81 WELDERS, CUTTERS, AND RELATED OCCUPATIONS
This division includes occupations primarily concerned with joining, surfacing, or otherwise
fabricating or repairing structures or parts of metal or other weldable material, such as plastic or
glass, applying the following welding or cutting processes: arc; gas; resistance; solid state
(friction, ultrasonic, cold, explosion, diffusion); and other processes, such as electroslag,
electron beam, induction, thermit, and laser beam. Welders in this division are distinguished from
workers using welding equipment in other divisions by their knowledge of and experience in welding
technology and in being primarily concerned with the equipment and technology of welding. Workers
classified in other divisions may use welding equipment, but their knowledge and experience are
primarily in assembly or repair techniques. For example, welders who work on storage batteries can
be found in Group 727.
