Abstract:

The present paper presents different available methods to determine mechanical properties of the weld zone of tailorwelded blanks (TWB). The presented methods are based on experimental tests as well as combine experimental procedures with numerical studies. The methods include metallographic observations, uniaxial tension tests, microhardness tests, indentation tests combined with inverse numerical analysis, numerical simulation of laser welding. Mechanical properties obtained for the weld zone are necessary to establish a constitutive model for TWB forming simulation.
