Abstract Scope |
Emerging process limits for sheet metal forming of tailored blanks are determined by the mechanical properties of semi-finished sheet metals to be joined and the type of the weld seam. The weld seam properties in turn depend on the welding tool material and utilized process parameters. In this study, tailored blanks were produced made of aluminum AA6016 (2mm) and the steel grade DX54 (1mm) as well as from AA6016 (2mm) and HX380 (1mm) using different welding tool materials such as steel and ceramics. The joint between both blanks was performed as a butt joint or combined lap-/butt-joint. The formability of such tailored blanks was investigated using a three-point bending device. Best results were obtained for tailored blanks produced with ceramic welding tools using a combined lap-/butt-joint as the required force to break the weld seam was higher compared to tailored blanks produced with steel welding tools using a butt joint. |
