3D seam welding machines

For complex geometries with multi-axis seams

Coordinated movement for complex suture patterns

3D seam welding machines from Klumpp Welding are designed for components with spatially curved or rotationally symmetrical geometries — wherever simple robot axes are not sufficient. The workpiece is clamped into a robot axis and actively moved during the welding process while the torch is guided at the same time. In this way, three-dimensional seams can be produced precisely, automatically and repeatably — for example on radiator grilles or other complex-shaped components.

Details on 3D seam welding machines

When to use a 3D seam welding machine?

With a 3D seam welding machine, both individual parts and series parts can be manufactured in larger quantities. This solution is designed for components with non-standardized shapes and geometries.

Your benefits with the 3D seam welding machine

The machines typically operate with two robots: one robot positions the component, while a second robot welds it in place. This allows components to be manufactured without direct manual intervention.

The right fixturing technique for your application

Component fixturing can be implemented in various ways depending on the application – for example, using a work table, hydraulic clamping, or specific fixtures. In some applications, conventional fixturing is not required: the components are positioned by robots, with their location detected via tracking and their position determined accordingly.

FAQs

What add-ons are possible?

As an extension, the system can be designed to allow multiple robots to work simultaneously and components to be additionally pivoted via further driven axes. Positioning and tack welding can take place within a single machine, without employees having to intervene again.

How long can the workpieces be?

There is no limit to the length of the workpieces.

What degree of automation does the machine offer?

These machines offer a very high degree of automation, aiming to operate with minimal human intervention.

Which materials and components can be processed?

In principle, any materials can be processed.

What material thicknesses can be processed?

There is no limit to the thickness of the materials.

Is the weld seam possible on the inside or outside?

Both are possible. In 3D seam applications, it often involves navigating around corners and precisely positioning the seam using camera tracking.
