220V 35A IGBT Ultrahigh Frequency Induction Heating Welding Brazing Machine

1. Induction Brazing Machine Brief Introduction :

Induction brazing is a process in which two or more materials are joined together by a filler metal that has a lower melting point than the base materials using induction heating.Brazing is a materials joining process that uses a filler metal (and usually an anti-oxidizing solvent called flux) to join two pieces of close-fitting metal together without melting the base materials. Instead, induced heat melts the filler, which is then drawn into the base materials by capillary action.

high frequency induction heating equipment is particularly suitable for heat treatment and quenching, melting, annealing, the metal through the heat forging, extrusion, welding, brazing.

3. Main characteristics of LSW-16 Induction Brazing Machine :

These series are suitable for many applications, for example,(1)Heat treatment of gear and shaft; (2)metal wire and foil heating; (3)tiny or powder material melting

Induction brazing can join a wide range of metals, even ferrous to non-ferrous. Induction brazing is precise and quick. Only narrowly defined areas are heated, leaving adjacent areas and materials unaffected. Correctly brazed joints are strong, leak-proof and corrosion resistant. They are also very neat, usually requiring no further milling, grinding or finishing. Induction brazing is ideal for integrating into production lines.

Due to the adopting of our third generation inverting control technology, These series machines are characterized not only with high power and high frequency up to 500KHZ output, but also with high reliability .

5.Working theory and structure of induction heating brazing forging machine:
In These series machines, series oscillating circuit is applied, through high frequency transformer, low voltage and high current power is output to go through the induction coil. The main oscillating structure is as follows:Inside These series machines, MOSFET and our third generation inverting control technology has been used, that is the soft and dual control and inverting technology. In this technology, output power and frequency can be controlled and adjusted separately, IGBT and soft switching control technology are used in the high frequency switching circuit to control the output power. In the inverting circuit, the MOSFET and frequency tracing circuit is applied to achieve high speed and accurate soft switching control. The adoption of new technologies not only improves the quality and reliability of the machine,but also solve the technology problem on large power induction heating machine and makes it possible to work 100% duty cycle.
