    Abstract: A workpiece stack-up that includes at least a steel workpiece and an aluminum-based workpiece can be resistance spot welded by a spot welding method in which the welding current is controlled to perform one or more stages of weld joint development. When it is desired to terminate weld current flow and to solidify a liquid weld pool into a weld nugget (of mostly aluminum-based composition), additional cooling is applied to the outer surface of the aluminum-based workpiece around the contact area of the spot welding electrode engaging the surface of the aluminum-based workpiece surface. The additional cooling is applied and controlled so as to increase the rate of solidification of the liquid aluminum-based material and to control the direction of solidification of the weld nugget to better confine impurities, and the like, originally in the melt, at the surface of the steel workpiece.

The Steel part was 08Al steel. After cladding cold rolling with deformation of 55%±2%, the aluminum/steel cladding plates were annealed at 510˜535° C. for different times. Then simulated brazing process was performed to optimize the range of annealing time and temperature. The so produced Al/St cladding plates could not only effectively solve the low interface strength in Al/St cladding plates, but also meet the mechanical properties which were necessary for further processing of Al/St cladding plates.

    Abstract: A plug-in constant velocity (CV) joint is assembled to a powertrain component using a power tool. The CV joint and powertrain component connect via a splined shaft coupling with a snap ring interlock. External bi-directional thrust features on the joint and component engage first and second arms of the power tool after the splined shaft coupling is partially inserted by hand. The arms are relatively movable along a longitudinal direction, and an actuator selectively applies a compression force to the bi-directional thrust features adapted to fully insert the splined shaft coupling and engage the snap ring interlock. The power tool monitors the compression force to detect the full insertion. The actuator automatically applies a predetermined expansion force to the bi-directional thrust features to verify engagement of the snap ring interlock, wherein the predetermined expansion force is less than a force sufficient to disengage the snap ring interlock.

  • Publication number: 20170008149
    Abstract: In a trial peening step, a shot peening process is applied to a back face 40B of a mold 40 in which an opening of a closed-end water cooling hole 42 is formed. Next, in an evaluation step, compressive residual stress and surface roughness of a region shot-peened in the trial peening step are measured and an extent of shot peening treatment in the trial peening step is evaluated based on measurement results. Next, in a peening step, a surface of the water cooling hole 42 in the mold 40 is shot-peened under peening conditions set based on peening conditions for the trial peening step and on evaluation results produced in the evaluation step.

  • Publication number: 20170008151
    Abstract: For the shot peening of a pipe inner wall of a curved workpiece (200) having a workpiece bore (201), use is made of a flexible blasting abrasive feed hose (10) having blasting nozzle head (20). The latter is guided through a supporting element (30) which is applied to one workpiece end (203). The blasting abrasive feed hose (10) together with the blasting nozzle head (20) is introduced into the workpiece bore (201) and advanced along a blasting treatment section therein, and subsequently retracted into the supporting element (30) again. The blasting abrasive is emitted during the advancing movement and/or during the retraction movement. A blasting nozzle unit (100) suitable for carrying out the method comprises a flexible blasting abrasive feed hose (10) and a blasting nozzle head (20) connected to the blasting abrasive feed hose (10). The blasting nozzle head (20) has a plurality of nozzle openings (21) distributed around the circumference.

  • Publication number: 20170008152
    Abstract: A composite focus tube for a cutting head of an abrasive waterjet cutting machine includes a chemical vapor deposition diamond (CVDD) tube retained within a holder. The CVDD tube is held within a passage extending through the holder by filling the volume between walls of the CVDD tube and walls of the passage with a polymer, ideally an adhesive, or with a low-melting point metal or alloy, which support and hold the CVDD tube in position without exerting significant stress on it. A longitudinal axis of a through bore of the CVDD tube coincides with a centerline of the holder to allow precise location and alignment of an abrasive waterjet emitted from the CVDD tube. The CVDD tube has a rough, faceted outer surface and may have a variable wall thickness. The holder may comprise the body of the cutting head.
