Abstract: The quality of a weld in the tailor welded blank is very important for the success of the forming operation. The mechanical properties of the weld metal can be determined by applying different methods, such as: parallel test, normal test, microhardness test etc. The present paper investigates the mechanical properties of the weld metal in a tailor welded sheet made by joining similar metals. The investigation was performed by applying the microhardness and parallel tests in conjunction with the rule of mixture. The analysis of the behaviour of tailor welded blanks by examining the strain variation during tensile parallel test of tailor welded sheets applying the image analysis method is also presented in the paper.
