    摘要： Provided is a method of making a spark plug (100) having a noble metal chip (32) joined to an electrode main body (4m) of a ground electrode (4) by interposing therebetween an intermediate member (33). The method comprises the steps of prior to joining the noble metal chip (32) to the electrode main body (4m), joining the intermediate member (4m) and the noble metal chip (32) together, placing a noble metal chip and intermediate member assembly (34) on the electrode main body (4m) in a way as to allow the intermediate member (33) to contact the electrode main body (4m), and welding the electrode main body (4m) and the intermediate member (33) together while restricting relative movement of the electrode main body, (4m) and the intermediate member (33) without applying an urging force to a joint between the intermediate member (33) and the noble metal chip (32).

    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 man 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.
