  • Publication number: 20250083317
    Abstract: A welding system includes a robot having a movable arm. A robot controller is operatively connected to the robot. A welding torch is attached to the robot. A welding power supply is operatively connected to the torch. A teach pendant is in communication with the robot controller and includes a user interface application configured for programming a plurality of welding points of a welding operation performed by the robot, and is configured for programming a workpiece search for a physical location of a workpiece. The user interface application is further configured to receive input of a search start point that is offset from the physical location of the workpiece, and to display a prompt to calibrate the search. Upon receiving user input to calibrate the search, the physical location of the workpiece is automatically detected and a calibrated indication is displayed confirming that the search is currently calibrated.

  • Publication number: 20250083322
    Abstract: An embodiment includes a robotic welding system for generating a motion program, having a programmable robot controller of a robot having a computer processor and a computer memory. The programmable robot controller is configured to digitally record, in the computer memory, a plurality of spatial points along an operator path in a 3D space taken by a calibrated tool center point (TCP) of the robot as an operator manually moves a robot arm of the robot along the operator path from a start point to a destination point within the 3D space. The programmable robot controller is also configured to identify and eliminate extraneous spatial points from the plurality of spatial points as digitally recorded, leaving a subset of the plurality of spatial points as digitally recorded, where the extraneous spatial points are a result of extraneous movements of the robot arm by the operator.

  • Publication number: 20240326178
    Abstract: A welding system includes a collaborative robot, a robot controller, a welding torch having an end located at a tool center point (TCP), a welding power supply, and a teach pendant. The teach pendant includes a UI application configured for programming welding points and parameters. In a first operation mode, the UI application displays the plurality of welding points in a list that includes a highlighted closest welding point having a three-dimensional position that is closest to the TCP. The highlighted closest welding point automatically updates upon manual movement TCP. In a second operation mode, the list includes a highlighted selected welding point, and the UI further displays a selector button that shows a straight line distance of the TCP to a three-dimensional position of the highlighted selected welding point. Activation of the selector button causes the TCP to move to the position of the highlighted selected welding point.

  • Publication number: 20240269760
    Abstract: In one embodiment, weld torch angle tools are provided to present an operator with the work angle and travel angle measured as taught in the weld point. The operator is presented with buttons to make small adjustments which the robot will move to in live updates to independently tune each angle. If the base plate is tilted, a workflow is provided to the operator to teach that tilt to the robot, allowing the measured angles and axes to be adjusted accordingly. This allows the operator to accurately dial in the exact angle measures specified for a given weld and to visually confirm the validity of the weld point as adjusted, to prevent any unexpected collision or robot reach issues.

  • Patent number: 11847298
    Abstract: Provided is an electric arc generation system comprising a robot, an electric arc torch attached to the robot, a power supply configured to provide an electrical power output to the torch, and a user interface for adjusting a plurality of power supply parameters. The user interface comprises a display. The system includes a processor configured to receive respective settings of the plurality of power supply parameters, and configured to analyze the settings of the plurality of power supply parameters and control the display to display a pictograph warning associated with a current parameter setting, based on a result of analyzing the settings of the plurality of power supply parameters. Said pictograph warning graphically indicates an adjustment direction for the current parameter setting. The processor is configured to automatically adjust one or more of the settings of the plurality of power supply parameters based on a predetermined operating angle of the torch.

  • Publication number: 20230390918
    Abstract: A method of programming multiple weld passes in a collaborative robot welding system to perform multi-pass welding is provided. A root pass is programmed for a first weld seam by manually positioning a welding torch and automatically recording root pass position and angle data. Secondary passes for the first weld seam are also programmed. The tip of the welding torch is positioned at a start point and a stop point for each secondary pass. The start and stop position data of the start point and the stop point are automatically recorded for each secondary pass. Numerical position and angle offset data are automatically calculated. The root pass position and angle data and the offset data are stored as a multi-pass template. The template is translated and applied to a weld reference frame of a second weld seam to aid in programming secondary passes for the second weld seam.

  • Publication number: 20230390927
    Abstract: A method of correcting angles of a welding torch positioned by a user while training a robot of a robotic welding system is provided. Weldment depth data of a weldment and a corresponding weld seam is acquired and 3D point cloud data is generated. 3D plane and intersection data is generated from the 3D point cloud data, representing the weldment and weld seam. User-placed 3D torch position and orientation data for a recorded weld point along the weld seam is imported. A torch push angle and a torch work angle are calculated for the recorded weld point, with respect to the weldment and weld seam, based on the user-placed torch position and orientation data and the 3D plane and intersection data. The torch push angle and the torch work angle are corrected for the recorded weld point based on pre-stored ideal angles for the weld seam.

  • Patent number: 11731208
    Abstract: Embodiments of systems and methods of additive manufacturing are disclosed. In one embodiment, a computer control apparatus accesses multiple planned build patterns corresponding to multiple build layers of a three-dimensional (3D) part to be additively manufactured. A metal deposition apparatus deposits metal material to form at least a portion of a build layer of the 3D part. The metal material is deposited as a beaded weave pattern, based on a planned path of a planned build pattern, under control of the computer control apparatus. A weave width, a weave frequency, and a weave dwell of the beaded weave pattern may be dynamically adjusted during deposition of the beaded weave pattern. The adjustments are under control of the computer control apparatus based on the planned build pattern, as a width of the build layer varies along a length dimension of the build layer.
