The invention pertains to a laser machining system includes first deflection optics, second deflection optics, and a coupling device. The first deflection optics deflect a machining laser beam in two directions in space. The second deflection optics deflect a measuring beam in two directions in space independently of the machining laser beam. The coupling device is arranged in a beam path of the machining laser beam and couples the measuring beam into the beam path of the machining laser beam.

A laser processing apparatus may include: a laser generator configured to generate a laser beam; a stage configured to support a target object; at least one supply nozzle on the stage to eject an air toward the stage; a suction unit configured to inhale external air; and a suction structure on the stage and adjacent to the at least one supply nozzle. The suction structure may include a suction hole connected to the suction unit to inhale the external air. The suction structure may include an inclined surface in which the suction hole is defined. The suction structure may include a first surface adjacent to the supply nozzle, and an opening may be defined in a region of the first surface adjacent to a bottom surface. A distance between the inclined surface and the target object may be less than or equal to a height of the opening.

A weldment includes a first component, a second component, and a weld joint coupling the first and second components together. The weld joint forms a heat affected zone in the first component and creates residual tensile stress in the first component. The first and second components cooperate to define a pocket configured to position a highest magnitude of the residual tensile stress in the first component in a location that is outside of the heat affected zone of the first component.

The present invention is a laser processing device wherein adhesion of fumes to a lens can be effectively avoided. The laser processing device is provided with a laser scanner provided with protective glass on a laser output opening, and a cylindrical member having a through path through which the laser output via the protective glass passes formed on the center side in the direction of the radius. A cylindrically shaped filter is disposed on an inside wall part of the cylindrical member facing the through path. The cylindrical member discharges a gas into the through path from the filter.

A unit for the regulation for control of a fluid pressure, having at least one housing section and a switching film connected to the at least one housing section. A chemically inert, non-rubber-like PTFEswitching film switching film is disposed in the valve housing and switches at pressure differences of 1 mbar to 250 mbar for regulating, opening or blocking a flow of a fluid from the inlet to the outlet. The switching film is formed of a fluorine and carbon containing polymer material. The switching film has a plate-shaped flat body with a bending region and has a central closure region surrounded by the bending region. The bending region, when switching the switching film, moves the central closure region relative to a valve seat of the valve housing in an axial direction of the plate-shaped flat body toward or away from the valve seat by a stretch free or low-stretch bending movement.
