  • Patent number: 11072034
    Abstract: The invention described herein generally pertains to a system and method for collecting one or more welding parameters in real time during creation of one or more welds using a welding sequence. The one or more welding parameters can be associated with a particular welding sequence. Moreover, based on the one or more welding parameters collected, a modeled welding parameter can be generated to increase quality, efficiency, and the like. A collection component collects real time welding parameter data from which a quality manager component creates a modeled welding parameter. The modeled welding parameter can be employed for the welding sequence to monitor or track the welding parameter during a subsequent weld.

    Abstract: Embodiments of robotic systems are disclosed. In one embodiment, a robotic system includes a tool used in a manufacture process on a workpiece, and an arm having an attachment point. The arm moves the tool, in multiple degrees of freedom during the manufacture process. A robot controller controls movement of the arm based on motion parameters to perform the manufacture process via the tool. A path planner component generates the motion parameters used to perform the manufacture process while avoiding robot collision conflicts. The path planner component includes a reach configuration component including data related to physical attributes, motion attributes, kinematics, and limitations of the robotic system. The path planner component also includes a collision avoidance evaluator to, using the reach configuration component, determine if an anticipated robot path results in any robot collision conflicts.

  • Patent number: 11027362
    Abstract: A system and method to correct for height error during a robotic additive manufacturing process. One or both of an output current, output voltage, output power, output circuit impedance and a wire feed speed are sampled during an additive manufacturing process when creating a current layer. A plurality of instantaneous contact tip-to-work distances (CTWD's) are determined based on at least one or both of the output current, output voltage, output power, output circuit impedance and the wire feed speed. An average CTWD is determined based on the plurality of instantaneous CTWD's. A correction factor is generated, based on at least the average CTWD, which is used to compensate for any error in height of the current layer.

  • Patent number: 11007594
    Abstract: A system and method to correct for deposition errors during a robotic welding additive manufacturing process. The system includes a welding power source to sample instantaneous parameter pairs of welding output current and wire feed speed in real time during a robotic welding additive manufacturing process while creating a current weld layer of a 3D workpiece part. An instantaneous ratio of welding output current and wire feed speed are determined for each instantaneous parameter pair. A short term running average ratio is determined based on the instantaneous ratios. A relative correction factor is generated based on at least the short term running average ratio and is used in real time while creating the current weld layer to compensate for deviations in a deposit level from a desired deposit level for the current weld layer.

  • Patent number: 11007595
    Abstract: An electric arc welder and a method for performing a pulse welding process producing reduced spatter. The welder produces a current between an advancing electrode and a workpiece. The welder includes a short-detecting capability for detecting a short condition upon occurrence of a short circuit between the advancing electrode and the workpiece. The welder may also include a switching module in the welding circuit path of the welder having an electrical switch and a resistive path. Times of occurrence of short intervals can be tracked and a blanking signal can be generated based on the tracked short intervals to anticipate a next short interval in a next pulse period of the pulsed welding process. The blanking signal can be used to reduce a welding current in the welding circuit path by introducing additional resistance into the welding circuit path via the switching module, for example.
