Course Description

Develops the artist's knowledge and skills with Oxyacetylene welding and cutting, SMAW (stick) welding, GMAW (wire) welding and TIG (gas tungsten) arc welding processes. Explores metal sculpture design and construction with supporting demonstrations, slides, lectures and films. Completion of ART 293 strongly recommended. No prior welding experience is required. Audit available.

Addendum to Course Description

This is an outcome-based course utilizing a lecture/lab format. This course includes classroom discussions, video tapes, and lab demonstrations covering technical skills. Course outcomes will include the following:  theoretical concepts, layout, fabrication, welding,  oxy-fuel cutting and safety.  Historical and contemporary imagery and process will be introduced through slide/lecture presentations, films, sketchbook and research assignments will support the three-dimensional projects.  Three projects completed during the term will address sculptural form.  Projects will be concluded with a class critique/review process.Due to the substantive lecture/discussion, research and homework components of this course, it will meet the General Education Policy requirements.
