摘要： A FLASH TRAP SITUATED BETWEEN A MAJOR WELD AND A MINOR WELD PRODUCED BETWEEN TWO WELD MEMBERS WHICH ARE FRICTION OR INERTIA WELDED TOGETHER. THE TRAP COMPRISES A RADIAL VOID INTO WHICH THE FLASH FROM THE MAJOR WELD CAN EXPAND. THE OPPOSITE END OF THE VOID IS CLOSED
BY THE MINOR WELD WHICH IS PERFORMED UTILIZING SUCH PARAMETERS AS TO PRODUCE NO FLASH THEREFROM.-

摘要： A friction welding apparatus includes a support, a headstock carrying a rotatable chuck for holding a first workpiece to be welded to a second static workpiece, the headstock being mounted on the support for movement axially of the chuck. Piston and cylinder type displacement means are connected between the headstock and the support for producing axial movement of the headstock and the chuck is provided with rotary drive means incorporating a shaft passing coaxially through the cylinder of the piston and cylinder device.

摘要： A friction welding machine has a direct center drive means wherein the rotor of the drive means functions as the workpiece holding spindle for one or more center driven workpieces; the machine is adapted for use as a dual welder wherein a movable tailstock is employed on each side of the center drive means and also for use with a single tailstock on one side of the center drive and a supplemental thrust bearing means on the other side of the center drive. One embodiment of the machine incorporates a free-floating center drive means. A special workpiece holding device is also provided wherein a special adjustable toggle linkage arrangement is adapted to provide gripping means for a large number of variously sized workpieces.

摘要： A POWER AND DRIVE SYSTEM FOR AN INERTIA WELDING MACHINE HAVING A POWER SECTION CONNECTED TO A GEAR TRAIN THROUGH A SELECTIVELY ACTUATABLE CLUTCH AND BRAKE. THE DRIVE TRAIN PORTION IS CONNECTED TO THE ROTATING SPINDLE OF THE MACHINE THROUGH A ONE-WAY CLUTCH. WHEN THE MACHINE REACHES WELDING SPEED,THE SELECTIVELY ACTUATABLE CLUTCH IS DEACTIVATED, THE BRAKE IS ACTUATED, AND THE ONE-WAY CLUTCH ALLOWS THE SPINDLE TO CONTINUE TO ROTATE WITHOUT HAVING THE FLYWHEEL OR DRIVE TRAIN MASS WK2 ADDED THERETO.

摘要： Ceramic substrates, and the like, are parted by reflecting a focused laser beam off a mirrored surface so that the focal point of the beam impinges upon the lower surface of the substrate at an extreme edge thereof. The impingement of the focused beam creates a precisely defined localized fracture in the substrate. Next, the substrate is displaced, relative to the laser beam, to intercept the beam before it is reflected from the mirrored surface. The laser beam is now intercepted by the upper surface of the substrate before the beam reaches its focal point, resulting in the beam energy being distributed over a larger area of the substrate. As the relative displacement of the laser beam with respect to the substrate continues, the localized fracture is controllably propagated along the substrate to part the substrate.

摘要： A hydraulic drive system for accelerating the flywheel of a friction welder to welding speed includes a single pump and a number of constant displacement motors. Each motor is connected to drive the flywheel so long as fluid is supplied to that motor from the pump. The drive system has a valve and manifold arrangement such that fluid is supplied from the pump to the motors in parallel at start up to provide the maximum torque. As the flywheel accelerates, the flow of fluid from the pump to selected ones of the motors is discontinued and is redirected to the remaining motors to provide rapid acceleration with a system that approaches a constant horsepower supply of power.

摘要： A friction welding machine is adapted to weld workpieces having a wide range of diameters by utilizing a unidirectional drive means, such as a one-way overrunning clutch, which is disposed between rotatable components of the machine and a rotatable workpiece holding spindle. The unidirectional drive means provides a driving connection between the rotatable components and the spindle when relative motion therebetween is in one direction and prevents a driving connection when relative motion therebetween is in an opposite direction. One embodiment of the invention has a dual-spindle arrangement in which the spindles may be operated independently or together to provide a machine which is capable of friction welding workpieces having a large range of diameters. The dual-spindle arrangement also permits workpieces of relatively large diameter to be loaded and unloaded from the machine while the input energy components of the machine are being accelerated to welding velocity.

摘要： A system and method for microscopic spot welding with laser radiation. The invention, having particular relationship to microscopic multiple spot welding, employs mode selection of laser emitted radiation. A number of objective lenses are positioned in a diverging mode selected laser beam and the lenses are arranged within the spread of the beam in relative geometrical positions corresponding to the number and positions of spots requiring welding. Auxiliary lens means may be employed to direct the diverging laser beam toward the object to obtain proper spacing of the welding spots. The system produces a multiplicity of microscopic welding spots on the object each of a minimum size governed by the size of the Airy disc produced by its respective objective lens.
