  • Laser welding of workpieces by machine
    Patent number: 10399173
    Abstract: A method for machine processing, in particular for machine welding processing of workpieces, in particular of plate-like workpieces, tubes and/or profiles, by means of a thermal processing beam, in particular by means of a processing beam is described, wherein the processing of the workpiece is carried out with a relative movement between the processing beam and the workpiece, wherein a process gas is fed to a processing zone in a settable quantity of process gas per unit of time. After a stored stabilization time, in which the processing of a workpiece is continued with a relative movement between the processing beam and the workpiece, a quantity of process gas per unit of time is automatically reduced. Further a control apparatus of a setting device for process gas feed according to such a method is described.
