Four-Way Valve Brazing Machine

The principle of induction brazing:

When the workpiece is being brazed, put the brazing parts of workpiece in the alternating magnetic field, the heating of this parts is produced by resistance heating generated by induction current.

In the conductor, the induction current intensity is proportional to the frequency of the alternating current. With the increase of the alternating current frequency, the induction current increases and the heating speed of the weldment becomes faster. According to this point, we usually use high frequency alternating current for induction heating.

And induction coil is an important device of induction brazing equipment, we can customize induction coil based on different shape.

  • It is suitable for welding of copper joint and pipe fittings, stainless steel joint and pipe fittings, end cap and valve , stainless steel and steel, copper parts and so on.
  • Mainly used in large scale transistor induction heating brazing in sanitary ware industry, automobile industry and instrument industry.
