Method and computer program product for the regulation of a depth of penetration during the thermal joining of workpieces in a laser module

摘要

A method for the regulation of a depth of penetration (t) during the thermal joining of workpieces (3) in a laser module (6), in which, during the joining of the workpieces (3) in the laser module (6) with a measuring device (2) a first depth of penetration (t1) of the laser beam (1) on at least one measuring point (p) is determined, to a to the measuring device (2), that is connected to computing module (4) and transmitted by the computing module (4) at least one control signal (r) is calculated. Subsequently, the computing module (4) is calculated from the control signal (r), the in a parameter (7) which, with the computing module (4) is connected, stored welding parameters for the workpieces to be joined (3) and the in an edge condition module (8) which, with the computing module (4) is connected, stored boundary conditions for the joining of the workpieces (3) at least one correcting variable (s) in order to achieve a desired value of the depth of penetration (t) and transmits these to the laser module (6), whereupon the at least one correcting variable (s) by means of the laser module (6) is adapted to.
