Abstract: 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.

Abstract: 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.
