Forming of Tailor-Welded Blanks Through Centerline and Offset Laser Welding

The forming of low and high strength tailor welded steel sheets into preferred three-dimensional shapes by a homogeneous distribution plastic strain is highly difficult. In this work, the formability tailor-welded blanks prepared using laser welding (IS 513 CR2, IS CR3) tensile (AISI 304) were analyzed formation edge profile weld line movement was also examined. results showed decrease in characteristics owing to increase Strength Ratio. Scanning Electron Microscope analysis fracture locations within unsuccessfully formed presence tempered martensite soft zone found be most predominant factor affecting its failure. investigated tailored predicted finite element simulation compared with experimented for validation.
