Abstract

In order to satisfy the requirements of productivity and quality, the welding processes of thin sheets assemblies or Tailored Welded Blanks (TWB) have given many successful advantages in manufacturing engineering. The LASER process of welding in particular makes it possible to joint sheet steels in thickness and grade identical or different in many industrial applications (car industry, pipe lines, tubes...). Additionally, Interstitial Free (IF) steels with very low C and N contents have been successfully developed in order to perform specific or complex deep drawing operations in the automotive industry. Major developments of TWB by means of LASER welding in this area have also occurred. Certain grades of IF steel are particularly suitable for deep drawing operations due to high “r” values (Lankford ratio) [1, 2].
