The invention relates to a method for introducing a defined weakening line by means of material removal on a cover material (20) which has a visible side (22) and a rear side (21) opposite the visible side (22), in which a pulsed laser beam (31) from a laser (30) is aimed at the rear side (21) of the cover material (20) and is guided along a path (50) and at least one observation unit (11) for monitoring the weakening process is provided underneath the visible side (22) of the cover material (20), wherein a second laser beam (61) from a second laser (60) is coupled into the beam path of the first laser beam (31), wherein the first pulsed laser beam (31) is used to produce the weakening line, and the radiation from the second laser beam (61) that emerges on the visible side (22) is detected by the at least one observation unit (11).
