Thermal joining

Our innovative laser systems for polymer welding open up new production methods in automobile manufacture, in medical and sensory technology, electronics as well as in microsystems technology. The laser systems are also suitable for soldering electronic components.

In the laser welding of overlapping plastic components, it is important to adjust the wavelength precisely for the laser beam to penetrate the upper layer before being absorbed by the layer beyond.

Globo welding

A technique that works along the lines of contour welding. A laser beam is focused at a point on the joining plane via an air bearing, frictionless, freely rotating glass sphere. The glass sphere not only focuses – it also serves as a mechanical clamping tool. While the sphere rolls on the component, it applies continuous pressure at a point on the joining plan.

This ensures that the laser beam is only incident at the point at which the contact pressure is also applied. The glass sphere replaces the mechanical clamping device and expands the scope of laser welding for both continuous and three-dimensional applications.

Characteristics and application:
  • Arbitrary joining geometries in two and three dimensions
  • Welding without a clamping device
  • Optimal synchronization of clamping pressure and energy application
  • Suitable for robotic applications
