摘要

The materials determined for production of tailor welded blanks are characterized by different mechanical properties such as strength, plasticity and stiffness or by different thicknesses. These differences of materials are utilized for optimization of final product with desired properties. The deep drawing of tailor welded blanks is characterized by nonuniform material flow, instability and negative movement of the weld line. These effects are caused by different technological properties of constituent blank sheets. In case of another anomaly of these properties fatally defects on drawn parts can be created. Considerable modifications of some technological properties of sheets used in tailor welded blanks were found at solving of problems related to their formability.
