초록

Tailored Blanks are defined as two or more separate pieces of sheet material having the same or dissimilar thickness and/or physical properties, joined together before forming. Its application is being increased especially in the automotive industrial area for the cost reduction, weight saving, and improvement of strength. In this paper, the deforming behaviour of the laser welded blanks with regard to different thicknesses and combinations are described through some experimental investigations on the formability of a door inner. To investigate how the combination of thickness and material property influences the movement of welding line, a series of laser welded T/B blanks are tested.
