Study of tailor welded blanks in USIBOR1500 for B-pillar’s car application
2008 (English)Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
Abstract [en]

This master thesis has focused on the implementation of a new high strength steel called USIBOR1500 for a car’s B-Pillar. The main task has been to investigate the laser-weldability of this steel before hot-stamping. This steel has normally a tensile strength of 600 MPa. However, after a thermal treatment as a hot stamping process, it can reach up to 1500 MPa. The study has focused on the laser welding of USIBOR1500 for the B-pillar. The method used to weld the parts between them has been tailor welding. The laboratory investigation has consisted of the realization of different analysis as micrographic studies, elastic resistance studies, metallurgic studies, tensile test analysis, etc.
