Beschreibung
Zusammenfassung:	A metal band feedstock for producing contact pieces, the metal band forming a contact profile composed of a backing of hard solder material and of at least one contact layer that is applied onto the backing by electroplating. A contact profile that can be directly welded onto the contact carrier without special welding aids being required is thus produced with optimally few layers. The welding of a contact piece having the profile structure of the invention can be accomplished with a laser beam that is directed onto the hard solder backing of the contact piece through the contact carrier proceeding from the back side.
