How to use oxyhydrogen for copper pipe/tube brazing
Most copper brazing joins is done at temperature from 1100 to 1500 degrees.That is means the great joint strength is required. Oxyhydrogen temperature is over 2800 degree. Moreover,Oxy-hydrogen flame have the features of concentration, small heat radiation area. Okay Energy designed a tank called additive tank for adding alcohol and petroleum ether. It can reduce flame temperature and flame divergence so that oxyhydrogen generators meet welding requirements of different materials.

How to properly use oxyhydrogen flame for copper pipe/tube brazing? One of our customer,an experienced brazing worker,come to our factory sharing us some tips of copper pipe brazing joints.

Tip 1: It is better to weld with silver brazing rods.And the use of flux to remove and dissolve any oxide will result in a joint of better appearance.

Tip 2: Brazing under nitrogen gas.Nitrogen actually displaces the oxygen inside the line, which prevents oxidation.You can see this oxidation on the outside of the line when you are brazing.

Here video show you about copper to copper brazing joints using HHO gas generator.
