摘要： An ignition device for an internal combustion engine and method of construction therefore includes a housing with an insulator secured therein. A center electrode is mounted within the insulator. A ground electrode extends from the housing with a portion of the ground electrode defining a spark gap across from the center electrode. The center electrode has a firing tip, wherein a resistance weld joint initially bonds the firing tip to the center electrode and a continuous bead of overlapping first weld pools formed substantially from the material of the firing tip further bonds the firing tip to the electrode. A continuous bead of overlapping second weld pools formed radially outwardly from the first weld pools forms a rounded shoulder surface extending from the first weld pools to an outer surface of the center electrode.

摘要： A noble metal tip 20 for attachment to a spark plug center electrode 36 and/or a ground electrode. Noble metal tip 20 is a generally cylindrical component that includes a firing end 40, an attachment end 42, and one or more retention features 44, 46 and 60, 62. The retention features are generally conically shaped holes or recesses formed in the side of the noble metal tip, and are designed to receive molten material during a laser attachment process. Once the molten material has solidified in the retention features, a fusion layer is formed and acts as a mechanical bond or interlock between the noble metal tip and the electrode. Methods of manufacturing and attaching the noble metal tips are also provided.

摘要： A spark plug having a ground electrode with a precious metal pad welded to the ground electrode through a series of weld steps. The precious metal pad is a Pt-based pad which is attached to a side surface of the ground electrode via an attachment process that includes a resistance tack weld to initially secure the pad in place, a coining step to flatten the pad, a second resistance weld to form a permanent weld of the pad to the ground electrode, and a laser capping weld about the exposed periphery of the pad to seal the resistance weld. The laser capping weld comprises numerous overlapping weld spots that together form an annular weld bead located at or just below the discharge surface of the pad.

摘要： An ignition device for an internal combustion engine and method of construction therefore includes a housing with an insulator secured therein. A center electrode is mounted within the insulator. A ground electrode extends from the housing with a portion of the ground electrode defining a spark gap across from the center electrode. At least a selected one of the center electrode or ground electrode has a platinum or platinum-based alloy firing tip. A resistance weld joint bonds the firing tip to the selected electrode and defines a lower surface of the firing tip that is embedded a first distance beneath an outer surface of the selected electrode. A continuous bead of overlapping laser weld pools is formed over an outer periphery of the firing tip. The overlapping weld pools extend a second distance beneath the outer surface of the selected electrode, with the second distance being greater than the first distance.
