Don DeCorte spent 46 years in resistance welding, including 31 at Roman Manufacturing, and now teaches the AWS Certified Resistance Welding Technician (CRWT) certification through his consulting company DTS Technical Services. He sits down with Jason to pull the curtain back on the welding process most arc guys never think about — but interact with constantly. From the 1,300+ resistance-welded products hiding inside your local Home Depot, to the flash welds on every commercial jet's front landing gear, to the butt-welded steel wheels under every 18-wheeler and state trooper car, Don makes the case that resistance welding is everywhere — you just can't see it. We cover the four core processes (spot, seam, projection, upset), the physics behind Force, Current, and Time, why aluminum welding took off thanks to chromate treatments and Elon Musk, the codes and standards that govern it (C1.1, D8, D17.2, J1, J6), and what it takes to earn your CRWT. Don also shares the story of how an $8 roast beef dinner in Detroit in 1980 turned into a lifetime with AWS — and a friendship with Amos Winsan that changed his career.
