X-CELL LRA laser welding

Automated precision

How can processes such as laser welding be automated and optimally embedded in your production workflow?

Whether the solution requires a stand-alone system, seamless integration into the production line, or island manufacturing – with the X-CELL, you are always on the right track.

We are technological pioneers when it comes to welding using lasers. This is because we achieve the best results and optimum process reliability with the X-CELL for laser robot applications (LRA), even for highly demanding material considerations. For example, the following materials can be machined:

  • Steel
  • Stainless steel
  • Copper
  • Aluminum
  • Plastic
  • Plastic/metal

The X-CELL LRA – robot-based laser welding

The X-CELL LRA from ZELTWANGER is an X-CELL optimized for laser robot applications.

Its modular base structure with laser-resistant housing can be adjusted in terms of size and has been specially designed for laser applications that meet laser protection class 1. This means that lasers up to 4 KW can be integrated as standard – regardless of the manufacturer. With adaptations, even lasers up to 16 KW are possible.

Laser welding – these are the methods we use

Remote welding icon

Remote welding

The laser beam is positioned freely on the part using scanner optics.

Welding with supplementary wire icon

Welding with
filler wire

Filler material is added during the welding process.

Laser build-up welding icon

Laser cladding

3D contours are created by building up wire filler material.

Durable welding processes with process monitoring

Due to the high complexity of laser welding processes, the quality requirements for joints are getting more and more stringent.

ZELTWANGER not only supplies the welding process itself, but also offers comprehensive monitoring together with its partners – before, during, and after welding. This reduces the number of rejects in production and increases the system output.

Integrable quality assurance processes

  • Process light monitoring:
    – Monitoring of process light changes
  • OCT (optical coherence tomography):
    – Welding penetration depth monitoring
    – Welding contour and seam surface monitoring
