An electrode for a spark plug includes an electrode base material and a noble metal element, the noble metal element being fastened to the electrode base material using a welding connection. The welding connection has a maximum extension perpendicular to an area of the electrode at which the noble metal element is fastened, and the welding connection has a maximum width at the area. A ratio of the maximum extension to the maximum width is greater than, or equal to 3.

Electrode for a spark plug and method for its production

An electrochemical cell including a folded electrode layer and a folded separator, a battery including the electrochemical cell, and methods of forming the electrochemical cell and battery are disclosed. The electrode layer is folded in a first direction and the separator is folded in a second direction, such that the first direction and second direction are orthogonal each other.

The invention relates to a method for positioning two components to be joined to each other along a common joint line. According to the invention, the two components are connected to each other by limited-length tack welds firmly connecting the two components, particularly by way of bonding, to each other. In order to obtain reliable and robust positioning of the components for tacking during the joining process, without requiring extensive production apparatuses, such as is required for the high-precision setting of the focal point of the welding laser relative to the joint line, the tack welds are designed such that they cross the joint line.
