When launching a new LWB combination, ArcelorMittal Tailored Blanks validates the robustness of its process using a quick testing procedure which confirms the dynamic behavior of the part. In this video you will discover a new procedure that uses a Charpy test to ensure that Laser Welded Blanks (LWB) remain ductile after ablation. The test confirms that the partial ablation process has eliminated aluminum in the weld and that the LWB will fulfil its energy absorption role in the event of a crash. The test is cost-effective and much faster than other methods which require a crash test of a completed part. Car manufacturers will appreciate.
