Abstract

The invention relates to a method for laser beam plastic welding, having the following steps: arranging a first mold part which substantially absorbs laser radiation on a receiving area, irradiating the first mold part using an electromagnetic radiation source, detecting the heat of the first mold part by means of a detector, generating an absorption profile of the first mold part, arranging a second mold part which is substantially transparent to laser radiation on the first mold part, and irradiating the two mold parts along the contour of a welding seam to be produced using a machining laser such that the energy input produced by the machining laser is controlled by a controller on the basis of the generated absorption profile of the first mold part.
