A laser machining system according to one embodiment of the present disclosure is provided with: a laser machining head having a laser optical system that has a Galvano scanner, and a tracking sensor for detecting a joint in a workpiece; a machining robot for positioning the laser machining head; a holding robot for holding the workpiece; a machining robot control unit for controlling the machining robot so as to move the laser machining head along a joint according to a design; a holding robot control unit for controlling the holding robot so as to move the workpiece such that the distance between the position of the joint as detected by the tracking sensor and the middle of the detection range of the tracking sensor remains within a prescribed range; and a Galvano scanner control unit for controlling the Galvano scanner so as to set the irradiation position of the laser light at a position that is offset by the movement amount of the workpiece from the position of the joint as detected by the tracking sensor.

A laser welding system for joining first and second thermoplastic workpieces, and including a clamp, an actuator, and a laser source. The clamp includes first and second clamping structures positioned together to engage opposite sides of the workpieces when they adjoin each other. The first clamping structure has a non-flat or irregular surface, facing the first workpiece. The actuator causes the clamping structures to press the first and second workpieces together. The laser source applies laser radiation having a wavelength of 2 microns toward the workpieces to be joined, while they are pressed together by the clamp, to melt irradiated portions of the workpieces to one another. The first clamping structure transmits substantially all of the energy of the laser radiation through the material. The first workpiece has a non-flat or irregular surface facing the first clamping structure, which substantially conforms with the surface of the first clamping structure.

A robotic welding system comprises a supporting arm for attaching to a repositionable support structure, the supporting arm comprising a first mounting portion connectable to the repositionable support structure, and a second mounting portion rotatably coupled to the first mounting portion. A yaw rotary actuator rotates the second mounting portion about a yaw axis. A welding arm comprises a third mounting portion rotatably coupled to the second mounting portion of the supporting arm. A pitch rotary actuator rotates the third mounting portion about a pitch axis generally perpendicular to the yaw axis. A roll rotary actuator rotates a torch holder shaft about a roll axis generally perpendicular to the pitch axis. The shaft has a torch mounting portion for mounting a welding torch at an end thereof. A controller is operably coupled to the actuators to cause the welding torch to execute a welding pattern.

A manipulator device such as a robot arm that is capable of increasing manufacturing throughput for additively manufactured parts, and allows for the manipulation of parts that would be difficult or impossible for a human to move is described. The manipulator can grasp various permanent or temporary additively manufactured manipulation points on a part to enable repositioning or maneuvering of the part.

Laser cutting on a plated steel sheet is executed by cutting the plated steel sheet by irradiating the plated steel sheet covered with a plate metal with laser light at a wavelength in a 1 micrometer band; and emitting assist gas onto a cut surface of the plated steel sheet, the cut surface being formed in the step of cutting, to make the plate metal fused by irradiation of the laser light flow to the cut surface so as to cover the cut surface with the plate metal.

Workpiece tools and techniques are described. In one example, a workpiece tool includes different side panels that provide surfaces for workpiece alignment. Further, a workpiece tool includes apertures that can align with a work surface such as a welding table. An adjustable tool is also described that includes a tool body and a slidable member that is slidable relative to the tool body. The slidable member, for instance, represents a measurement tool that can be used to measure object dimensions. Further, the tool body includes different side panels that are arranged to enable a variety of different usage scenarios such as include different positions of the slidable member relative to an adjacent object and/or surface.

The invention relates to a device for checking for foreign parts and/or deposits on support elements of a worktable, wherein the support elements are provided to support a flat workpiece for cutting with a laser or a water jet, wherein the support elements are arranged parallel to one another and have a first distance from one another, comprising: a sensor for detecting the foreign parts and/or the deposits in the space between two respective support elements.

An interpolation parameter calculation unit calculates an interpolation parameter of a predetermined interpolation calculation formula based on a first plurality of coordinate values input by means of a coordinate input unit and constituting a coordinate pattern for determining a locus pattern of one cycle when a laser beam is vibrated. A locus pattern calculation unit calculates a second plurality of coordinate values constituting the locus pattern based on an interpolation parameter, respective amplitudes of the locus pattern in an x-axis direction that is a moving direction of a processing head and a y-axis direction that is a direction orthogonal to the x-axis direction, a frequency of the locus pattern, and a control cycle of a beam vibration mechanism for vibrating the laser beam.

A method for connecting two components with the aid of a laser weld seam. The two components are situated one above the other in a joining area. The first component is pressed in the direction of the second component with the aid of a clamping device. A laser beam impacts the first component on the side facing away from the second component and at least indirectly fusing material of the two components.

A processing method includes a holding step of holding a workpiece by a chuck table including a holding surface that holds the workpiece in an upper surface and a sheet covering step of covering the upper surface of the chuck table in addition to the workpiece by a sheet having transmissibility. The processing method also includes a close contact step of generating a suction force for the holding surface of the chuck table and reducing the pressure on a region covered by the sheet to bring the workpiece into close contact with the upper surface of the chuck table by an atmospheric pressure applied to the sheet and a modified layer forming step of positioning the focal point of a laser beam inside the workpiece through the sheet and irradiating the workpiece with the laser beam to form a modified layer.
