Title: Marcel Schäfer: Innovator in Laser Welding Technology
Introduction
Marcel Schäfer is a prominent inventor based in Ditzingen, Germany. He has made significant contributions to the field of laser welding technology, holding 2 patents that focus on improving the quality and reliability of welds in various applications.
Latest Patents
One of his latest patents is titled "Detection of hot cracks in laser welding." This invention outlines methods for determining the quality of a weld in a workpiece welded by laser-beam welding. The process involves observing at least a partial region of a molten pool and its surrounding area during the welding process. The quality of the weld is assessed based on the observation results, which include monitoring a characteristic value that correlates with molten pool oscillation. This allows for the inference of the probability and frequency of hot cracks occurring at the weld.
Another notable patent is "Laser welding of steel with power modulation for hot-cracking prevention." This invention describes a method where a laser beam is moved relative to a workpiece to create a weld seam and form a weld pool. The laser power is modulated to prevent hot cracking, with specific parameters defined for the modulation frequency and amplitude. This innovative approach enhances the reliability of laser welding processes.
