Laser Processing Head PDT
On the Leading Edge

These are the properties which allow the HIGHYAG PDT to tap into new applications for time- and cost-saving laser brazing and welding. With this self-controlled laser machining head, it is now possible to utilize rational laser technology without technological effort, e.g., for welding trunk lids, for roof and sealing duct brazing or for brazing and welding overlap joints (flange welds and fillet welds).

The problem-free use of the PDT is based on a tactile servo motor assisted seam tracking, which is integrated in the machining optical system. This involves a tactile sensor finger, optionally with or without a wire, via an innovative optic-mechanical rotary motion that is directly coupled with the focus guidance system.

The processing head can traverse the laser focus to the precise welding or brazing  position and then safely and accurately guide it over the workpiece during the process. This compensates for tolerances of the component part and inaccuracies of either the programming or the handling machine. The path can remain unchanged, thus significantly simplifying control.

With the help of a PC-based user interface, a parmeterization of the head (control functions, inputs and outputs) is possible.

The modular optic and mechanical design of the head enables versatile use through the wide range of components offered. For the corresponding modules, this makes it possible to set different scales of figures for welding and brazing and use different types of lasers.
