Welder Fabricators may work on projects as big as bridges or as small as bicycles, but their job is essentially the same; designing, cutting and shaping metal. A Welder Fabricator may be involved in the creation of new structures or objects or may be hired to repair existing ones. Welder Fabricators are generally part of a team of other skilled workers, however, their duties are often performed with minimal supervision so Welder Fabricators must be comfortable working independently in a factory setting.
