Welding occupations offer a variety of work settings. Approximately two-thirds of welders are employed in
manufacturing plants that produce motor vehicles, ships, boilers, machinery, appliances and other metal products.
Repair shops or construction companies that build bridges, large buildings, pipelines and similar metal structures
employ most of the remaining welders. Welding machine operators work in manufacturing industries. Welders may spend
their workday inside well-ventilated and well-lit shops and/or factories, outside at a construction site or in
confined spaces, such as in an underground tunnel or a large storage tank that is being built.
