Steel Pipe Making Machine Tube Induction Welder Solid State High Frequency Welder

Introduction

It is designed for induction (contact) welding of straight seam steel pipes. The high-power capacitor bank C and the inductance coil L form a current-type parallel booster resonant circuit. This circuit ADAPTS to the high-frequency welded pipe with low load impedance and does not need an output transformer. It not only improves the efficiency but also increases the reliability of the whole machine.

Technical features:
Safety. There is no high frequency and high voltage of 10,000 volts in the equipment, which can effectively avoid the phenomenon of emission, interference, discharge, ignition and so on.
with a strong resistance to network pressure fluctuations.
In the full power range has a high power factor, effectively save energy.
High efficiency and energy saving. The equipment from the input to the output are using high-power soft switch technology, so that the power loss to a minimum, to obtain a very high electrical efficiency, and in the full power range has a very high power factor, effectively save energy, compared with the traditional vacuum tube type of high frequency energy saving effect of 30-40%.
Miniaturization and integration of equipment greatly save space. Equipment without step-down transformer, without thyristor regulating function of power frequency inductance, small integrated structure to bring installation, maintenance, transportation, mode and other convenient.
200-500khz frequency range, realize steel and stainless steel pipe welding.

Power supply cabinet

The DC power unit includes rectification, filtering, and logic control parts.
Independent voltage and current display and control system - independent control of the welder even in the event of a problem with the central console.

Center Console

Equipped with LCD screen, power adjustment, motor speed adjustment module, fully realize the centralized control of welded pipe production line.

Inverter cabinet

The inverter part consists of a single MOSFET inverter unit in parallel, and each unit has a self-diagnostic capability for easy installation and maintenance.

Water heat exchanger

Composition: plate heat exchanger, water tank, water pump and electrical control part

Rectifier isolation transformer

The rectifying transformer is the input rectifying part of the equipment. The power supply voltage is reduced from 415V to 200V, which ensures the stable power supply of the equipment and plays the role of isolation to the power grid.
