Disclosed is a flame brazing control method for copper-aluminum welding, characterized by using a flame generated from the combustion of natural gas, air and oxygen as the heat source, the molar flow ratio of natural gas, air and oxygen is controlled within a range of 1:10-22:0.3-2.2. Further disclosed is an automatic brazing apparatus for copper-aluminum welding, characterized by using a flame generated from the combustion of natural gas, air and oxygen as the heat source, includes three gas delivery systems for natural gas, air and oxygen, a mixer for mixing the three gas, and integrated flow controllers for the electromagnetic valves and flow valves in the three gas delivery systems.
A flame brazing control method for copper-aluminum brazing, characterized by using a flame generated from combustion of natural gas, air, and oxygen as three gases, wherein a molar flow ratio of the natural gas, the air, and the oxygen is controlled within a range of 1:10-22:0.3-2.2 respectively in a flow controller prior to mixing the three gases in a mixer.
