In this episode of the Arc Junkies Podcast, Tim Kinnaman returns to continue our deep dive into welding history, shifting the focus to gas welding and cutting. We explore how oxy-fuel processes developed alongside early electrical advancements, why oxy-acetylene welding became the dominant method for decades, and how industrial chemistry played a critical role in shaping welding as we know it today.

The conversation traces the discovery and commercialization of oxygen and acetylene, the rise of early torch designs, and the transition from cutting to welding applications. We also discuss autogenous welding, early shipyard and aviation use, and the companies and innovators that helped scale these technologies worldwide. This episode offers valuable historical context for welders, educators, and industry professionals who want to better understand the roots of modern welding processes.
