 diaBEAM
The new diaBEAM system offers vital technical innovations for industrial applications.
The centerpiece is the sensor which consists of pinhole and of allencompassing annular aperture. This set-up allows auto-adjustment
and auto-calibration of the sensor system. The automatic calibration makes the measuring results operator-independent and opens thus a way to real machine comparability.
Besides these important innovations, spatial and temporal resolution
have been improved and measuring time has been substantially
reduced. Measuring the beam profile and determination of a number
of characteristic beam diameters takes just a few seconds. The caustic
can be recorded within 2.5 minutes e.g. taking 60 partial beam profiles along the beam axis.
The auto adjustment guarantees easy handling of the sensor system. Rough positioning is sufficient for carrying out precise measurements.
Auto calibration allows operator-independent determination of the beam parameters. Thus, it is possible to compare the welding quality of one machine with that of another machine, or to set the same weld quality predictably for several machines of the same type by means of the beam profile.
The pinhole allows to record the power density distribution with a high temporal and spatial resolution. The beam core and of the beam edge is characterized by typical threshold diameters automatically, e.g. D10, D50, D90.
Beam caustic is also determined automatically, utilizing a movable z-axis with a travel range of 160mm.
