Determination of Weld Line Characteristics in Tailored Blanks 2000-01-2661
The use of tailored blanks by the automotive industry is a fact. New applications that use tailored blanks and improvements on existing uses are continuously being created. In order to get the most out of all the advantages of tailored blanks in the quickest and most cost effective manner an understanding of the weld and its behaviour under forming conditions is required. The purpose of this paper is to review existing formability tests for tailored blanks and to summarize current research at Queen's University toward the development of the methods that focus on the characteristics of the weld line.
