Controlled Atmosphere Brazing
Process Overview
Controlled atmosphere brazing is very important for making brazed aluminum heat exchangers in cars. This method uses a furnace filled with nitrogen gas. The nitrogen keeps out most of the oxygen. This stops oxidation during the brazing heat treatment. Workers first clean and get the aluminum parts ready. They put a noncorrosive flux on the surfaces. The flux takes away thin oxide layers. It also helps the filler metal move during brazing.
Next, workers put the heat exchanger parts together. They place them on a conveyor belt. The aluminum brazing furnace automotive system moves these parts through different zones. First, the parts go through thermal degreasing and drying. Then, the furnace heats the parts to the right temperature for brazing. The filler metal melts and flows between the joints. This joins the pieces together. The nitrogen and flux keep the surfaces clean. This helps the metal stick well. After brazing, the parts cool down slowly. This process can handle many parts at once. It is great for making lots of automotive heat exchangers.
The CAB furnace design lets factories make many parts quickly. This makes it cheaper than vacuum brazing for many car uses.
