A remote controlled, tele-operated welder includes a multi-axis robot arm, video cameras, sensors a specialized control station that allows an operator to perform flood-fill welding operations at a remote location to avoid the heat, smoke and other environmental effects produced through typical flood-welding operations. The operator accesses the control unit (OCU) using a GUI and mouse, keyboard, joystick, or other custom controls, and observe the piece via the cameras (visual, thermal, or other) placed in the welding station via a feed displayed on the OCU display(s). Audio, video, and/or tactile feedback may be provided to indicate arm, welder, or other system status, for collision warning and arm motion singularity avoidance. Augmented reality informational graphic/textual overlays may provide guidance to an operator, and the apparatus may further include the ability to repeat series of steps needed to handle flood-weld on a given piece, repeatedly across many pieces.

LASER PROCESSING METHOD, LASER PROCESSING DEVICE, AND METHOD FOR PRODUCING LASER PROCESSED PRODUCT

A workpiece having a first plate-shaped part and a second plate-shaped part connected to the first plate-shaped part in a direction to cross the first plate-shaped part is cut with a laser beam. A cutting line across the first plate-shaped part and the second plate-shaped part is set. In the second plate-shaped part, a notch portion that opens to a tip end portion of the second plate-shaped part and is along the cutting line is formed by cutting with the laser beam so that a cutout piece that is cut out by forming the notch portion is divided into a tip end portion and a base portion. The first plate-shaped part is cut along the cutting line by irradiation with the laser beam from one direction.

A laser processing system includes an irradiation device that irradiates a laser beam to a workpiece and includes a housing, a box positioned inside the housing and housing at least a part of a path of the laser beam, and at least one infrared sensor positioned inside the housing and around the box.

Method for measuring the distance between a workpiece and a machining head of a laser machining apparatus

According to a method for measuring the distance between a workpiece and a machining head of a laser machining apparatus, a machining head is provided, which has a housing that has an interior and an opening for emergence of the laser radiation from the machining head. The laser radiation is directed on to the workpiece, after it has passed through the interior and the opening. An object beam is directed on to the workpiece by a light source of an optical coherence tomograph in such a manner that the object beam passes through the interior and the opening before being incident upon the workpiece. In addition to the object beam, a measuring beam passes through the interior. The measuring beam is used to compensate falsifications of the measured distance that have been caused by pressure fluctuations in the interior. The measuring beam in this case may be reflected at a reflective face that is formed on an inner face of an outlet nozzle that comprises the opening, which inner face delimits the interior.

Processing 3D shaped transparent brittle substrate

Methods are provided for laser processing arbitrary shapes of molded 3D thin transparent brittle parts from substrates with particular interest in substrates formed from strengthened or non-strengthened Corning Gorilla® glass (all codes). The developed laser methods can be tailored for manual separation of the parts from the panel or full laser separation by thermal stressing the desired profile. Methods can be used to form 3D surfaces with small radii of curvature. The method involves the utilization of an ultra-short pulse laser that may be optionally followed by a CO.sub.2 laser for fully automated separation.
