Don't attack refers to the brazing welding and melting, melting or melting of the flux is a kind of welding method. When the flux of low melting point, called soldering, such as soldering flux; when the high melting temperature, called brazing, such as brazing; when the flux is not melted, and after heating the dispersion cohesion, called dispersed welding. [industrial water cooler]
Brazing is a kind of very high strength, no leakage between good idea. This approach has high connection strength and is subject to the highest temperature limit.
The manufacturer of industrial chillers in many local convergence involves industrial chiller brazing, so black and white or black and white have a causal relationship with cu.
The use of oxygen acetylene brazing equipment that has the highest strength of weld, and no leakage. Acetylene is a pure itch that enters into acetylene, which can produce very high temperature flames.
The operator should adjust the proportion of oxygen and acetylene from time to time to ensure the accurate use of acetylene. Both oxygen cylinders and acetylene tanks are equipped with pressure regulators and gauges. One instrument indicates the pressure in the tank, and the other indicates the pressure of the torch.
Acetylene is a flammable gas, especially when it burns with oxygen. Therefore, in the process of brazing must always wear safety glass mask. Do not place the torch (lit or lit) toward the flame or spark. Apply the spark plug to the welding torch and do not use matches. Adjust the length of the flame with an acetylene valve, and gradually adjust the oxygen valve to obtain the desired flame. "Neutral flame" is a blue cone with a reddish purple at the tip. This flame is most useful.
According to the following steps accurate operation, easy for brazing.
1, completely go to lose the grease at the junction.
2. The contacts are properly joined and fixed.
3, according to the flux factory supply explanation, add flux.
4, average heating recommend temperature, and make welding gun according to "8" shape move from time to time.
5. Adding copper solder to the soldered parts. Do not heat (melt) copper solder with a torch.
6, cooling junction.
7 wash the contact thoroughly with brush and warm water and remove the residual soldering flux.
