Nelson® stud welding’s rich history began in 1939 with the U.S. Navy. Edward “Ted” Nelson® invented the stud welding process at the Mare Island shipyard in Vallejo, California, as a means to speed production of shipbuilding. The first application was to secure wood decking on submarines, but was quickly adopted and used on battleships and aircraft carriers.

His revolutionary invention earned him two Navy "E" citations for saving over 50 million man-hours. Today Nelson® stud welding products provide innovative technologies like battery-powered, portable, and lightweight equipment to develop the next generation of fastening solutions
