Product Overview
20 Ton Self‑Aligning Automatic Welding Turning Roll is heavy‑duty auxiliary welding equipment for cylindrical workpieces.
The pivoting roller bracket automatically adjusts roller angle according to workpiece diameter, no manual spacing adjustment required.
It delivers stable and smooth rotation for circumferential seam welding, greatly reducing setup time and improving welding consistency for vessel and pipe fabrication workshops.

Frequently Asked Questions
Q1: What does self‑aligning mean for this automatic welding turning roll?
+
-
A1: The roller support arm swings automatically when placing cylinder workpiece, no manual bolt adjustment for different diameter. It shortens workpiece replacement time.
Q2: Can this 20 ton turning roll work with automatic welding machine?
+
-
A2: Yes. Stepless adjustable rotation speed matches SAW, MIG, TIG automatic welding system. We can add welding earth terminal for high‑current welding.
Q3: Is anti‑drift function optional?
+
-
A3: Yes. Anti‑drift device is optional for preventing workpiece axial drifting during long‑hour welding.ess steel is not similar to mineral materials,after use can release some substances to promote human absorption.
Q4: Do you accept custom modification?
+
-
A4: Yes. Travelling base rail, special voltage, steel roller and other customized requirements are acceptable.
Q5: What is your delivery lead‑time?
+
-
A5: Standard 20 ton self‑aligning automatic welding turning roll lead‑time is 15‑20 working days.
