SIC High Efficiency Switch Welder

 Central Control 

The control of DC motor, SIC High Efficiency Switch Welder and cooler on the welding pipe production line is concentrated in the central control board for the convenience of overall control. The display screen is established to show DC current, DC voltage, armature voltage, armature current, excitation voltage and excitation current indication and welder status.

The shape and placement position of the impedance.

The shape of impedance device is generally designed according to the hole pattern of welded pipe. Unless there is special side or local heating requirements, it is necessary to modify it properly. A few unit magnetic bars are used to form an impedance device as far as possible in an impedance device, which is conducive to reducing the divergence of magnetic lines.

The position of placement, in the direction of pipe section, whether induction welding or contact welding, should be close to the inside of the v-corner hole, and close to the V-shaped area and the position of the welding seam.

Technical Features of Equipment                                  

The SIC High-efficiency switch welder is designed for straight seam induction welding of steel tubes. It mainly uses UJ3C120040K3S (SIC) and DSEI60-06A (fast recovery diode), rectifier diodes, and modular Power component consisting of high-power IGBT and other power devices. The high-power capacitor bank C and the inductance coil L form the current-mode parallel boost resonant circuit. This kind of circuit adapts to the high-frequency welded pipe with low load impedance and does not require the output transformer. This not only improves the efficiency but also increases the reliability of the whole machine.

The SIC high-efficiency switch welder owns the following obvious features of significant energy conservation, good welding quality, small size, easy maintenance, low failure rate, and low maintenance cost, etc.
