Study on the Formability of Different Gauge Tailor Welded Blanks Based on Tensile Test

Abstract

The formability of different gauge tailor welded blanks is difference to single material blanks. As an effective and practical material property test method, tensile test were applied to study it. Base material and tailor welded blanks test specimens had been designed for tensile testing. The results of tensile test indicated that the strength difference and weld line location in the TWBs plays an important role on the formability aspect.
