Welding Rotator - The Comprehensive FAQ Guide
With the increasing frequency of use of welding rotators, more large-scale industrial manufacturing industries must use rotators to assist welding production.
Do you have a lot of questions about the welding rotators? We have compiled some common instructions on the use of the welding rotators for you.
What is a Welding Rotator?
Welding rotator is just one of many devices that help you to carry out the welding production process more conveniently.
Example of what a welding rotator looks like
Similar to the positioner, the welding rotator can help you do not need to manually move the workpiece during the welding process.
What they do is basically to drive a cylindrical container or any other type of circular workpiece to rotate at a uniform speed, which can switch the direction of forward rotation and reverse rotation.
Can You Make a DIY Welding Rotator?
Of course you can! Tell us your needs, our design team will design what you think in your mind according to your ideas.
Of course it is based on a feasible operating plan.
A homemade or a DIY welding rotator without any additional parts.
However, many people are confused in distinguishing between welding rotators and positioners. Welding positioners are the machines you use where you clamp various workpieces, welding rotators rotate, twist, and turn workpieces automatically.
What Are the Parts of a Welding Rotator?
The picture clearly shows all the parts of the welding rotator.
The regular welding rotator is comprised of two (2) parts: One Idler, One Drive.
Idler Supporting Unit
Idler bracket, also known as "base". It can carry wheels, and the workpiece can rotate on it.
The components supported by the idler include:
- Drive turning roll
- Driven wheel frame
Motorized Drive Unit
Similar to the structure of the idler support unit, the motorized drive unit is also composed of different parts and components.
The motorized drive device is a part of the welding rotator, which emits power and energy to make the welding rotator work.
Among them, the controller and the motor are the two most important parts of the motorized drive device.
These are the components of the welding rotators. Some welded rotor manufacturers and suppliers may add some other parts to enrich this product. These are the common parts that are necessary for welding rotators.
Welding Rotators VS Welding Positioners
Almost everyone is confused about this: What is the difference between a welding positioner and a welding rotator? Is the function the same?
This is a good question.
Sample image of the appearance of the welding positioner
The welding positioner is a device used to drag the workpiece to be welded to move the welding seam to the ideal position for welding operation.
The welding positioner worktable has a degree of freedom of overall turning. The workpiece can be turned over to the ideal welding position for welding. In addition, the worktable has a degree of freedom of rotation.
This product is mainly composed of rotating machine head, displacement mechanism and controller. The speed of the rotating machine head is adjustable, with an independent speed regulation circuit, and the DIP switch directly presets the length of the weld. The inclination angle of the table can be adjusted as required.
The welding rotator drives the workpiece, parts and components to rotate; the welding positioner is repositioning, can rotate and flip, and fix the workpiece in an ideal position so that the welder can reduce the workload.
In which welding processes can the welding rotator be used?
The welding rotator can be used in the production process of submerged arc welding or SAW, and the welding work goes on smoothly.
The welding rotator can be used to supplement and assist a large number of welding processes, including but not limited to:
- Submerged Arc Welding (SAW)
- Tungsten Inert Gas (TIG) Welding
- Metal Inert Gas (MIG) Welding
- Arc Welding
If you choose to use a welding rotator to complete any of these processes, you can expect faster, more accurate, more precise and higher quality products.
Are there manually adjustable welding rotators?
The rotator without a controller or power box is a manually adjusted welding rotator.
Therefore, the manual adjustment welding rotator is a rotator without computer numerical control or CNC functions.
This basically means that workers must manually adjust the speed, frequency and height of the spinner by inputting it to the control system.
This is the true definition of the manual adjustment of the welding rotator.
You can buy a manually adjustable welding rotator and try it out. But in fact, because it requires less control when you use it, experts will even recommend them even more.
Welding Rotator Applications
The welding rotator can be widely used in many welding jobs and business fields.
It is most commonly used in the production of storage vessels and pressure vessels, with the help of the function of welding rotators.
In addition, the most common application of welding rotator also includes welding other equipment:
1. Oil storage tank
2. Water tank
3. Shipyard and ship parts
4. Pressure vessel
Different Types of Welding rotators
Contrary to the perception of many people, the welding rotators are not limited to a single model of machine.
Fit Up Growing Line - one of the most commonly used welding rotators
In fact, there are many other types of welding rotators on the market today. Some of the most common types include:
Adjustable Rotators
These are welding rotators whose steering rollers can be easily adjusted in width and distance to suit the size of the workpiece, or the circumference and width of the material you will be welding.
Fit Up Welding rotators
Similar to the adjustable rotators, the rotator can adjust the wheel spacing to suit the size of the workpiece. The accuracy and precision of the weld can be guaranteed.
Pipe Pinching Rotators
The pipe pinching rotators, judging from its terminology, is a welding rotator that is clamped on pipes or any type of cylindrical objects to help them perform automatic welding.
These machines are the best and the most ideal for solving the problems of tilting or rotating pipes and other materials of the similar state, size, and dimensions.
Self-Aligning Welding Rotators
The self-aligning rotator can automatically adjust the roller to accept any diameter cylinder within the specified diameter range. This type of machine is usually used to deal with changes in the diameter of the cylinder, from job to job. The roller shell of this type of turning roll is hinged on the based and opens automatically when a larger diameter workpiece is introduced. In this type of turning roll, each roller bracket assembly has two independent roller assemblies, so it can support a wider range of work. The two sets of rollers of the drive unit provide final drive to provide better traction for work
Why does the workpiece move on the welding rotator?
When using a welding rotator, both the rotor and the weldment are circular, the distance between the rotor and the cylinder is the same as the length of the cylinder, and the axis is parallel, which will not cause shaking.
If one of the rollers of the welding rotator is damaged, the workpiece on the rotator may cause shaking.
Of course, if the shape or size of the workpiece is irregular, it will also cause shaking. This is because the axis of the rotor is not parallel to the axis of the workpiece.
What are the effects of using the welding rotator on the processing quality?
During the welding process, the welding rotator will be used to complete related operations. The professional design of the welding rotator and advanced production technology, and an automatic tracking system to achieve the application purpose, make the positioning more accurate. When the welding rotator is processed and produced, the process design can be carried out according to customer requirements, so that the welding rotator can better meet the needs of use.
Any problems encountered during processing and production can be analyzed, controlled and adjusted through appropriate methods. In addition, the welding rotator will be tested on the process parameters to make the parameter setting more reasonable, make the processing operation consistent with the equipment setting, and achieve better operation control effects.
Some other FAQs about the product
1. What are the materials of the wheels?
Rubber, polyurethane or steel wheels.
2. What is the difference between conventional and self-aligning?
The conventional welding rotator requires the customer to manually adjust the distance of the rollers within the effective range of the equipment. It's a bit convenient, flexible, and low price.
The self-aligning welding rotator only needs to place the cylinder on the equipment, and there is no need for manual adjustment within the effective range of the equipment, but the price is higher than conventional.
3. What is included in one set of Welding rotator ?
One set Welding Rotator include 1 drive roller & 1 idler roller, and 1 electrical cabinet with hand remote.
4. How to adjust the base of the conventional welding rotator ?
