Method for producing a, at least one metal material having spatial form, as well as spatial form

摘要

The method comprises the following steps: rolling the material to form a wall (1) and forming the wall (1) to form a multi-dimensional wall (3). A further step comprises welding regions (4) of the wall (3) together to form a body structure (5) of the device (2) and calibrating the body structure (5). Calibrating impanding and / or calibrating expansion produces elastic press fits , Slightly larger separation structures are pressed into the fitting seats. By pressing a nestling of the parts together, creating a process-safe weld geometry is generated. The welding takes place in the axial direction between the separating structure and the inner wall surface of the wall (3). The welding process is tuned so that it only marginally affects the work hardening of the wall and the separation structure.
