Abstract

Der Blechzuschnitt weist einen zwischen Sollbruchlinien (3, 4) verlaufenden Aufreissstreifen (2) auf. An dem der Zunge (5) des Aufreissstreifens (2) entgegengesetzten Ende des Aufreissstreifens (2), in unmittelbarer Nähe des entsprechen­ den Zuschnittrandes (7) ist ein zwischen den vorgeritzten Sollbruchlinien (3, 4) quer verlaufender Ritz (6) vorgesehen. Dadurch wird beim Zusammenschweissen eine Startöffnung gebildet, welche ein problemloses Durchreissen der homo­ genen Schweissnaht erlaubt. The sheet metal blank has one between predetermined breaking lines (3, 4) extending tear strips (2). On the tongue (5) the tear strip (2) opposite end of the Tear strip (2), in the immediate vicinity of the corresponding the cutting edge (7) is one between the pre-scored Predetermined breaking lines (3, 4) transverse scoring (6) are provided. This creates a start opening when welding together formed, which is a smooth tearing through of homo allowed weld seam allowed.
