    摘要： A robotic electric arc welding system includes a welding torch, a welding robot configured to manipulate the welding torch during a welding operation, a robot controller operatively connected to the welding robot to control weaving movements of the welding torch along a weld seam and at a weave frequency and weave period, and a welding power supply operatively connected to the welding torch to control a welding waveform, and operatively connected to the robot controller for communication therewith. The welding power supply is configured to sample a plurality of weld parameters during a sampling period of the welding operation and form an analysis packet, and process the analysis packet to generate a weld quality score, wherein the welding power supply obtains the weave frequency or the weave period and automatically adjusts the sampling period for forming the analysis packet based on the weave frequency or the weave period.

    摘要： A torch for use by a robot. The torch has a body that can be connected to an arm of the robot. A first actuator on the body can be activated by a user to initiate a recording cycle at a starting point of a desired welding or cutting path and to terminate the recording cycle at an ending point of the path. A second actuator on the body can be activated by the user to indicate way points from the starting point to the ending point as the user moves the torch along the path. The first actuator sends first information to a robot controller, operatively connected to and located remotely from the robot, to initiate and to terminate the recording cycle at the controller. The second actuator device sends the way points as second information to the controller to be recorded at the controller during the recording cycle.

    摘要： In a fillet welded joint a base material tensile strength is 980 MPa or more, a carbon equivalent is 0.36 or more and 0.60 or less, a tensile strength [MPa] is 1950 times or more of the carbon equivalent [wt %], a weld metal average carbon equivalent is 0.45 or more and 0.65 or less, and at a prescribed position below a surface of a weld toe, a Vickers hardness HVbond at a boundary between the weld metal and a heat affected zone, an average value HVwmt of the Vickers hardness of the weld metal in a position 0.1-mm or more and 0.3-mm or less to the weld metal side of the boundary, and an average value HVhaz of the Vickers hardness of the heat affected zone in a position 0.1-mm or more and 0.3-mm or less to the heat affected zone side of the boundary satisfy HVbond≤HVwmt, HVbond≥HVhaz-50, and HVhaz≤350.
