How Column and Boom Manipulators Automate Your Welding Operation?

Welding automation is the integration of various welding machines that individually and collectively integrate into an organization’s welding operations to increase productivity, accuracy, and speed. These machines perform different welding operations.

As welding rotators are used in aligning, moving, placing, and rotating cylindrical objects, while the welding positioner holds, lifts, and moves objects to enhance welding operations.

While other welding machines improve the overall welding operations, column and boom are no exception. This machine works individually as well as combines with other machinery to improve efficiency and effectiveness.

Column and boom are so versatile that they can combine with any other welding machine. The following example demonstrates how column and boom assist in welding automation services.

One of the most common machines that are sold in the welding segment is the circumferential welding machines for welding round steel objects to each other. The circumferential welding operation is a process where the parts are clamped in a chuck that rotates during the welding process.

This circumferential welding machine can be combined with a boom welding module to for example create a pipe spool welding machine. The circumferential welding machine has the workpiece mounted on the rotating chuck during the welding.

When the spool is rotating the column and boom welding segment of the machine moves up and down on the column and changes position on the boom.

Also, various column and boom welding machines are equipped with operating software and also sell the column and boom welding machines as stand-alone welding machines.

What are the Benefits of Using the Column and Boom?

Overall, a welding manipulator improves work productivity, provides more flexibility, and lessens fatigue for your welders, all while ensuring the consistent quality of your welding operations.

  • Mobility

Manual manipulators are made to move faster with built-in swivel casters, while the mechanized ones can both be manually and computer operated. Switching from one workstation to another won’t be as time-consuming and strenuous as it was before. Even a single welder can transfer the manipulator everywhere in the shop on his own.

  • Safe Working Environment

With its adjustable features and safety straps, you can safely move the weld head closer or more distant to the workpiece, which allows you to weld away from the heat zone. It also comes with safety bumpers to assure the gun, the boom, and the manipulator itself stay secured during the welding process.

  • Flexibility and Versatility

Column and boom are the most flexible piece of machinery that is designed to be integrated with other welding equipment. Welding operators can access uneasy locations and perform complex and difficult welding tasks.

With this machinery, they don’t have to worry about the size and structures of the underlying object. The welding head reaches any critical spot with the help of a remote controller.

  • Improved quality

One of the most integral advantages of welding automation is the accuracy that is immensely improved. Just like other welding machinery, column and boom increase the welding accuracy by a great margin. It helps welders in performing welding operations in difficult spots, where it is extremely difficult to reach the welding object.

Also, many operations are continuous and require to be performed again and again. Accuracy is drastically improved as column and boom can be adjusted to save similarly repeating welding operations.

  • Increased Productivity

As we discussed earlier, various welding operations require a lot of similar and continuous operations. Traditional welding forces you to start these operations all over again, every time. This means that welders have to adjust their equipment every time to achieve similar or improved accuracy with manual equipment.

This procedure is time-consuming and doesn’t help in improving the efficiency of production operations in a business. Column and boom solve this problem as they can save the repeating operations so that they can be continuously performed without the need for adjustment again and again.

This process widely helps in improving the production capacity of any business that involves a ton of welding operations.

  • Better User Experience

Welding can be improved if the welder is not comfortable doing its job with ease. Traditionally welders have to reach awkward spaces to perform difficult welds and have to deal with heavy objects. Handling such objects manually is not only dangerous but is extremely tidy as well.

Welders cannot work effectively for continuous periods. Traditional welding also doesn’t offer much in terms of learning new skills and thus, the learning curve remains straight. Column and boom improve the welder’s effectiveness as well.

It allows the chance to integrate human intelligence with mechanical strength. Thus welders can focus more on the technical aspects of the welding operations while column and boom take care of the heavy lifting and accessibility.

  • Reduced Floor Space

Handling heavy objects with traditional equipment used to be a nightmare for welders but equally disturbing for business owners as well. Such equipment covered a lot of areas in a factory and everything in the factories looked like a mess.

Not only the floor area, but these tools also require a lot of maintenance as well. Also, these were difficult to handle and less safe for workers. All these difficulties that were attached with traditional lifting equipment have been resolved by column and boom.

It is a highly reliable piece of machinery and extremely effective at delivering the welding head at tricky spots. Also, it covers a smaller area than traditional equipment.

  • Reduced Welding Costs

An increment in effectiveness and efficiency of a welding operation always indicates to decrease in the expenses that are attached to traditional operations. There is always a lot of residual that is left after an unsuccessful welding attempt.

Through column and boom, the chances of failure and inaccuracy reduce by a great margin. A reduction in welding costs is inevitable once columns and boom are installed to assist wheelers.

It is a capital investment that is designed to reduce the operating expenses of any involved business.

  • Welding Automation

Welding manipulators work exactly like a skilled extra hand on your shop and allow repetitive, quality operations without needing as much manpower.

The ArcBoss Oscillating Unit, for instance, perfectly mimics the movement of the human hand, providing consistent quality without putting too much physical stress on the operator. The operator can even control the manipulator while welding using a remote control.

  • Strength And Durability

Most welding manipulators can handle heavy weights. Just take the ArcBoss for example. The fully extended boom is tested to handle up to 50 pounds of weight. You won’t have to worry about the weld head loosening unexpectedly, or doing welding operations little by little just because the manipulator can’t handle that much weight or pressure.

Integration Of Column & Boom Welding Machines With Pipe Rotators And Welding Positioners

All welding equipment is designed to operate individually. But their true potential is only unlocked when you use them all together. Only then you can achieve true welding automation.

Column and boom are also designed to become a part of the overall welding automation. While welding rotators and welding positioners are involved in handling the heavyweight equipment, column and boom take care of the welding head and deliver it to tough spots.

Handling the machinery is only half the job, performing the actual weld is the other half. This other half is performed with the help of column and boom manipulators.

Fixed Column and Boom

Fixed Column and Boom

Column and boom manipulators fill a different need than rollers and rotary welding positioners in automated facilities, holding the welding torch instead of the weldment.

They often weld parts that are supported either by rotary positioners or by rollers and primarily have two degrees of freedom, moving vertically and in one direction horizontally, with some also able to rotate about their base.

They can also control the angle of the torch and the distance from the welding surface.

They can vary in size from a few feet tall and wide to several stories tall depending on the application. Generally, when working with a rotary welding positioner, smaller column and boom units are required, while when working with rollers.

It is usually on very large diameter pipes and tanks, calling for a very large column and boom unit.

What are the Prices And Availability Of Column & Boom?

Column and boom are standalone machinery that can be operated with integration with other welding equipment. However, the true potential is only fully optimized when you integrate your welding operations with other welding machinery to achieve full welding automation.

Buying all these machines in a package will be much more viable for your business. Prices of all welding machinery vary because almost all buyers in this industry want a custom application of these products for their unique purposes.

Therefore, if you are looking to buy welding machinery including a column and boom you have to contact a supplier that understands your requirements and delivers the right product for your business.

He’ll also provide you a price quote after you mention your custom specifications.
