Formability of Tailored Welded Blanks in Single Point Incremental Forming Process

Abstract

This paper is focused on single point incremental forming (SPIF) of a tailored welded blanks (TWBs) that produced by laser welding process. The SPIF process is a new dieless forming technology, which is a fast and economic solution to prototyping a metal sheet product. In the past, the SPIF researches carried out with the homogeneous metal sheet blank, but now a day, the demand of TWBs is still increased especially for an automotive industry. The aim of this research is to study the formability on the weld line of laser welding TWBs (SUS 304 and St 37) by the SPIF process.
