Our history started in 1939 with the U.S. Navy. Ted Nelson invented the stud welding process during shipbuilding in California to significantly speed up the production pace of shipbuilding. At that time, many aircraft carriers were being built and a lot of wooden decks had to be affixed on the steel hull. His revolutionary invention by welding from one side without drilling a hole into the metal earned him a Navy “E” citation for saving millions of man-hours.

Ever since that time, stud welding has developed much further and found its way into building construction, structural elements like bridges and industrial steel applications and lastly, into car manufacturing. Stud welding technology was introduced to Europe in 1954, where Nelson Bolzenschweiß-Technik GmbH was formed in 1967 in Germany.

In 1967, the US-American company TRW acquired the Nelson Stud Welding group and sold it to FastenTech, Inc in 2000.  Seven years later, FastenTech, Inc. itself was acquired by Doncasters Group, Ltd.  In April 2018, Doncasters sold the industrial section of Nelson Fasteners to Stanley Black & Decker, while retaining the Automotive Stud Welding business, which, after starting out as Nelson Automotive, now brands as IVOSTUD to demonstrate the focus on the Automotive industry and emphasize its versatile and innovative stud welding technology.
