Welding Rotator

Standard Welding Rotator

Description of Standard Welding Rotator:
Our standard welding rotator is mainly used for handling and automatic welding circular metal containers, and can be widely applied to oil industry, press vessel field, wind power production line, pipe line production sector, and many other round workpieces.
Our HGZ-type standard welding rotator is designed and produced to better satisfy the growing demands for the pressure vessel manufacturers both domestically and internationally. It can deal with a wide range of diameters, and it adopts frequency conversion setting and stepless speed regulation mode.
So it enjoys more outstanding advantages over similar products. This rotator features stable and reliable performance, low noise, easy operation, and more. It has passed the CE certification, and has been exported to many countries such as Brazil, India, Jordan, South Africa, UK, Poland, Spain, etc.

Designed for automated welding of circular metal containers, this industrial welding rotator excels in oil & gas pipelines, pressure vessel fabrication, wind tower production, and pipe manufacturing applications. The welding positioner features wide diameter compatibility (customizable) with precision frequency conversion control (0.5-15 RPM stepless speed), ensuring ultra-stable rotation (<0.1mm runout) and low-noise operation (<65dB).

Key Benefits:

✓ CE & ISO 9001 certified for welding automation compliance

✓ Global reliability – exported to 20+ countries (UK, EU, Middle East)

✓ User-friendly PLC interface for seamless welding process control

Ideal for heavy fabrication, structural steel welding, and industrial tank manufacturing, this welding rotator enhances arc welding precision while reducing workpiece handling time.

The welding rotator is engineered for precision rotation in industrial welding applications, featuring a heavy-duty roller frame with box-type steel construction for optimal load distribution. Its precision linear guide system ensures ±0.1mm positioning accuracy, while the quick-lock mechanism provides rigid fixation during operation. The high-strength ZG45 cast steel rollers (HRC 55-60 hardness) deliver a 30-ton dynamic load capacity per roller, making it ideal for pressure vessel fabrication, pipeline welding, and structural steel manufacturing.

The dual-motor drive system (2×7.5kW AC motors) offers stepless speed control (0.5-5 RPM) with ±2% torque synchronization, ensuring smooth and stable rotation. Advanced features include:

Hydraulic elevation adjustment (±50mm) with automatic centerline alignment

Anti-creep mechanism (<0.5mm deviation) for consistent weld quality

NOVO displacement sensors (0.01mm resolution) for precision measurement

Siemens/ABB PLC control with IP65 protection for reliable operation

Performance Advantages

✓ 40% higher positioning accuracy than conventional welding rotators

✓ 35% longer service life for critical components

✓ 50% faster adjustment for improved productivity

Applications:

Wind tower fabrication

Shipbuilding components

Energy equipment manufacturing

This welding rotator combines German precision components with robust Chinese manufacturing, delivering unmatched performance for industrial welding automation. CE and ISO certified, it ensures reliability in the most demanding fabrication environments.

Features of Welding Rotator

1. The rollers’ distance automatically adjusts to accommodate different barrel diameters.
2. Speed is adjustable via a frequency control system, enhancing operational reliability.
3. Easy operation is ensured with a manual control box.
4. Available in multiple configurations, including movable and lifting types.
5. A specially designed roller bed offers enhanced convenience during welding.
6. Rollers can be crafted from a variety of materials, such as black rubber, polyurethane, and steel.

Maintenance of Welding Rotator

1. This welding rotator needs cleaning before putting into use. And to avoid aging, the rubber rollers should stay away from oils and high temperature. If possible, there should be a specific person to operate and maintain this device.
2. Before starting, the speed reducer should be full of 30# engine oil, which is also necessary when the environment temperature is below 0ºC.
3. The oil inside the speed reducer should be completely replaced after the use of first month, and later, the engine oil can be changed every six months.
4. The roller bed can not be used as the welding ground so that bearings can be prevented from damaging.
