I-CAR Just In Time: Protecting UHSS Panels When Removing Spot Welds
I-CAR · August 9, 2024
Summary
This I-CAR Just In Time article and video demonstrate techniques for protecting ultra-high-strength steel (UHSS) panels from thinning during spot weld removal. It highlights how using a belt sander correctly prevents over-grinding, which could otherwise damage the UHSS panel and force its complete replacement.
What to do on the job
Use a belt sander with the correct technique to remove spot welds without thinning or over-grinding the underlying ultra-high-strength steel (UHSS) panel.
How to use it
Use this document to justify the extra care, time, and specific techniques required when separating panels joined to UHSS. It helps defend the use of proper belt-sanding techniques over aggressive grinding to prevent costly, non-reparable damage to adjacent structural boron/UHSS components.
