How well do you know your column & boom welding machines?

This complete guide about column & boom welding manipulators will help you with all the knowledge you need! You’ll know everything about them!

Apart from that, we’ll also give you the best tips on where you should look to get the best machines!

Without further ado, let’s get on to the guide!

What is a Column & Boom Machine?

It’s’ a kind of a welding manipulator that can help you with many types of welding.

Column and Boom Machine

The boom is the welding arm or the welding extension hand. It reaches far places off of the workpiece, helping welders achieve complex welds easily.

The column is a machine where the boom can travel up and down, which is planted on the ground.

You can choose to use them for workpieces that are hard to large, hard to reach, and the like.

Here’s a quick video of what a column & boom welding machine is:

How Does a Column & Boom Welding Machine Function?

It functions as a type of machine that can perform the welding for you.

Column and Boom Function

Even if you use a manual column & boom, welders wouldn’t have to hold the weld head. The machine is fixed on the ground via the column, and the boom is the only part moving.

Welding Boom Design and Structure

The design of the welding boom is closely related to that of a robotic arm.

Welding Boom

It’s a machine that continuously moves the weld head closer to the surface of the workpiece. The common structure of a welding boom would include:

  • Boom Arc Swing
  • Rack
  • Gearbox and Gearbox Base
  • Boom Motor
  • Cable Chain

These are the primary parts of a welding boom; if one is missing, it might not be able to work and operate.

Is a Column & Boom a Welding Positioner?

A column & boom is not a welding positioner because it doesn’t move the workpiece.

Welding Positioner

It’s considered as a welding manipulator because the boom is the one moving.

Its main function is to move the welding material to the workpiece.

Oftentimes, a welding positioner is used with a column & boom welding manipulator.

It holds the workpiece in place and does the job of positioning it.

Mechanical Parts of a Column & Boom Welding Machine

A column & boom can be divided into four (4) parts: column and boom, base, and the carriage. Each of them have their own parts.

  • And many more

What Workpieces Can You Work On Using a Column & Boom?

You can work on a wide variety of workpieces, especially those that are heavy and complex.

Workpieces You Can Work on

You’ll be able to work on pipes and tubes, tanks and vessels, even angular workpieces.

So long as it can impose a challenge to your welder, column & boom welding machines can help!

What Welding Can You Perform With a Column & Boom Machine?

A lot of people don’t know it, but they can perform many different welding processes using column & boom welding machines.

What Welding Can You Perform

SAW or submerged arc welding isn’t the only welding solution, it can also include:

  • Gas Tungsten Arc Welding (GTAW) or TIG Welding
  • Gas Metal Arc Welding (GMAW) or MIG Welding
  • Flux-Cored Arc Welding (FCAW)
  • Plasma Arc Welding (PAW)

Here’s a video of the different types and kinds of welding:

What’s a Welding Manipulator?

It’s a technology that helps in the welding process by moving the welder over the workpiece.

Welding Manipulator

Welding manipulators are just part of the many advancements in the welding sector.

How Does a Welding Manipulator Work?

You can understand to the fullest extent how a welding manipulator works. It’s actually simple.

How Does a Welding Manipulator Work

Its purpose is to move the welding head closer to the workpiece; it will allow you to reach parts and areas that a welder with high skills can.

In simpler terms, it enables and enhances the welder’s lifting capability so that it reaches closer to the workpiece or the part to be welded.

What’s a Column & Boom Welding Manipulator?

It’s a type of a welding manipulator that consists of the welding boom and the column.

Column and Boom Welding Manipulator

The column is what helps you to hold the workpiece in place, so that the welder can work on it. Welding booms are the part that helps you have complete coverage of the area being welded.

It’s a perfect machine you can use to handle any welding positions. It’s mainly used to weld on difficult parts of a particular machine or equipment.

What is a Welding Positioner?

It’s also a welding machine, which can help you automate the shifting of the workpiece.

Welding Positioner

Many people confuse weld positioners and weld manipulators, when they are actually two difference pieces of equipment.

Is Welding Positioner the Same as Welding Manipulator?

No, a welding manipulator is not the same as a welding positioner; in fact, they’re a lot different.

Same as Welding Positioner_

You would want to use a welding positioner if you want the workpiece to be kept in place. You would want to use a welding manipulator if you want to reach positions and angles that are far.

So, the welding positioner moves the workpiece, while the weld manipulator moves the weld head.

They have the same goal – to help you with your welding project.

However, they actually have different and separate functionalities and operations.

Why Should You Use a Welding Manipulator?

Why Should You Use a Welding Manipulator_

Welding manipulators can help you with any welding project. If you have welding projects that are difficult to complete, welding manipulators can aid and assist you.

Even the most skilled and the most talented welder would have limitations; that’s what welding manipulators are for.

Who Needs to Use a Welding Manipulator?

You would need to use a welding manipulator if you have a project that has far reach. Meaning, if there are areas that a regular welder can’t reach, using a welding manipulator can help.

In fact, in many welding projects today, almost all welders prefer using it because of its ease.
