Project Overview
This cooperation case is with a professional mechanical engineering and metal processing enterprise located in Brescia, Northern Italy. The company focuses on the fabrication of cylindrical tanks, pressure vessel components and structural metal parts. To upgrade their automatic welding production line and improve circular welding efficiency of medium and large cylindrical workpieces, the customer officially purchased one set of 20-ton self-aligning welding rotator from our factory.
As a high-standard European industrial order, this project fully meets EU mechanical safety regulations, complete CE certification, local 415V three-phase voltage configuration and strict surface anti-corrosion standards, which perfectly adapts to local industrial production environment in Italy.
Customer Production Pain Points
Before purchasing our equipment, the customer's workshop faced typical welding problems for heavy cylindrical workpieces:
Manual turning for heavy tanks caused low efficiency and uneven welding seams
Unstable rotating speed led to poor circular welding consistency and high repair rate
Traditional fixed-pitch roller stands could not adapt to multi-diameter cylindrical workpieces
Lack of automated auxiliary equipment restricted workshop capacity expansion
Customized Solution We Provided
According to the customer's workpiece diameter range, load requirements and European local standards, we provided a 20-ton self-aligning welding turning rolls solution:
Automatic self-aligning roller design: The rollers swing automatically to fit different cylinder diameters without manual adjustment, greatly improving production flexibility.
Stable VFD stepless speed regulation: Suitable for MIG/TIG/SAW automatic welding, ensuring uniform and smooth girth welds.
High-strength heavy-duty frame: Overall welded structure with stress relief treatment, stable operation under full 20-ton load without shaking.
EU standard configuration: Customized 415V European voltage, complete CE test report, user manual and safety risk assessment file to support local customs clearance and workshop inspection.
High-quality PU rollers: Effectively protect stainless steel and carbon steel workpiece surfaces without scratches.
