Welding is an art, a trade, and a skill used by other trades. More than 75 occupational titles are listed by the U.S. Department of Labor that entail some form of welding-related activities. In DuPage County, welding ranks high on the list of the 30 fastest-growing occupations. These figures do not include more than one million people nationally who currently use welding as part of their occupation, including mechanics, machinists, plumbers and maintenance workers. Add to that the hobbyist, sculptor and other artisans, and you have a sizable number of people needing and/or desiring to learn the art of welding.
