Beschreibung
Zusammenfassung:	The invention relates to a method for producing a high-pressure fuel pump (22) comprising a pump housing (52) and a pot-shaped cover element (54), wherein the pump housing (52) and the cover element (54) are connected by a peripheral weld seam. The method comprises the following steps: bringing the pump housing (52) into contact with a lower electrode (71), gripping the cover element (54) using acollet chuck (80) and contacting the cover element (54) with an electrode (72), bringing the open face of the cover element (54) into contact with the face of the pump housing (52) opposite the lowerelectrode (71), wherein the cover element (54) is centred on the face of the pump housing (52) opposite the lower electrode (71), pressing the cover element (54) onto the pump housing (52) in the direction of the lower electrode (72) and introducing an electrical current from the electrode (72) via the cover element (54) and the pump housing (52) into the lower electrode (71) such that fusing occurs at the point of contact
