摘要： A spark plug having a multilayer firing tip that minimizes the amount of precious metal used and a method of assembling a spark plug with a multilayer firing tip. The firing tip includes a discharge end and a weld end, with the weld end being connected to a center electrode, and more specifically to a base electrode on the center electrode. The weld end has a coefficient of thermal expansion, which is not between the values for the coefficients of thermal expansion for the discharge end and the base electrode. More specifically, the weld end has a coefficient of thermal expansion which is greater than the coefficients of thermal expansion for the discharge end and base electrode. The weld end is formed from Nickel and Chromium with a limited amount of additional elements. The spark plug is assembled by providing a first elongated material formed from the material used for the discharge end and a second elongated material formed from a material used for the weld end. The two materials are then joined to form a single joined material and are severed to create a firing tip. The firing tip is welded to the center electrode of the spark plug and more specifically, the base electrode.

摘要： A spark plug is provided which ensures the reliability of a weld between a noble metal chip and a ground electrode as well as higher durability and ignitability of fuel. The ground electrode is joined to a metal shell, after which the noble metal chip is laser-welded to the ground electrode. The laser welding is achieved by emitting laser beams around an interface between the noble metal chip and the ground electrode outside a given angular range within which the metal shell will be an obstruction to the traveling of the laser beams. Specifically, the laser beams are emitted without any optical interference with the metal shell. This permits the angle between the orientation of each of the laser beams and the surface of the ground electrode to be minimized regardless of the metal shell, thus ensuring a desired depth of the fused portions in the noble metal chip.
摘要翻译：提供了一种火花塞，其确保了贵金属芯片和接地电极之间的焊接的可靠性以及燃料的更高的耐久性和可燃性。接地电极与金属壳体接合，然后将贵金属芯片激光焊接到接地电极。激光焊接是通过将激光束围绕在贵金属芯片和接地电极之间的界面上，在给定的角度范围外发射激光束，在该范围内金属壳将成为激光束的行进的障碍物。具体地说，激光束与金属壳没有任何光学干涉而发射。这允许每个激光束的取向与接地电极的表面之间的角度最小化，而不管金属壳如何，从而确保贵金属芯片中熔融部分的期望深度。

摘要： A spark plug is provided after a provisional bending process, during which the earth electrode is provisionally bent at almost 90 degrees. The earth electrode, one of both ends is joined to a housing member, has first and second end-side surfaces located mutually back to back and a tip surface connecting both end-side surfaces. A noble metal chip is mounted on the first end-side surface. A bending punch is set, which has a first pressing surface to be fitted to the second end-side surface located and a second pressing surface to be fitted to a tip surface. The bending punch is first moved so that the second pressing surface comes in contact with the tip surface of the earth electrode, and then moved so that the first pressing surface presses the second end-side surface in the axial direction of the center electrode. Accordingly, a main bending process is performed.

摘要： A method for repairing damaged valve stem assemblies includes enlarging a bore within a body of a valve stem to form an enlarged bore portion and creating a conical hole in an end of the valve stem body around the enlarged bore portion. Internal threads are created within the enlarged bore portion, and a valve stem repair extension is installed in the enlarged bore portion. The valve stem repair extension has a beveled surface that facilitates formation of a hermetic seal between the valve stem body and the valve stem repair extension. The steps of enlarging the bore and creating the conical hole may both be performed using a countersinking drill bit having a beveled cutting portion.
