Sheet metal workers sometimes exclusively, or in conjunction with field installation work, will fabricate, assemble, install and repair sheet metal products and equipment, such as ducts, control boxes, drainpipes and furnace casings.
Work may involve setting up and operating fabricating machines to cut, bend and straighten sheet metal; shaping metal over anvils, blocks or forms using a hammer; operating soldering and welding equipment to join sheet metal parts; or inspecting, assembling and smoothing seams and joints of burred surfaces.
