Abstract
In a method for joining a functional element with a metal sheet, with the functional element having an attachment part for attachment of a structure to the metal sheet, a cold forming process employed for the metal sheet is also used to mark the metal sheet with a sink mark by which a joining position of the metal sheet with the functional element is indicated. After the functional element is joined with the metal sheet at the joining position, the joining position is checked with respect to a position of the functional element inside of the sink mark.
