How One Rejected Welder Changed the Course of WWII—and Saved 50 Million Man-Hours

Discover the unbelievable true story of Ted Nelson, an $11-a-day welder who changed the course of World War II from inside a small garage.

In 1941, Nelson invented the stud welding process—a simple ceramic flux cap and spring-loaded gun that eliminated the need for scaffolding and saved the U.S. Navy more than 50 million man-hours during the war. After being ignored and dismissed by his superiors, he quit, borrowed $95,000, and built his invention himself.

When Pearl Harbor was attacked, the same shipyards that had rejected him came back desperate to buy his welding guns. Nelson’s innovation powered the construction of 2,710 Liberty Ships and 203 submarines, earning him two Navy “E” Citations for excellence in war production.

This is the story of how one man’s persistence, vision, and refusal to give up helped fuel America’s shipbuilding miracle — and proved that sometimes, the biggest revolutions start with a single spark.
