Learn guidelines to select the most suitable process for joining copper and copper alloy components in air conditioning and refrigeration system. Discover cost effective installation methods that are also clean and debris free.
Learn brazing, proper procedures for flaring, swaging and leak testing techniques, while ensuring safety and standard compliance.
Brazing depends on the ability of the filler metal to penetrate, by capillary attraction, small gaps between the metal surfaces to be joined. Under suitable conditions, the brazing alloy wets and bonds by surface diffusion alloying to form a strong joint. It is important to ensure that the joint preparation takes full advantage of the capillary penetration of the molten filler alloy.
This course stresses the proper Nitrogen purging through an air conditioning or a refrigeration system that will reduce copper oxidation. This process will reduce compressor failure rates and reduce the moisture inside a system. Ester oil that is in the HFC refrigerant system will breakdown at 50 ppm of moisture in the oil. In a vacuum of 250 microns, the moisture in the ester oil is still above 80 ppm of moisture. This will cause an increase in the acid in a system.
