Temperature control
The TRUMPF temperature control registers the intensity of the thermal radiation on the component surface and controls the laser power based on the nominal temperature.
Request offerAlways the right temperature
The TRUMPF temperature control registers the intensity of the thermal radiation on the component surface and controls the laser power based on the set nominal temperature. When used in laser plastic welding and laser case hardening, it ensures consistent results – even when working with complex component geometries. When used with a scanner, the temperature controller is integrated directly into the electronics of the PFO. The pyrometer also sits directly on the optics – external units are not necessary. There is a compact control box included in the scope of delivery with the fixed optics.
Temperature control for laser hardening
In the case of laser hardening, the pyrometer measures the surface temperature during the hardening process and regulates the laser power in a spatially resolved manner. This makes it possible to avoid a build-up of heat on the edges, holes, and corners of the components and to achieve a uniform hardness depth at a defined degree of hardness. By
using the scanner optics, you can harden all manner of geometries. And with the oscillating laser beam, you can even produce varying track widths.
Temperature control for laser plastic welding
The TRUMPF temperature control for laser transmission welding of plastics measures the temperature of the joining zone with a pyrometer. The system registers the intensity of the thermal radiation in a pre-determined wavelength spectrum and regulates the laser power to the nominal temperature. Typical applications are the quasi-simultaneous welding of closed contours with scanner optics and the contour welding of round parts with fixed optics.
Quality that is just right
The adjustable nominal temperature and limit value parameters mean that you achieve optimum quality.
Perfectly integrated
Direct coupling of the pyrometer to the optics and parameterization using TruControl.
Full transparency
Guaranteed traceability due to stored temperature data.
The trend at a glance
You can use the trend indicator to detect slow divergence of the process at an early stage.
