A high-pressure fuel pump includes a housing, at least one piston, and a sealing device. The device is positioned on the piston so as to surround the piston, and includes a seal carrier. The carrier is connected, at least in sections, to the housing, and includes at least one radially peripheral portion that is materially bonded to the housing via a capacitor discharge weld connection. Such a pump enables improved cycle times and reduced error rates during production.

A method for resistance welding a first component to a second component including inserting the second component, at least by a connecting region, into an opening of the first component by a insertion distance and welding the first component to the second component in the process. An internal dimension of the opening and an external dimension of the connecting region are configured similar to a press fit with each other. The insertion distance is limited by an adjustable external distance limiter. A device is configured for resistance welding the first component to the second component.
