Get repeatable quality with our durable welding positioners

Our American-made welding positioning equipment lowers manufacturing costs and improves quality. Productivity enhancements average 30% — achieved through fewer welding start-stops, faster deposition, less scrap and superior ergonomics.

The welding positioners our team engineers can ensure consistent quality between batches and operators. By reducing welder fatigue, they also increase productivity. With our consultative approach and decades of experience, we’ll provide the best welding positioner for your application.

Improve your utilization and efficiency metrics

PrestonEastin offers a full line of standard welding positioners. This includes:

  • 2-axis welding positioners — support up to 24,000 Ibs (10,886 kg) and rotate 360 degrees or tilt up to 135 degrees
  • Turntables — hold up to 200,000 lbs (9,071 kg) at a 12 in CG offset
  • Headstocks / tailstocks — rotate up to 35,000 Ibs (16,000 kg) about a horizontal axis
  • Turning rolls — rotate cylindrical workpieces and multisided poles weighing up to 400,000 lbs and 6 in to 30 ft in diameter

When multiple positioners are used, they can significantly increase repeatable quality and productivity.

While our standard types of welding positioners satisfy most load and speed requirements, we understand there are exceptions. To satisfy these, our team will customize equipment for specific applications to achieve safe, repeatable and dependable positioning.

Welding positioners, manipulators and how to use them

Positioners and manipulators are similar but differ in where the workpiece is placed. A positioner holds the workpiece while a manipulator holds and moves the welding heads.

Using a positioner for welding starts with mounting a workpiece to the face plate. This is typically clamped in position. In some cases, however, it’s worth investing in dedicated fixturing.

The 3-jaw chuck style of workholding is an alternative. A motor and gear drive then rotates the face plate or chuck to put the workpiece in the orientation the welder needs.

Tilt action increases the positioning range available. Tilt of the faceplate is achieved through a worm drive that’s manually operated or motor-driven.

Workpiece positioning

Our 2-axis positioners (or tilt/turn or tilt/rotate positioners) provide versatility for manipulating workpieces on vertical and horizontal axes. They are ideal for pipe applications such as flanges and elbows. Welding turntables, on the other hand, are for applications that require workpiece rotation about a vertical axis.

Turning rolls are for larger or heavier workpieces such as pressure vessels and tanks. Headstocks/tailstocks are for rotating a workpiece around a horizontal axis. A headstock alone may be enough for rotating shorter workpieces horizontally. Longer and heavier pieces will need the addition of a tailstock.

2-axis welding positioners

Our 2-axis welding positioners rotate workpieces at 360 degrees or tilt them up to 135 degrees while providing ergonomic positioning. Our standard models have load capacities as high as 24,000 Ibs (10,886 kg) at 12 in and as low as 100 lbs (45 kg) at 1 in.

Welding floor turntables

Welding floor turntables are a high precision, cost-effective method for rotating a workpiece around a vertical axis at various speeds. Our standard line supports capacities from 500 lbs (226 kg) to 200,000 lbs (9,071 kg) at a 12 in CG offset.

Headstock / tailstock welding positioners

Headstocks / tailstocks are ideal for workpieces that rotate about a horizontal axis and require support from one or two ends. Common customizations include adjusting the weight or size and adding another axis of elevation. Our standard equipment can support workpieces up to 35,000 Ibs (16,000 kg).

Turning rolls

Turning rolls rotate cylindrical workpieces and multisided poles. Our standard line will support pipes and vessels ranging from 10,000 lbs (4,535 kg) to 400,000 lbs (181,436 kg) and workpiece diameters from 6 in to 30 ft.

3-jaw welding chucks

Our 3-jaw welding chucks serve as an interface between the flat plate of a positioner and the workpiece. PrestonEastin has three classes: self-centering chucks that are ideal for 2-axis positioners, headstocks / tailstocks and turntables, spin lock chucks that can be mounted using three bolts as well as grippers with single point jaw adjustment for quick release.

Positioning welding heads

Welding manipulators and side beam carriages position welding heads. They better assure the welding tip maintains a consistent speed. This helps operators achieve a higher quality and more consistent weld. As with all of our equipment, cost-effective customizations are possible.

Warranty

We understand the importance of equipment reliability to profitable operation. That’s why every positioner we make is engineered for low maintenance and durability. To show how we stand squarely behind the devices we make, every standard weld positioner is backed with a three-year warranty. Custom positioners carry a 12-month warranty.
