuels has become inevitable. Finding and using alternative energy sources is the only way for company to develop.
As a new fuel, hydrogen has the following advantages:
1.High temperature. Oxyhydrogen flame is as high as 2800 Celsius degrees.
2. High efficiency. Oxyhydrogen flame has concentrated heat energy, low heat loss, and fast welding speed.
3. Easy to use. only pure water in the electrolytic cell can produce hydrogen and oxygen gas When turning on the power switch. After ten second,you can ignite oxyhydrogen flame torch and use for brazing.
4. High safety. Hydrogen and oxygen are produced and stored immediately, and produced as much as needed, so there is no explosion risk of bottled gas.Hydrogen is very light. Even if it leaks, it will not accumulate on the ground. Hydrogen is non-toxic, odorless, and is no risk of poisoning.
5. Environmental friendly.The oxyhydrogen flame is a carbon free flame with no black smoke, and the surface of the workpiece is smooth and pollution-free.
Oxyhydrogen generator is a new kind of gas flame brazing machine. Hydrogen is used as fuel and oxygen is used as a catalyst without additional gas cylinders. It can replace carbon-containing gases such as acetylene, natural gas, and liquefied gas. it is suitable for non-ferrous metal welding and brazing such as electric motor brazing,air conditioning tube brazing,air compressor welding.
Therefore, the oxyhydrogen flame copper welding in the HVAC and refrigeration industry can not only achieve good economic benefits, but also greatly reduce costs and improve power.It has also been widely used in various non-ferrous metal welding, carbon steel cutting, and other flame processing.
