Applications of TWB(Tailor Welded Blanks) in automobile manufacturing have been developed since 1980s for both weight reduction and cost benefits. In this study, the automobile subframe applying mash-seam welded blanks was designed to remove reinforcements that were necessary in conventional subframe. For the design of mash-seam welded subframe, the characteristics of both the conventional subframe and the mash-seam welded subframe were analysed by crash and forming analysis. With these results of analyses, the prototype of automobile subframe was produced.<br/>
