Influence Principles of Linear-Weld-Line Tailor-Weld Blanks’ Formability with Different Thickness of Base Metals

Abstract:

Discussing the influence between the linear-weld-line TWBs’ different thickness of base metal and the formability of sheet by Dynaform FEM simulations technology and Dome test. Meanwhile, the correlation with the difference thickness of base metal and the limit doming height, weld-line movement are proposed, we find that both sides of the TWBs’ thickness have a great influence on the forming process. Then, the mathematical expressions are proposed between the changing thickness of base metal and limiting dome height, weld-line movement by using the genetic algorithm to fit the simulations’ data, which provide an evidence for production in theory.
