Abstract：

Comparing with monolithic,because of weld line intervention,difference in thickness and so on,the forming limit of TWBs(tailor-welded blanks) has its own traits.Previous research has shown that thickness ratio,main strain and rolling direction influences the FLD of TWBs.The most common method to establish FLD of TWBs is test.A few theory methods are used too.More attention should be paid to what are main factors and how these factors influence the FLD of TWBs.
