Abstract
Nowadays, the tailor-welded blanks (TWBs) technology has been developing very rapidly in China. The quality of tailor-welded blanks becomes more and more important for the stable manufacturing of automotive panels. therefore, it’s very necessary to find out the key factors that influence the forming performance of tailor-welded blanks. This paper experimentally studies the effect of weld line direction on drawing performance. The tailor-welded blanks with the same material pair were used in the experiment, in which the weld line is straight and forms a certain angle with drawing force. The drawing tests were done with the different angles and values of relative position. The results show that the forming performance is related to the relative position of weld line and the angle between weld line and drawing force.
