Jordan Smith of the Build Show and Risinger Homes paid a visit to his former employer, Arc Specialties, to get a behind-the-scenes look at some uncommon welding techniques. Smith's former boss, Dan Allford, takes us through the processes of Atomic Hydrogen Welding, Robotic Flex Core Welding (FCAW), Magnetically Impelled Arc Butt Welding (MIAB), Robotic Plasma Arc Gouging, and High-Speed Resistance Spot Welding. It's an interesting look at some sophisticated processes.
