摘要： A peening method which can sufficiently improve fatigue properties of a lap fillet welded joint having a thin steel sheet as a base sheet, in which a knocking pin having a predetermined shape is continuously knocked as a series of knocking toward a direction inclined relative to the welding direction, the series of knocking is repeatedly performed in the welding direction, at that time, a knocking mark group made of a plurality of knocking marks formed by the series of knocking is superimposed on at least a part of an adjacent knocking mark group while an end part in the direction orthogonal to the welding direction of the knocking mark group is separated from an end part in the direction orthogonal to the welding direction of the adjacent knocking mark group.

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： A suction bucket for a seabed foundation for an offshore facility is provided. The suction bucket is arranged for being embedded into a marine sediment. The suction bucket includes a lid and a sidewall. The sidewall is segmented into a first circumferential segment and at least a second circumferential segment. The first circumferential segment is connected with the second circumferential segment. The first circumferential segment and the second circumferential segment are attached to the lid of the suction bucket. Furthermore, the first circumferential segment and the second circumferential segment each contains at least one substantially planar section. Furthermore, a method to manufacture a suction bucket for a seabed foundation for an offshore facility is also provided.

摘要： A welding system includes a welding torch, a power supply, one or more sensors, and a controller is provided. The welding torch advances an electrode toward a workpiece in a first direction. The power supply provides a flow of electricity to the electrode for generating a welding arc between the electrode and the workpiece. Generating the welding arc generates a weld puddle behind the welding arc as the electrode moves in the first direction. The sensor generates a voltage output signal based on the amount of light received from the weld puddle. The controller is communicatively coupled with the sensor to receive the voltage output signal, and the sensor controls a welding parameter of the welding system based the voltage output signal.

摘要： Hybrid manual and automated welding systems and methods are described. A hand-held welding tool is manually positioned to engage a workpiece. A weld is started from an initial position based on a first manual operator event. A welding heat source is automatically or autonomously moved along the weld relative to the workpiece from the first position to a second position relative to the workpiece during welding.

摘要： An assembly to connect together first and second sheet members. The assembly includes a pressure device that applies pressure to the sheet members while the sheet members are in an overlapping arrangement and positioned on a support platform. A sensing system that includes one or more thin film pressure sensors detects the positions of the leading and trailing edges. A connection device connects the members together in an overlapping arrangement.

摘要： A method is used to manufacture an end effector of a surgical instrument. The end effector includes first and second opposing jaws. The first jaw includes a body and an elongate cap. The method includes providing the elongate cap and the body of the first jaw of the end effector. The body includes an elongate channel and at least one alignment feature. The method also includes aligning the elongate cap with the elongate channel that extends completely through the body using the at least one alignment feature of the body that is disposed adjacent the elongate channel. The method also includes welding the elongate cap onto the body to at least partially enclose the elongate channel.
