Latest Patents

Among his latest patents are two innovative methods related to defect detection in laser machining. The first patent describes a method for detecting defects during a laser-machining process. This method involves moving a laser beam along a predefined path over multiple workpieces to generate a weld seam or cutting gap. It includes detecting radiation emitted or reflected by the workpieces using a two-dimensional detector field. The process selects specific detection field sections based on laser beam control data or actual-position data, evaluates the detected radiation, and determines the presence of defects at the weld seam or cutting gap.

The second patent focuses on detecting defects in a weld seam during laser welding. This method performs a two-dimensional detection of radiation emitted by a solidified molten mass adjacent to a liquid melting bath. It determines characteristic values for heat dissipation in the solidified molten mass by evaluating the detected radiation along profile sections. Defects in the weld seam are identified by comparing these characteristic values with reference values.
