How to Select the Right Welding Manipulator for Pressure Vessels and Pipe Welding
- Boom vertical expansion: Must be higher than the vessel diameter to ensure full coverage
- Max load capacity: The load at the boom extremity should not exceed the rated range. Typical welding manipulator load capacity can range from 300kg to over 1 ton depending on the model
- Workshop constraints: Ensure your overhead crane height exceeds the column height of the column and boom manipulator
- Automation level: Consider whether you need an automatic welding manipulator with PLC control or a manual welding manipulator for basic positioning tasks
Difference Between Welding Manipulator and Welding Positioner
Welding Manipulator: Moves the welding head (torch) to the workpiece. It positions the welding tool, allowing welders to reach difficult angles and positions.
Welding Positioner: Moves the workpiece itself. It rotates, tilts, or turns the component to bring the weld joint into the ideal position.
Application: For large-scale projects like shipbuilding and pressure vessel fabrication, they are often used together—the manipulator holds the torch while the positioner moves the tank or pipe.
Compatible Welding Processes for Column and Boom Welding Manipulator
A column and boom welding manipulator is highly versatile and compatible with multiple arc welding processes:
- SAW (Submerged Arc Welding): The most common application, ideal for heavy fabrication
- MIG/MAG Welding (GMAW): Suitable for carbon steel and stainless steel
- TIG Welding (GTAW): For precision welding on thinner materials or exotic alloys
- FCAW (Flux-Cored Arc Welding): Used in heavy industries like shipbuilding
- PAW (Plasma Arc Welding): For high-precision applications
