This kind of brazing machine is linear structure, composed of frame, drive, fire exhaust combustion mechanism, etc.It is suitable for heating copper pipe, copper elbow and brazing ring at fixed point to make brazing ring melt and even fill the gap of copper pipe and copper elbow to realize automatic brazing of two devices.Gas, oxygen, nitrogen, through the large intelligent flow controller FLOTRON/mass flow controller MFC to achieve accurate control of gas flow, to ensure stable brazing temperature and reliable quality.

This type of brazing machine changes the traditional simple assembly-line brazing method. In the brazing process of products, the positions of the fire-exhaust nozzle are divided into preheating and brazing sections corresponding to the different positions of the u-shaped pipe on the heat exchanger, so as to achieve the best welding effect.

The position of fire row can be automatically adjusted up and down in the two stages of "preheating" and "brazing" in the brazing process, so as to ensure better penetration of solder into the brazing seam and more flexible response to u-shaped pipe parts with different diameters, so as to make the flame heating position more accurate and the heat distribution in the heating area more uniform.Compared with the traditional in-line brazing machine, the defect rate of single brazing spot is reduced from 100ppm to 50ppm, and the whole defect rate is reduced from 3000ppm to 1200ppm.
