What is a Welding Positioner?

A welding positioner is a mechanical device used to secure and rotate a workpiece, allowing the welder to work at the most suitable angle and maintain a consistent surface. These devices can spin quickly even under significant weight, ensuring the workpiece is always in the optimal welding position.

Positioners Increase Welding Throughput

Positioners enhance efficiency by maximizing arc time and reducing downtime. Cranes, chains, and other rigging equipment require substantial effort to move, often leaving welders waiting. With a positioner, the welder can quickly manipulate parts, allowing a single operator to handle larger parts and freeing others for different tasks, thus saving labor and increasing productivity.

Positioners Improve Welding Quality

Using the correct welding positioner ensures high-quality, consistent welds. Fixed materials allow for sufficient weld penetration and make uninterrupted repositioning easier. Positioners rotate the workpiece at controlled rates, maintaining continuous, penetrating welds and solving many common welding issues.

Retrain and Attract Skilled Welders

The use of welding positioners offers numerous benefits, including improved safety, the ability for skilled and entry-level welders to perform high-quality rotary welding, enhanced employee morale, and reduced worker fatigue through semi-automatic functions, leading to increased production speed.

5 Things Welders Need to Know About Weld Positioners

Positioning equipment assists in maneuvering large assemblies but is also beneficial for smaller ones. Mechanically positioned weldments, regardless of size, reduce welder fatigue, increase safety, improve weld quality, and save floor space. Proper positioning keeps the work area accessible and safe, preventing uncontrolled motion.

Safety is improved when weldments are anchored properly, avoiding the dangers of cranes and chains. Positioners enable efficient and ergonomic welding by allowing the use of a stationary torch with consistent speed and positioning, resulting in higher quality and repeatability.

For circumferential welds, integrating a positioner with a power source and torch stand can offer semiautomatic welding advantages, such as consistent speed, precise torch positioning, and reduced operator intervention.

Remember the COG

Choosing the right positioner requires considering the weight, size, and center of gravity (COG) of the weldment. Specifications for motor and control must match the required size and speed. The positioner should handle the maximum load, including horizontal and vertical loading capacity.

Attach Weldment Correctly

Secure attachment methods are critical to prevent separation during welding. Fixtures designed for specific applications are mounted permanently, easing alignment. The distance and weight of attachments like chucks and fixtures must be factored into the positioning device's capacity calculations.

Use Turning Rolls for Cylinders

Cylindrical weldments can benefit from turning rolls, which provide steady rotation for even circumferential welds. Rolls support longer pipes and vessels, distributing weight evenly and maintaining the center of gravity.

Keep It Flat

Ensure the positioning equipment is mounted on a flat, stable surface to prevent tipping. Use provided mounting holes to secure the device to a stable surface.

Connect Ground Current to the Positioner

Proper grounding prevents electrical damage and poor welds. Ensure the positioner is compatible with the welding current and secure all ground cables tightly.

Welding positioners have become essential in the construction machinery industry, widely adopted for circumferential seam welding. They can be integrated with various welding machines to form automated systems. The main components include a rotating head, displacement mechanism, and controller.
