Fit Up Rotator – The Ultimate FAQ Guide

Since welding is a hazardous process, you require high-tech machinery that would lessen the prospect of danger and work smoothly without much hassle.

For this purpose, we have sought out Fit-up Rotators for you and through this guide we allow you to explore its characteristics and features.

Get yourself acquainted with Fit-up Rotators as we seek to clear out all your queries and questions with the help of this FAQ guide.

What is the Purpose of a Fit-up Rotator?

You can use a Fit-up Rotator during welding processes in order to join two or more circular vessels or pipes.

It is supported by hydraulic cylinders which are in turn attached to a hydraulic pumping station and also possess common rotators that turn the pipe during the welding process.

Fit-up Rotators are also in charge of placing and removing the huge cylindrical vessels and are efficient in increasing productivity rate as they are quicker than cranes and also do not require labor for operation.

Fit-up Rotators are necessary for you if you require an errorless outcome and are efficient in producing your desired results.

What are the Different Parts of a Fit-up Rotator?

To ensure a rapid and efficient welding process, some of the Fit-up Rotators come with two sets of fit-up roller beds, which in turn possess four separate hydraulic height adjustment rollers that make it easier to assemble multiple circular pipes or vessels.

This kind of Fit-up Rotator does not require you to invest in extra rail tracks due to the abundance of these roller beds.

However, there is another set of Fit-up rotators that you can purchase, consisting of two idle units. One of the units remains fixated on the ground with the help of steel rollers, while the other unit travels on the rail with the help of PU-coated rollers.

For this kind of Fit-up Rotators, you also need to purchase the rail tracks.

They are connected with a hydraulic station, and the hydraulic cylinders need to be able to operate in left-right as well as up-down rotation. They are also attached to an electric control system and come with a remote controller, either with a cable or wireless.

What Are Some Tips You Can Apply for the Maintenance of a Fit Up Rotator?

Fit-up Rotators are sure to provide you with an excellent and errorless performance if you pay attention to their maintenance.

The first step that you need to perform for the maintenance of Fit-up Rotators is to ensure that the roller frame of the Fit-up Rotator is free of all obstacles and that they have no contact with oil or fire.

In case you are using your Fit-up Rotator for the first time, you need to detach the gear from the shield and rub sodium-based grease evenly all over it. You should also apply a generous amount of oil daily on the rolling bearings. You should change the oil of the reducer after every month, while you should replace the engine every six months.

Lubricating the parts of your Fit-up Rotator daily would enable them to function long-term and increase the Fit-up Rotator’s life span.

Always make sure that there are no loose screws before starting any welding process and the load of the vessel matches the capacity of the Fit-up Rotator.

SENLISWELD also offers you free replacement and maintenance of the wearing parts of your Fit-up Rotator, so feel free to leave your machinery with us.

Are Fit-up Rotators the Same as Welding Positioners?

Fit-up Rotators and Welding Positioners are usually mistaken to be the same, however, that is not the case. Even though you might think that they have some similar features, their purposes set them completely apart.

Both of these heavy types of machinery perform the task of ensuring that the vessels you are welding have been situated properly and they are responsible for rotating them in order to carry out your welding operation. But the manner of rotating is different for both.

A welding positioner is a machine whose job is to grasp and limit the movement of the welding material at a specific target but simultaneously rotating it as per the degree of the angle required.

You can use welding positioners to rotate welding materials of any shape or form, whereas Fit-up Rotators can only be used for circular or cylindrical vessels.

Where the welding positioner limits the movement of the welding material to an extent, Fit-up Rotators allow the welding material to rotate freely so that the entire surface is joined thoroughly.

What are the Factors You Should Look for While Purchasing a Fit-up Rotator?

You need to pay attention to the scale and strength of the vessel that you perform the welding operation on, as that is what matters the most in the selection of a suitable Fit-up Rotator. You can also customize a Fit-up Rotator according to your specific measurements.

The durability of the Fit-up Rotator along with its capability to endure the weight as well as the moderation of the welding process should also be focused on. You should also check if the Fit-up Rotator is able to work under the voltage in your area or not.

Make sure you do not get confused between a Fit-up Rotator and a Welding Positioner due to their similar features.

You also have to ensure that you are purchasing Fit-up Rotators directly from a manufacturing company rather than a trading company and that they have all the suitable certifications that can be extended to you.

What is the Price Range of a Fit-up Rotator?

The price range of a Fit-up rotator will vary according to different suppliers depending on the materials used and its functionality.

Nevertheless, Fit-up rotators are pocket-friendly machinery as they are sustainable and work effectively in the long run.

They might considerably be more expensive as compared to conventional rotators but they offer you more features and hence are worth all the money you spend on them.

The prices of Fit-up rotators will also vary according to their size and weight.

The average price of Fit-up rotators might range from around $3,000 to $30,000.

Are Fit-up Rotators the Future of Welding Automation?

Fit-up Rotators have definitely increased the quality and production output of welding products and continue to set a standard that is tough to catch up to.

They reduce the handling of the welding material and enable you to work according to your own pace by either increasing or decreasing the speed of the welding process.

They allow you to proceed with the welding operation without having to change places and through the rotation of the vessel, they offer a clean and smooth weld.

Fit-up Rotators are also often subjected to upgrades and developments and new models are often launched so that they can assist you in a more advanced manner. Hence, with the constant upgrades, Fit-up Rotators can definitely replace all other kinds of welding automation.

Does SENLISWELD Offer You Warranty for Fit-up Rotators?
