1 A new dimension Three dimensional processing of geometries with automatic re-focussing

2 Autofocus Increased precision and speed in manual welding The scope of delivery of the Autofocus system comprises a control unit, the Autofocus software and a laptop. Highlights Increased precision and speed together with an increase in productivity by up to 50%. Constant laser parameters on the precision part. Optimal results due to adherence to the process parameters. Automatic online focussing Accurate and rapid operating mode Coaxial distance regulation Measuring accuracy at 15 µm 750 Hz sensor rate Simple operating interface to control the Autofocus Input interface to set the process parameters

3 Always in focus The Autofocus system from OR Laser is a unique focussing system for laser units that regulates the distance to the precision part to be processed online. The uniqueness of the system is based on a measuring method, which is carried out coaxially to the processing laser. This means the distance is measured directly in the focus point of the laser and evaluated in the same axis. Hence you are able to work contact-free and independent of direction, and control the distance precisely even in deeper bores or crevices. Mode of operation A laser beam of a wavelength of 655 mm is coaxially coupled in the processing laser. The radiation diffused back from the precision part is absorbed by the sensor at a scanning rate of 750 Hz and evaluated by means of interferometry. The distance so determined is transmitted in the form of a digital signal and processed in a computer aided manner. A controller controls the drive of the lens positioning at a precision rate of up to 50 µm. Field of application Manual laser and build-up welding: In this process the time-consuming focussing of the laser beam onto the precision part is undertaken independently of Autofocus. Hence, the operator can concentrate on the two dimensional processing. The third dimension is controlled by Autofocus! Funktionsprinzip des Autofocus Automated laser joint welding and powder build-up welding: A fully automatic laser welding process is only conditionally achievable due to the lack of CAD data or components of limited tolerance. The laser beam must be consistently readjusted during the process, which demands an automated focussing unit correction/adjustment. A two dimensional automated processing can be mastered easily without any problems. The third dimension is controlled by Autofocus!

4 Autofocus Unevenness. Irregularities in form. The determination of distance in crevices or irregular surface areas is accomplished easily using the Autofocus system. Even angles of up to 80 are registered by the Autofocus. The dynamic sector of the Z axis of 40 mm overcomes all unevenness during the laser process. The measuring method is based upon an intereferometric evaluation of the diffusion of a 655 nm measuring laser beam. Even angles of up to 80 are registered by the Autofocus.

5 It comprises a sensor and positioning unit, which determines the distance to the precision part accurately and positions the focus lens exactly at the required clearance. The benefit of this system is that you can measure directly in the welding point during the welding, jointing or fusing process with a pulsed laser and readjust the focus lens immediately, if necessary.
