Product Overview

- Our 20 Ton Anti‑Drift Welding Turning Rolls, also known as anti‑creep welding rotator, is specially developed to solve workpiece axial drifting problem during cylindrical component rotation.
- Different from ordinary self‑aligning turning rolls, this anti‑drift system adopts real‑time displacement sensor monitoring to correct workpiece offset automatically, avoiding welding seam deviation and rework.
- With self‑pivoting roller arms, the unit automatically adapts to various cylinder diameters without manual roller spacing adjustment.
Product features
Self‑aligning roller mechanism:
auto adjust roller angle for different workpiece diameters, no manual spacing setting, save setup time.
Heavy‑duty stress‑relieved
welded frame, high rigidity for long‑time heavy‑load workshop operation.
PU coated driving rollers:
high wear‑resistance, protect workpiece surface from scratching.
VFD variable‑frequency
stepless speed control, forward & reverse rotation with stable linear speed.
Wired control pendant as standard
wireless remote controller optional for convenient field operation.
Customizable input voltage:
3‑phase 380V / 415V and other local power standards for global markets.

Frequently Asked Questions
Q1: What is Anti‑Drift function on welding turning rolls?
+
-
A: Anti‑drift system monitors workpiece axial movement in real‑time. It restrains cylinder axial creep during rotation, keeps circumferential welding seam aligned, reduces welding defects and rework.
Q2: Can I add extra idler frames for long vessels?
+
-
A: Yes, we can supply multiple idler frames to support over‑length cylindrical workpieces. Please inform us your workpiece total length.
Q3: Is voltage customizable for our local power grid?
+
-
A: 3‑phase 380V,415V and other voltage options are supported. Please tell us your local voltage and frequency.
Q4: Can this turning rolls work together with welding manipulator?
+
-
A: Reserved signal interface in standard configuration, easy to link with welding column and boom for automatic welding cell.
