Patent DE-3926540-A1 (DE)
Inventor: DRENKER ALEXANDER DIPL ING
IPC: B23K26/70
Filed: 1989-08-11
Abstract: The invention concerns a method of irradiating coated workpieces with laser radiation, in which the surface temperature of the irradiated workpiece, in particular the zone being worked (20) is measured. In order to determine the temperature ( THETA 2) of the workpiece in the zone being worked (20), even underneath a coating (12), the power of the laser radiation is modulated with a degree of modulation which is low in comparison with the power of the radiation (PL) and, to determine the temperature ( THETA 2) of the workpiece surface (13) at a point where it is covered by at least one coating layer (12), a temperature ( THETA b) is subtracted from the temperature ( THETA 0) at the surface of the coating layer (12), the value of ( THETA b) being calculated by multiplying together the laser power (PL) absorbed by the workpiece (10) and the thermal resistance (Rth02) of the heat flow through the layer (12) into the workpiece (10), determined from the equivalent heat-flow diagram for the workpiece (10) concerned.
