Applying science to abrasives for better welder productivity

In this episode of The Fabricator Podcast, guest host Nate Bowman (aka Weld Scientist) joins us as we speak with 3M abrasives application engineers Matt King and Kaeleigh Wilkins about the everyday realities of grinding, from why welders depend on it to how newer abrasive technology is improving weld prep and finishing. They also discuss surface-prep tools that remove coatings without damaging the base metal and why shops may want to rethink the abrasives they’ve used for years. We also touch on the third season of Clash of the Grinders, the student competition that’s helping bring new welders into the trade. Nate also talks about his involvement with SparkForce manufacturing camps. This episode was recorded at FABTECH 2025 in Chicago.
