What is The Working Principle of a Welding Rotator?

A Welding Rotator is an efficient welding machine used to increase welding efficiency and decrease the manufacturing rate.

In those situations when you have to handle heavy round objects for welding, it plays a crucial role. All performance of the Weld Rotator depends on its wheel roller and engine. You need to load the round object on the machine.

Once the object is all set to rotate, the machine then starts the automated welding process. There is a thing to be noted that the Welding Rotator is normally suitable for round object welding because of its rotating movement.

If you try to weld any object on the Welding Rotator, then it will be hard for you to adjust the angle.

What is the Use of Welding Rotators?

The welding rotator is generally used for the assembly, sharpening, and welding of tubing, tanks, oil tanks, and other containers.

A welding rotator may be used in combination with a column and boom and a SAW device to obtain in and out longitudinal welding. It consists of a self-adjusting rotator.

As a result, this unit has advantages such as compact construction, limited cubage, lovely form, lightweight, and easy operation.

The unit may do all types of auto or manual welding. It’s able to enhance welding accuracy, reduce welding labor, and increase productivity.

What is the Self-Aligning Welding Rotator?

Welding Rotator SENLIS

Self Aligning Welding Rotator

This type of welding rotator can work on several sizes of metal works without adjusting or changing the focus of the wheel.

The self-aligned rotator can be used for rotating cylindrical parts such as fuel drums, pressurized containers, silos, oil tankers, pipelines, etc.

It increases the value of productivity, velocity, and the effectiveness of your work, either using automatic welding or manual welding. They have a very crucial function in steel construction as they help to reduce crane operations and functions.

Self-aligning rotators are made of two units. These two units consist of one drive unit and one idler unit. The quantity of drive and the quantity of the idle units can be modified and altered depending on the terms of the welding operation to be carried out.

What is the Conventional Welding Rotator?

welding rotators SENLISWELD

Conventional Welding Rotator

The size of the Conventional Rotator varies from 2 to 2000 tons with greater loads and larger diameter ranges, for both Polyurethane wheels with excess disk and all steel wheels depending on the performance.

The structure and rotator base are carefully crafted to ensure proper balance to support the weight of the vessel or workpiece.  Both the drive and idler frames are outfitted with heavy-duty designed and machined wheel braces that protect the roller axles and bearings.

Features of Conventional Welding Rotator

  • Rotators may be found in a range of applications such as pressure vessels, heat exchangers, boilers, pipe welding, and so on.
  • More productive and reliable options for expanded power in energy, engine, shipbuilding, other sectors, etc.
  • Rapid development and efficiency enhancements
  • Welder exhaustion may be minimized.
  • There is no need to employ a crane for work management.
What is the Fit-Up Welding Rotator?

SENLIS welding rotator fit-up

Fit-Up Welding Rotator

This type of welding rotator uses a hydraulic pump station. It takes into consideration the welding operation to be done. If the welding operation requires specificity, then the best fit welding rotator is one that can specifically carry out the operation.

What are The Differences Between Self-Aligning Rotator and Conventional Rotator?

The primary difference between a self-aligning rotator and a conventional rotator is the manual and auto-handling factor.

  • Self-Aligning Rotator: A self-aligning weld rotator is the best option to weld a variety of objects without the need of adjusting the angle and rotating wheel. This Welding Rotator adjusts and aligns the object automatically and performs welding performance at a high rate.

The working procedure of the self-aligning weld rotator depends on the two power units.

The first power unit is the idler and the second one is the drive unit. You can adjust the quantity of both units according to the object and welding procedure to be carried out.

  • Conventional Rotator: The Conventional Weld Rotator is a heavy-duty manual handling Welding Rotator. The most out-ranking feature of this Welding Rotator is the weight load capacity. Handling heavy objects is like a cup of tea for the conventional Welding Rotator.

For efficient rotating of objects, the wheel of the Conventional Welding Rotator is Polyurethane.

The same as the Self-Aligning Rotator, the Conventional Rotator also has two working units; Idler and Drive.

Both these working units are fitted with the wheel roller. All these together perform a high-class performance with less welder exhaustion.

What is the Mechanism of Operations in Welding Rotators?

Theoretically, this sounds difficult, but the welding rotator has a basic operating process.

The welding rotator works by rotating the substance to be operated on, which is normally a cylindrical object. The welding process will take place when the rotation is in motion.

This essentially ensures that the welding rotators retain and move cylindrical items. The welding operators execute their duties without needing to adjust their location. They continuously turn the vessels themselves, liberating them of crane and tension.

What is The Structural Parts of the Welding Rotator?

Welding rotators have several structural parts that are quite distinct from others due to the design of the welding rotator. Generally, the structural parts of a welding rotator include;

  • The rotating vessel, usually wheels – is the part that turns or rotates the cylindrical vessels and circular materials to be worked on.
  • The idler – this part that supports the rotation of the device and as such can alter the direction of the output shaft.
  • Motor speed regulator – this is known as the transmission device in some welding rotators. This part controls the velocity of the rotation.
  • Rotating wheel border – this part upholds the wheels. This is also known as a rotating wheel frame.
  • The remote controller – foot pedal control or hand remote control, they are used to modify and adjust the speed when needed.
  • The power motor – the DC motor is mostly used but some welding rotators use an AC motor. This part supplies power to the machine and also aids in speed regulation.
  • The electric box – these are the integral parts and as such are needed for the effective running of the welding rotator. Other features can also be added to the machine at the request and requirement of the customer or company.
How to Maintenance Welding Rotators?

Welding rotators are typically powerful, and as such, maintenance cannot be overlooked.

Here are a couple of ideas for maintenance:

  • When using any unit, such as a welding rotator, search it for loose screws, nuts, and nails. Before you use the machine, tighten the screws.
  • Before starting a new project, make sure there are no weld bits or remains on the unit. This can result in an obstacle in the system.
  • Keep an eye out for odd and unexpected noises and movements from the unit, as well as unpleasant scents. Until you use it, do the required repairs.
  • Ensure that the welding operation’s job load is appropriate for the welding rotator in usage. For hard welding products, do not use a welding rotator with a lower capacity.
  • Choose SENLISWELD for the latest technical repair advice for you.
How To Avoid Accidental Damage During Transportation?

You can effortlessly avoid accidental damages during transportation by using proper safety protocols. The safety protocols you need to apply;

  • Wearing proper leather gloves: Always follow the general rule of thumb, and apply your safety first. Whether you are welding round objects or any irregular shape object; make sure that you are wearing welding leather gloves for your hand protection.
  • Handling tool: There are a lot of Welding Rotator handling tools available in the market, make sure that you are using one while performing the welding process.
  • Eye protection: How can you neglect the importance of eye protection in the welding process? Whether you are a welding expert or a beginner, wearing eye protection is a must. Wear high-quality eye protection so that the rays don’t pass it.
  • Transporter: Once the welding process is done, don’t try to move the object yourself. Use a transporter to move the object effortlessly and conveniently.

So, if you apply the mentioned safety protocols perfectly, then we guarantee, you can perform and transport safely during welding.

Is Welding Rotator Same as Welding Positioner?

Many people get confused with these two terms and also about the fact that they have few similarities. They both rotate spherical and cylindrical welding materials but differently. They increase the efficiency and effectiveness of your welding operation.

Welding PositionerSome objects are complex in shape so you have to wonder how to weld and position them. A Welding Positioner is a welding tool used to rotate, move, and hold two complex shape objects for the deep and precise weld.

The welding rotator is quite similar to a welding rotator but they are not the same. The welding positioner is a device that carries out its welding operation by grasping and limiting the motion of the welding material at a fixed point but rotating it according to the degree of the angle.

Due to this structure of the welding positioner, it can be used for any shape and form of welding material. However, for welding rotators, the case is different. The welding rotator tends to be operational only on spherical or cylindrical welding materials due to the constant rotary movement of the wheels.

Whether you want a Welding Rotator or a Welding Positioner, SENLISWELD has everything for you.

What Steps Are Included in the Welding Procedure?

The welding method consists of a series of operations that include introducing the work material to the welding system (or vice versa), generating linear movement between the work material and the welding machine, monitoring the weld quality, such as rpm, orientation, voltage, and so on, and re-positioning the work material for another weld.

The term “automated welding” refers to the process of automatically monitoring the relative motion of the weld head and the work material.

Advanced machining methods include metal inert gas (MIG), tungsten inert gas (TIG), and submerged arc welding (SAW).

The key advantages of automatic welding are increased efficiency as a result of shorter cycle periods and consistent performance as a result of a lower degree of weld flaws as a result of more direct monitoring of the welding operation.

On the negative hand, welding configuration is limited to flat parallel lines, and setting time is augmented.

Do you need assistance deciding on the best welding rotator for your task? Want to make the welder more relaxed while boosting performance?

Welding rotators are available in a variety of sizes and holding capacities at Senlis Weld. We carry the whole line.
