Clamping Tools

Chucks are used to clamp a workpiece or another object on a welding positioner and process it more easily. In particular, cylindrical workpieces or special components. You can clamp your workpiece optimally with the various clamping devices from DUMETA®. Our high-quality clamping means are available in different designs, tolerance ranges and with different adapters. The clamping devices are m ...

Column & Boom Manipulators

Buy a column and boom manipulator to further automate your production. Various controls and welding equipment can be attached and both a gear and chain drive are available to meet your needs. We supply various new and used column and booms with a stroke of 1.5-10 m. The ergonomic design of the DUMETA® welding column and booms ensure user safety, excellent welding results and maximum productiv ...

Used Machines

Buying or renting a used welding positioner or used machine avoids larger investments. As an alternative to new equipment, we also offer high-quality used machines that you can buy or rent. Our used machines and used welding positioners are fully tested, durable and ready for immediate use. They meet the highest customer-specific requirements at a fair price. We offer you a large selection o ...


Most of our machines are supplied with a double foot pedal (start-stop / left-right) and a remote control (by cable). Optionally we also offer a foot pedal for adjustable speed, a radio remote control or a programmable control for welding positioners. Do you have questions regarding the DUMETA® controls, welding manipulators or automation machines? Are you interested in our controls and ...

Welding Rotators

Buy a welding rotator to process and weld your heavy and round workpieces. Welding rotators can easily be adjusted to different diameters of pipes, containers and other workpieces. We supply various welding rotators with a capacity range of 1,000 kg to 1,200 t. DUMETA® welding rotators were developed and manufactured according to the operating requirements of different production sites. ...

Welding and assembly is your speciality? Then you've come to the right place. 


We know the challenges of handling large, bulky workpieces in the production process and how much time it can take to get a component into the perfect welding position.

It is essential for a welder that all sides of a workpiece are easily accessible and visible and that he can weld flexibly in a relaxed working posture. This is the only way he can draw an optimal and clean weld seam, improve the welding sequence and significantly reduce welding distortion.

In most cases, workpieces have to be repositioned several times with the hall crane. Precious working time is lost and the risk of accidents increases. However, manufacturing efficiently can be much easier.

With a welding positioner or a welding rotator, as well as other practical machines from DUMETA, you can use this time for your actual task and at the same time protect your or the health of your employees. Automating workpiece handling will give you a clear advantage. 

For example, your workpiece can be safely tilted and rotated and brought to the correct working height, after it has been clamped on a manipulator. Or it can be rotated on a welding rotator and welded by a column & boom manipulator. You can decide which production steps are to be carried out automatically. DUMETA has developed a control system that is compatible with all brands and can automatically control both rotating and tilting movements.
