Laser-welded steel-aluminum hybrid transition joints using a transition joint work-hardened by induction
  • design and dimensioning of tailored blanks of hybrid construction matched for loads and materials
  • production of laser-welded hybrid joints using a transition joint work-hardened by induction
  • development goal was production of a hybrid construction with good mechanical properties:
  • high joint strengt
  • good deformability of the hybrid joint by suppressing formation of intermetallic phases
