    摘要： A metal fabrication system includes one or more sensors configured to transmit a first signal relating to a first condition of an environment of the metal fabrication system, processing circuitry coupled to the one or more sensors, and a feedback device coupled to the processing circuitry. The processing circuitry is configured to determine the first condition of the environment based at least in part on the first signal and to compare the first condition to a first threshold. The feedback device is configured to provide a first notification when the first condition satisfies the first threshold.

    摘要： A tool driving section of a friction stir spot welding device is configured to advance and retract each of a pin member (11) and a shoulder member (12). A tool driving control section is configured to control the tool driving section such that an absolute value of a tool average position Tx defined by a following equation: Ap·Pp + As·Ps = Tx, where Ap is a cross-section area of a front end surface of the pin member (11), As is a cross-section area of a front end surface of the shoulder member (12), Pp is a press-fit depth of the pin member (11) press-fitted from a front surface of an object to be welded (60), and Ps is a press-fit depth of the shoulder member (12) press-fitted from the front surface of the object to be welded (60),is small. Thus, especially in a double acting friction stir spot welding, excellent welding quality can be accurately achieved according to welding conditions, and an internal cavity defect can be prevented or suppressed.

    摘要： The present invention provides a novel method and system for tool breakage detection during the friction stir welding procedure on an automated friction stir welding machine. The object of this invention is the integration of an accelerometer sensor which detects tool breakage events in real time and triggers a preprogrammed reaction of CNC controller. In this way, a complete destruction of welding tool is prevented. Another object of the present invention is to provide an automatic reaction of CNC controller that is triggered by an error signal and consequently prevents N.O.K parts with welding faults from entering further production steps.

    摘要： Electric spindle with axial force control intended for friction welding and other uses, of the type used industrially for the automated welding of metal plates or metal elements, characterized in that it incorporates, inside the body of the electric spindle, a force sensor, associated with the tool by means of an internal shaft that can move axially and which, via an electromechanical actuator, allows the real-time local adjustment of the height of the tool above the material to be welded, such as to maintain a constant, controlled force during the welding and/or machining processes.
    The main advantage of the invention that is presented is that the height is corrected according to the force, automatically in the electric spindle itself, with much greater precision and speed, thereby providing more uniform welding results without irregularities.
