Investigations of weld-line movements for the deep drawing process of tailor welded blanks

초록

The purpose of this study is to investigate the weld-line movement of the laser welded sheets during deep drawing process. Two kinds of blank shape, namely square and circular, have the three different initial weld-line locations, respectively. During the deep drawing process of these specimens, the differences of weld-line movement and thickness strain distribution are investigated by experiment and analysis.
