Improved Formability Testing and Prediction Modeling for Laser-welded Blanks

May 25, 2022

Laser-welded blanks offer many advantages in automotive closures and structures, but base-material necking and cracking can be an issue.

To provide better data for FE simulation modeling, EWI has developed a “mini-dogbone” tensile test for LWB formability evaluation. Hyunok Kim, EWI Forming Center Director, describes this work in Evaluating Laser-welded Blank Formability and Predicting Potential Cracks in Stamping.
