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.

In this episode, we dive into the story of Motobilt with Dan DuBose and Hunter DuBose. Founded in 2012 by Dan, who began fabricating parts out of necessity when he couldn’t find what he needed.
