What are Welding Positioners?
To work at the correct angle and a consistent surface, welders use welding positioners to hold a workpiece and rotate it.
With its fast rotation speed, it can support significant weight even when bearing a lot of weight.
Welding positioners are designed to ensure that the workpiece is always in the most advantageous welding position.

Welding positioner improves the welding output
By eliminating waste in multiple aspects of their work, positioners improve productivity.
The purpose of welding positioners is to ensure as much arc time as possible.
In order to move cranes, chains, grippers and other types of rigging equipment effectively, welders often have to wait for the appropriate positioning of the workpiece, something that may have to be done more than once for one weldment.
Positioners also make it possible for the welder to manipulate the part more quickly.
Large parts can be positioned by one operator, eliminating the need for multiple people to reposition the part.
As a result, there is a labor savings and employees are freed up for other tasks.

Welding positioner improves welding quality
Welding positioners produce consistently high-quality welds, which is one of the major benefits.
It is difficult to produce quality welds when the part moves during the welding process.
If the material is securely fastened, sufficient penetration of the weld will be possible, as well as the ability to complete all welds without interruption.
In terms of weld quality, welding positioners solve many problems since they rotate the workpiece at a controlled rate and speed for a continuous, penetrating weld.
Advantages of a welding positioner
* Tilt and rotate the work piece to make the welding level and ship-shaped, such as the best position for welding.
* High-quality DC motor, smooth operation of the worktable, stepless adjustment of welding speed, large adjustment range, and high adjustment accuracy.
* It can be fixed on a workbench or a special tool for manual welding, or it can be used with a welding manipulator to realize automatic welding. It can also be used for cutting, grinding, assembling, testing and other processes.
* The clamp and the workbench choose a simple mechanical connection method with high positioning accuracy; it is especially suitable for welding flanges, steel pipes and other joints.
* The hand control box or foot switch is used to control the desktop rotation, which is easy to control the rotation; easy to use and simple to operate.
5 things welders need to know about weld positioners
When selecting, operating, and maintaining a positioner, welders should consider these five suggestions, regardless of the size of the weldment.
- Confirm the center of gravity (COG)
It is important not only to take the weight and size of the weldment into account when selecting a positioning device, but also to consider how far the weldment's center of gravity is from the device. The center of gravity refers to the point at which the weldment balances on all axes equally. The point at which the weldment equalizes the pressure on each axis is the COG. The positioner is torqued more when the distance from the device increases. When welders add material and parts to a positioner, the COG changes, so these changes are important to consider.
Variable-speed motors control the table's rotation. It can be controlled either manually or automatically. Choosing the right positioner motor and control depends on the size and speed required for the desired welding operation.
Motor and control choices will be determined by the positioner manufacturer's specifications. A welder should make sure the capacity is adequate for the weldment by checking both horizontal and vertical load specifications. It is important that the positioning device can withstand as much force as possible.
- Connect the weldment correctly
This point in time is where the weldment would naturally separate from the positioning device, because that is where the weldment is attached. Fixtures for production are intended to be used repeatedly for a particular application. An automatic alignment fixture, such as this one, is permanently mounted to the positioner and is shaped so that it's easy to align parts.
The three-jaw chuck is often used to attach round parts. When the part is extended from the table, it should not pull away from the jaws. During and after the welding process, the part may expand or contract depending on how hot and how cold it is, which can affect the grip the chuck has on the part.
In sizing the positioning device, consider the weight and distance added by fixtures and chucks.
How Does The Welding Positioner Work?
It is easy to understand how a weld positioner works - the device holds on to the particular workpiece by actively clutching and gripping it.
When it moves and rotates, it will get into the position that a welder requires.
You can imagine that it replaced the welder's hand in a more precise, accurate and automated way.
What Is 3 Jaw Welding Chuck?
They're known as a surface, a part of a welding positioner that could properly hold hexagonal and round workpieces.
The three-jaw welding chuck can be fixed on the table and clamp the workpiece firmly, and keep the position still when the workpiece rotates.
What's the Difference Between Manual, Semi-Automatic, and Automatic Welding Positioners?
People don't see the differences between them; what makes them different?
In manual welding positioners, the turntable would need to be moved and rotated. It can either be controlled by a foot pedal or by a lever that you can manipulate by hand.
Welding positioners that work with extra accessories such as a torch or stand are called semi-automatic positioners.
Due to the fact that the positioner moves on its own, while the torch only stagnates, it's semi-automatic.
Automated weld positioners use robotics or automated movements to position welds.
In this positioner, the welding head and the rotator are controlled by machines, so no human intervention is needed.
Why Welding Positioning Is Important?
In welding, positioning is not just for the weld's benefit - it offers a variety of advantages to the welder, as well.
To achieve the quality and quantity of welding needed, overhead welding is used.
By understanding what weld positioning does and how it is beneficial to welders, we can easily summarize how important it is.
The many benefits of weld positioning include the ability to meet required positions without moving and stabilizing the weld.
How Does The Welding Positioner Ensure The Safety Of Welders?
One of the benefits from the advantages above is that your welders are safer.
How can it keep welders safe?
That is because of the characteristics of manual welding positioner:
- No need to use ladders, scaffolding and lifts
- Can improve working condition on the ground
- No need for heavy equipment such as cranes and forklifts to fix the workpiece
- No need for welders to move weldments
How to use manual welding positioner correctly?
People tend to believe that welding positioners can't be operated properly, but that's not true.
You can use it in the best and safest possible way by following these simple steps:
- Put the positioner on a stable and flat surface to ensure your safety.
- Choosing the rotational speed will save you from having to change it between welding.
- Set up your welding equipment and make sure it's connected to a ground current.
- Position the welding positioner horizontally at all times
If you follow these steps, you will never have issues with your manual weld positioner!
Which Materials Can Be Used For Welding Positioner Welding?
Torches aren't necessarily carried by welding positioners.
Using a welding positioner, a large workpiece is rotated to be welded.
Welding positioners are responsible for assisting with the positioning of the workpiece during welding.
You can weld certain materials with weld positioners if they can grasp or clutch them.
Welding positioners are commonly used for welding the following materials:
- Tubes and Fittings
- Tanks and Vessels
- Pipes and Elbows
- Uneven Workpieces
- And Many More!
When it comes to the particular workpieces that you'll be welding, welding positioners are not that picky.
What Is The Welding Turntable?
Simply put, it is a rotary machine that can help you complete welding operations.
The welding turntable is a device that can rotate the workpiece at a uniform speed. It can be controlled (manually) or set to automatic.
Example of what a welding turntable looks like
Welding Positioner vs. Welding Turntable
Welding positioner is a general term for equipment that can be used to assist you in completing your project.
The welding turntable is a kind of welding positioner. Its function is similar to a rotating table, so you don't have to worry about the positioning of the workpiece when welding.
In addition to the standard welding positioner can rotate, the faceplate can also be tilted to change the angle of the workpiece, which is more convenient for welding.
How To Use The Welding Turntable?
Using the welding positioner turntable is very simple. In fact, it can be classified into the following steps:
- Before preparing for welding, load the workpiece on the workbench.
- Then use a chuck and bolts to fix the workpiece on the worktable.
- Use the hand control box or foot control box to start the rotation.
- If you use a manual welding turntable, you must hold the filler metal and/or welding head. Otherwise, you can set them to execute at the speed you want.
- Once it is over, you can unload the workpiece from the workbench; the welding is complete.
You can think of it as a machine that frees your hands from the workpiece.
