Publication number: 20170021446Abstract: A method and apparatus for ultrasonic in-process monitoring and feedback of resistance spot weld quality uses at least one transducer located in the electrode assembly transmitting through a weld tip into an underway weld. Analysis of the spectrum of ultrasonic waves provides the operator with an indication of the size, thickness, location, dynamics of formation and quality of the spot weld. The method presents a fundamentally new physical approach to the characterization of the spot weld quality. Together with transmission mode it includes new modes of operation of ultrasonic probes such as a reflection mode and simultaneous use of transmission and reflection modes, and a new physical interpretation of the signal analysis results.Type: ApplicationFiled: February 15, 2016Publication date: January 26, 2017Inventors: Roman Gr.

Publication number: 20170021450Abstract: A method and device for laser machining a substrate, involves deflecting the laser radiation using a galvanometer scanner and an electro-optical deflector. The laser radiation thus deflected multiple times is then directed at a machining position on the substrate. By superposing an additional beam deflection by the electro-optical deflector onto the advance movement in the machining direction, which deflector is operated with steady oscillation excitation for this purpose, the resultant beam deflection follows a circular revolving path. In the process, the series of pulses of a pulsed radiation source is restricted to individual or a plurality of machining positions on the substrate, and forms for example a cutting front so as to thus quickly and reliably produce a kerf having the desired width.Type: ApplicationFiled: July 25, 2016Publication date: January 26, 2017Inventors: Roman Ostholt, Udo Buenting, Norbert Ambrosius, Malte Schulz-Ruhtenberg

Publication number: 20170021454Abstract: Systems and methods for multiple beam additive manufacturing use multiple beams of light (e.g., laser light) simultaneously to expose layers of powder material in selected regions until the powder material fuses to form voxels, which form build layers of a three-dimensional structure. The light may be generated from selected light sources and coupled into an array of optical fibers having output ends arranged in an optical head such that the multiple beams are directed by the optical head to different locations on each of the powder layers. The multiple beams may provide distributed exposures forming a distributed exposure pattern including beam spots that are spaced sufficiently to separate the fused regions formed by each exposure. The multiple beams may be moved using various techniques (e.g., by moving the optical head) and according to various scan patterns such that a plurality of multiple beam distributed exposures form each build layer.Type: ApplicationFiled: June 10, 2016Publication date: January 26, 2017Inventors: Joseph DALLAROSA, William O'NEILL, David SQUIRES, Martin SPARKES, Andrew PAYNE
