Blueprint Reading for Welders and Fabricators

DRF 122

Course Description

Prerequisite: DRF 120 or DRF 121 or SKDR 101 or WELD 120 or basic knowledge of blueprint reading. Applies principles specifically designed for welders and fabricators working with welding drawings. Interprets basic blueprint information, orthographic projection, assembly drawings, and geometric tolerancing. Places emphasis on welding symbols and welding drawings. Credit may be earned in DRF 122 or WELD 122 but not both. (30-0)
