Abstract: A method produces hollow gas exchange valves, in particular with a cooling medium introduced into the hollow valve stem. The hollow of the valve stem is preferably drilled from the valve head side and, after the introduction of the cooling medium, sealed again by surfacing. A thin filling piece is inserted to a defined depth into the drilled hole temporarily holding the weld pool of the surfacing weld. By means of surfacing, it is possible to achieve cost savings over other sealing methods. The surfacing is preferably performed by a welding method in which the workpiece is not part of an electric circuit through which the welding energy flows. Preferable methods include gas welding, electron beam welding or laser welding. With these methods, so-called edge effects can be avoided.

Abstract: A hybrid induction welded piston including an upper piston part welded to a lower piston part is provided. The piston is produced by induction heating the upper piston part and the lower piston part, and bringing the parts together to a part growth compensated position. The method then includes rotating the upper piston part 17 to 34 degrees clockwise and then 17 to 34 degrees counterclockwise. In addition to controlling the axial position and degree of rotation, the force applied to the piston parts is controlled so that preferably no flash is formed in a narrow cooling chamber of the piston. During the rotating steps, the pressure gradually increases to a maximum level which occurs while the upper piston part is rotating in the second direction. The piston includes a homogeneous metallurgical bond across the weld and no indentation on the outer surface at the weld prior to machining.

Abstract: A piston (120) and method for making a piston (120) for a fuel-injected diesel engine adapted to withstand the damaging effects of fuel injection plume-induced oxidation in the regions of the piston bowl (134) and rim (130). The surfaces of the piston crown (126) targeted by the fuel injection plume (138) are first coated with a corrosion-resistant and oxidation-resistant composition applied as a slurry or by a thermal spraying technique, such as HVOF or plasma spraying. Thereafter, a high energy industrial laser beam irradiates the as-sprayed coating to increase its density, while simultaneously reforming its microstructure so as to fuse, alloy, and materially bond the coating material with the underlying steel substrate, thereby resulting in a durable protective surface for the steel piston crown (126).

Abstract: A piston is manufactured with functional recesses (6, 7, 8) thereof formed from property improving material (18b, 18c, 18d). A blank (10) defines a mounting recess (12, 14, 16) and a quantity of said property-improving material (18b, 18c, 18d) is secured within said mounting recess. Said functional recess (6, 7, 8) is machined out of said quantity of property-improving material. The process for securing said property-improving material (18b, 18c, 18d) comprises forming a rod (20, 22, 34) from a material which on plasticisation under heat and pressure forms said property-improving material, inserting an end of the rod into said mounting recess, and rotating said rod in contact with a surface of the mounting recess (12, 14, 16), while applying force to the rod to feed it into the mounting recess. The rotational speed of said rod and the force applied thereto being controlled so that frictional heat is generated between the rod and the blank, causing plasticisation of the material of the rod, thereby, upon solidification converting it into said property-improving material (18b, 18c, 18d).

Abstract: Exemplary piston assemblies and methods of making the same are disclosed. An exemplary piston may include a piston body defining a piston axis, the piston body having a skirt and forming a lower surface of a cooling gallery. The body may include radially inner and outer body mating surfaces. The piston may further include a cooling gallery ring cooperating with the piston body to form the cooling gallery. The piston body and cooling gallery ring may be joined together along radially inner and radially outer interface regions to form a generally one-piece piston assembly. In some exemplary approaches, mating surfaces of the body and ring may be positioned adjacent a support surface configured to inhibit or prevent weld spatter formed in a process joining the ring and body from the cooling gallery.
