The system has been designed for automatic tracking the V-groove joints without filling or with partial filling after welding pass during arc or submerged arc welding. The system consists of two basic part: laser sensor (LS) with microprocessor control and communication module (CM).

The laser sensor provides contactless measuring of lateral and vertical butt-joint center shifting and data transfer to communication module through RS-422 interface. Laser sensor is also equipped with TV-out for visual tracking of the system operation. The main functions of communication module are: laser sensor data receive, forming the signals of lateral and vertical welding head position correction, tracking system tuning, coordination with welding mill main controller, operator pendant and external computer for service parametrization and tracking system setting.

Tracking system is integrated into existing welding mill equipment. The sensor TV-out is connected to the existing remote viewing display. The communication module is facilitated with required interface, digital and/or analogue inputs and outputs for interaction with welding mill and operator pendant (the list of required signals is additionally coordinated with the Customer depending on welding mill type).

The tracking system is based on modern industrial-purpose electronic components and print-boards assuring advanced reliability of the supplied equipment.
