Tank Vessel Welding Rotators for Nuclear , Power Plant 200 Ton

1. Quick Detail

• Anti-drift type welding rotator is broadly used in nuclear, power plant, or other heavy duty industry;
• Hydraulic lift type or roller swinging type are available to prevent axial drift of job;
• The displacement sensor is made by NOVO of Germany;
•  The main control applies the PLC and A/D converter unit of MITSUBISHI FX2N.

2. Introduction

This kind of turning-roll or welding rotator is applicable for narrow gap vessel welding on thick-wall cylinder, or it is necessary to prevent axial drift of work-piece during welding. Its adjustment is adopted with roller up-lift type, which is advanced in structure, complete in function, easy in operation and reliable in performance. So it is ideal equipment for improving welding quality and realizing welding automation.

We also tailor made the welding rotator upon your requirements. Please communicate with us for more details.
