Portland Community College | Portland, Oregon

This is a outcome based course utilizing a lecture/lab format. This course includes classroom discussions, computer based instruction, and lab demonstrations covering technical skills. Course outcomes will include: theoretical concepts, layout, fabrication, welding, oxyfuel cutting, safety and environmental awareness, communication, computations and human relations.

·Function safely in a welding shop environment.
· Demonstrate professional work ethics.
· Apply math and science concepts to the welding related process.
· Operate oxyfuel portable and track cutting systems in accordance with industry standards
· Interpret drawing and symbols to accurately layout a project; prepare and assemble to specified tolerances; and weld joints in accordance to AWS D1.1, Structural Steel Code.
· Weld common joint configurations with the E6011electrode to code quality standards in the flat, horizontal, and vertical positions.
 

The student will be assessed on his/her ability to demonstrate the development of course outcomes. The methods of assessment may include one or more of the following: oral or written examinations, quizzes, observation, written assignments, visual inspection techniques, welding tests, safe work habits, task performance and work relations.
