Abstract: A method for laser welding a first and an at least partially overlapping second workpiece sheet along a machining path includes: detecting a distance from a reference to the first and to the second sheet at a plurality of positions; determining a gap width between the sheets based on the distances; and welding together the sheets by radiating the beam along the path and forming a weld seam. The laser beam power is adapted to the respective gap width along the path. A laser machining system for welding sheets using a machining laser beam includes: a distance measuring device detecting a distance to a first and second sheet at a plurality of positions; deflection optics guiding the beam along a machining path; and a control device determining a gap width between the sheets based on the distances. The control device adapts the laser beam power to the respective gap width.

Abstract: A method for determining a position of a workpiece for a laser machining process includes the steps of: radiating a measurement beam to at least one workpiece and a support device surrounding the workpiece along at least one first and along at least one second measurement path, the first path forming a predetermined angle with the second path; acquiring a portion of the radiated measurement beam, reflected by the support device and the workpiece, along the first and along the second measurement path and generating a corresponding measurement signal, the support device and the workpiece comprising a reflectivity different from each other; and determining a position of the workpiece based on the measurement signal. A method for machining a workpiece by a laser beam includes the method for determining the position of the workpiece. An apparatus for determining a position of a workpiece is configured for conducting the methods.

Abstract: A method of analyzing a welded connection during laser welding of workpieces includes acquiring a first measurement signal for a process radiation generated during laser welding, acquiring a second measurement signal for a laser radiation reflected by the workpieces, determining whether there is a gap between the workpieces based on the first measurement signal, and when it is determined that there is a gap, determining based on the second measurement signal whether there is a welded connection.

Abstract: A method is provided for analyzing a weld seam formed by a laser welding process, said method including thermally exciting the weld seam by radiating at least one laser pulse onto the weld seam, acquiring a decay characteristic of a thermal radiation emitted by the weld seam, and determining whether a welding defect is present based on an evaluation of the acquired decay characteristic. Furthermore, a laser machining system for analyzing a weld seam formed by a laser welding process between at least two workpieces is provided.

Abstract: A server computer. The server computer comprises a processor, a non-transitory memory, a application comprising JavaScript instructions stored in the non-transitory memory, a runtime stored in the non-transitory memory, and a native agent module stored in the non-transitory memory. When executed by the processor, the runtime provides a JavaScript execution environment for executing the application and an instrumentation application programming interface (API). When executed by the processor outside of the runtime, the native agent module monitors memory buffers allocated to the application based on accessing the instrumentation API of the runtime, executes an event loop that sends an interrupt to the runtime, and provides reporting based on monitoring the memory buffers and the interrupt sent to the runtime to a management layer external to the server computer.
