Welding device is designed for electroslag welding of curvilineal one-direction joints of steel construction. The device runs on flexible rail track placed on the product. The device is block-modular, consists of unified light replaceable assembly. Feed principle of welding wire is separate (independent).

Operating voltage to every wire is applied from separate direct current power supply.

Functional capabilities of welding device provide operational control of technological process of junction welding in wide range of electroslag welding operating parameters, maintain high reliability and repeatability of temperature-time welding conditions.

Control system is designed on base of components of leading global producers:

  • Programmable controller which provides operation of electrical equipment by algorithm specified by special software;

  • Frequency inverter for control of device travel electromotors, welding wire feed and electrode vibration along gap clearance;

  • Touch-sensitive screen for input and display of colour parameters and emergency messages output.

Two device’s operating modes are provided: setup and automatic modes.

Setup mode is intended for operation checkup of all mechanisms of the device.

Automatic mode is intended for automatic (semiautomatic) control of welding technological process according to the given program.
Device control system provides measurement, regulation and stabilization of welding mode’s parameters.

Control of horizontal position of electrode feed block (parallel to slag bath surface) in process of welding of curvilineal joints is also provided.
