WELDING ROTATORS

ANTI-DRIFT ROTATORS

Anti-drift rotator systems correct and minimise workpiece drift, whilst maintaining a constant centre line height position. Originally developed for the nuclear industry, Key Plant anti-drift systems are designed to suit a range of applications and processes, such as; narrow gap welding, continuous overlay welding and long periods of vessel pre-heating.

The anti-drift system controls both wheel carriages and continually monitors the vessel position through a sensor on the edge of the workpiece. Our anti-drift system can control the workpiece to +/- 1mm. The sensor detects any movement of the workpiece either towards or away from it, and instructs the rotators to counter the drift, restricting the lateral movement of the weld seam.

Anti drift systems within 1mm plus minus movement

Precision Engineering

Key Plant anti-drift systems control the workpiece to +/- 1mm. Giving you the precision your ‘critical’ project demands.

AUTOMATIC WARNING SYSTEM

In the event the vessel exceeds the maximum drift value, the system generates an audible alarm and the rotators come to a delayed halt.
