Abstract
On a body structure (2) for an automobile (1) having a structural component (3) made of at least high-strength steel sheet, the structural component (3) is provided with a predetermined cutting location (5, 5a, 5b, 5c) for applying a separating tool. In the method for producing the structural component (3), a steel sheet is formed and subjected to heat treatment for forming regions with high strength and reduced strength. At least one region of the structural component (3, 7, 8, 12) with reduced strength is formed as a predetermined cutting location (5, 5a, 5b, 5c) for applying a separating tool during a hot-forming process of a steel sheet in a tool or during heat treatment of the structural component (3, 7, 8, 12) following a forming process in a tool by changing the mechanical properties.
