  • Patent number: 12076824
    Abstract: Some examples relate to a welding-type monitoring system configured to track parts, production, and/or operations within a welding-type production cell. In some examples, the monitoring system comprises a computing system, one or more tags attached to one or more first items, and/or one or more tag readers attached to one or more second items. In some examples, the one or more tags store data relating to the first items, and the one or more tag readers are configured to read the data using a close proximity communication protocol when in range of the one or more tags. After the tag reader reads the data from the tag, the computing system may determine whether one or more workflow events are associated with the data. If so, the computing system may execute an event script corresponding to the workflow event.

  • Publication number: 20240149449
    Abstract: Disclosed example robotic welding systems include: a robotic manipulator configured to manipulate a welding torch; a first input device attached to the robotic manipulator and configured to receive rotational and translational inputs; a second input device attached to the robotic manipulator and configured to receive a masking input; and a robot control system, comprising: a processor; and a machine readable storage medium comprising machine readable instructions which, when executed by the processor, cause the processor to: in response to activation of the masking input via the second input device, masking at least a portion of the inputs received via the first input device; and in response to inputs to the first input device, move the robotic manipulator according to the inputs and based on whether the inputs are masked.

  • Publication number: 20240149457
    Abstract: Disclosed example robotic welding systems include: a robotic manipulator configured to manipulate a welding torch; and a robot control system, comprising: a processor; and a machine readable storage medium comprising machine readable instructions which, when executed by the processor, cause the processor to, during a robotic welding procedure involving the robotic manipulator: prior to initiating an arc as part of the robotic welding procedure, identify an arc warning event; in response to the arc warning event, output at least one of a visual notification or an audible notification proximate to the robotic manipulator; and control the robotic manipulator to perform the robotic welding procedure involving initiating the arc using the welding torch.

  • Publication number: 20210065140
    Abstract: Systems and methods for using drones in dispersed welding applications are disclosed. In some examples, drones may be used in large and/or dispersed welding environments to quickly navigate the large distances and/or reach areas that might be more difficult for a person to reach. In some examples, the drones may use one or more attached devices to locate, identify, and/or collect information from welding equipment, welding workpieces, and/or welds within a (e.g., large and/or dispersed) welding environment.

  • Patent number: 10725299
    Abstract: An example head-worn device includes a camera, a display device, weld detection circuitry, and pixel data processing circuitry. The camera generates first pixel data from a field of view of the head-worn device. The display device displays second pixel data to a wearer of the head-worn device based on the first pixel data captured by the camera. The weld detection circuitry determines whether a welding arc is present and generates a control signal indicating a result of the determination. The pixel data processing circuitry processes the first pixel data captured by the camera to generate the second pixel data for display on the display device, where a mode of operation of said pixel data processing circuitry is selected from a plurality of modes based on said control signal.
