A method for producing a component connection, having the following steps: - making available a first metal sheet, which comprises a first material, - welding a sphere or a sphere-like element, which likewise comprises the first material, onto the first metal sheet, - making available a second metal sheet, which consists of a second material different from the first material, - producing a through-hole in the second metal sheet, characterised by the steps that - at least one edge portion (6, 6') or the entire circumambient edge of the through-hole is bent over or up towards one side of the second metal sheet, as a result of which at least one clamping-collar-type element (6, 6') is yielded, - assembling the two components (1, 5) such that the sphere protruding from the first metal sheet or the sphere-like element is introduced so far into the through-hole from that side of the second metal sheet which is remote from the at least one clamping-collar-type element (6, 6') that the sphere or the sphere-like element protrudes at least partially out of the through-hole on the side of the at least one clamping-collar-type element (6, 6'), - welding the second metal sheet to the sphere or the sphere-like element and/or to the first metal sheet by at least partially fusing the at least one clamping-collar-type element (6, 6'), so that fused second material flows into an undercut region provided between the first metal sheet and the sphere or the sphere-like element, so that a positive connection is produced between the sphere or the sphere-like element and the second metal sheet and/or the first metal sheet in addition to a material-formed bond, - the welding connects the sphere or the sphere-like element in fluid-tight manner to the second metal sheet, and - the position of the spherical or sphere-like element in space and/or relative to the first and/or the second component is detected by means of an electronic, in particular by means of an optoelectronic, measuring means in contactless manner. - making available a first metal sheet, which comprises a first material, - welding a sphere or a sphere-like element, which likewise comprises the first material, onto the first metal sheet, - making available a second metal sheet, which consists of a second material different from the first material, - producing a through-hole in the second metal sheet, - at least one edge portion (6, 6') or the entire circumambient edge of the through-hole is bent over or up towards one side of the second metal sheet, as a result of which at least one clamping-collar-type element (6, 6') is yielded, - assembling the two components (1, 5) such that the sphere protruding from the first metal sheet or the sphere-like element is introduced so far into the through-hole from that side of the second metal sheet which is remote from the at least one clamping-collar-type element (6, 6') that the sphere or the sphere-like element protrudes at least partially out of the through-hole on the side of the at least one clamping-collar-type element (6, 6'), - welding the second metal sheet to the sphere or the sphere-like element and/or to the first metal sheet by at least partially fusing the at least one clamping-collar-type element (6, 6'), so that fused second material flows into an undercut region provided between the first metal sheet and the sphere or the sphere-like element, so that a positive connection is produced between the sphere or the sphere-like element and the second metal sheet and/or the first metal sheet in addition to a material-formed bond, - the welding connects the sphere or the sphere-like element in fluid-tight manner to the second metal sheet, and - the position of the spherical or sphere-like element in space and/or relative to the first and/or the second component is detected by means of an electronic, in particular by means of an optoelectronic, measuring means in contactless manner.
