300kg U-Type Servo Welding Positioner Rotator for Robotic Arc Welding

300kg U-Type Servo Welding Positioner Rotator for Robotic Arc Welding

Product Overview & Industry Challenge

• A U-type servo welding positioner turns a fixed welding robot into a productive two-station cell, letting the operator load on one side while the robot welds on the other.

• This U-type servo welding positioner holds weldments up to 100 / 200 / 300kg on a servo-driven table, so heavy fabricated parts can be rotated to the best welding angle instead of being clamped by hand.

• Precise rotary positioning on the welding positioner keeps the joint under the torch, improving arc stability and weld-bead consistency on repetitive production parts.

• Connected as an external axis of the welding robot, the welding positioner runs coordinated motion straight from the robot program, with no separate controller to synchronise.

• With IP65 protection, the welding positioner works beside spatter, grinding dust and cooling mist without fouling its drive or bearings.

• Adjustable rotation speed and a stable table height of 800 mm (customizable) suit both small fixtures and large fabricated frames.

• For robotic arc welding, the welding positioner shortens floor-to-floor time because the robot keeps welding while the part is repositioned.

Key Technical Specifications

Core Engineering Advantages

• 100 / 200 / 300kg rated load: the servo rotator carries heavy fixtures and weldments without slipping, so a single welding positioner covers a wide range of part weights.
• Repeatable positioning: rotational accuracy held to ≤1 r/min keeps the joint under the torch cycle after cycle, cutting rework and touch-up.
• Robot external axis: the welding positioner is driven as an external axis of the welding robot, so rotation and welding stay perfectly synchronised.
• IP65 protection: the sealed structure resists spatter, dust and coolant, extending service life in busy welding bays.
• Rigid machine frame: a stress-relieved steel body and a precision gearbox hold the load steady during rotation, protecting accuracy under heavy parts.
• Straightforward integration: PLC and servo-motor components, 380V / 220V power and an adjustable speed range make commissioning quick.

Target Industrial Applications

• Robotic arc welding: the welding positioner rotates and tilts heavy fabrications so the robot always welds in the flat or horizontal position.
• Two-station welding cells: the operator loads one side while the other is welded, raising arc-on time per shift.
• Large-workpiece fabrication: robotic arc welding parts up to 100 / 200 / 300kg are supported and turned without manual lifting gear.
• Batch production: repeatable indexing on the welding positioner keeps identical parts at identical angles for consistent weld quality.
• Robot integration: pairs with common welding robots as a coordinated external axis of the machine.

Procurement & Engineering FAQ

Q: How is precise positioning maintained after many production cycles?

A: Repeatable positioning of ≤1 r/min and a rigid, stress-relieved frame keep the joint under the torch on the welding positioner, and each unit is checked against ISO 9283 principles at commissioning.

Q: Will the welding positioner cope with spatter and coolant in a welding cell?

A: Yes — IP65 protection shields the drive and seals against spatter, dust and coolant, and covers are available for heavy-spatter zones.

Q: Can the welding positioner integrate with our robot controller?

A: Yes — it runs as an external axis of the robot using PLC and servo-motor components on 380V / 220V, and load, table height and tooling are confirmed during configuration.

For robotic arc welding that demands repeatable angle control, this welding positioner combines a 100 / 200 / 300kg load rating with IP65 protection and robot-integrated motion.
