A method for producing a high-pressure fuel pump includes bringing a pump housing into contact with a lower electrode, gripping a pot-shaped cover element using a collet chuck, contacting the cover element with an electrode, bringing the open face of the cover element into contact with the face of the pump housing opposite the lower electrode, centering the cover element on the face of the pump housing opposite the lower electrode, pressing the cover element onto the pump housing in the direction of the lower electrode, and introducing an electrical current from the electrode via the cover element and the pump housing into the lower electrode, such that fusing occurs at the point of contact between the cover element and the pump housing, and such that subsequently the cover element is bonded to the pump housing. The pump housing and the cover element are connected by a peripheral weld seam.

Method for producing a high-pressure fuel pump

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.
