The present invention relates to a lift-and-strike welding process. In a first step, e.g. an aluminum surfaces ( ) of a component is cleaned by striking an arc and then the element ( ) to be connected is welded on by means of at least one second voltage. Besides a lift-and-strike welding apparatus, a further lift-and-strike welding process is also provided, wherein an electric cleaning current flows between a surface ( ) of a component and an element to be welded thereon, in that the component rests on the surface ( ) and then the element ( ) is lifted off the surface ( ) up to an approximately, in terms of time, constant distance for removing a coating from the surface ( ) by means of an arc, then the current changes its polarity, wherein afterwards at least one welding current is produced and then the element ( ) is welded to the surface ( ).
