Leveraging our deep understanding of heavy workpiece machining, Hengtong Petroleum Machinery offers a comprehensive line of intelligent heavy-duty welding positioners. We not only provide welding positioners but also offer a gravity-defying solution that precisely and smoothly rotates workpieces to any desired angle, achieving "flat welds." This allows every welder to perform in the optimal position and unleash their full welding quality potential.

Product Advantages
1. Superior Load Capacity and Torsional Rigidity
Utilizing a Finite Element Analysis (FEA)-optimized design, the box-type structure and high-precision, heavy-duty slewing bearings ensure smooth, vibration-free operation, even under maximum loads and maximum slewing radius.
2. Precise Servo/Variable Frequency Drive
Utilizing imported brand inverters and motors, the machine achieves stepless speed regulation. The tilting speed is smoothly adjustable, enabling millimeter-level positioning accuracy, meeting the requirements of assembly and precision welding.
3. Versatile Workpiece Clamping Solutions
We offer a variety of interfaces, including standard three-jaw chucks, custom chemical fixtures, and platform workbenches, enabling quick adaptation to your diverse workpiece shapes, including cylinders, frames, flanges, and shafts.
4. Intelligent Linkage and Control
Our welding manipulators, welding power supplies, and control systems are optional for coordinated operation. The positioner synchronizes with the welding torch in real time, enabling welding of complex spatial curves and serving as the cornerstone of intelligent, unmanned workshops.
