Portland Community College | Portland, Oregon

This is an outcome based course utilizing a lecture/lab format. This course includes classroom discussions, videos and lab demonstrations of technical skills.  Course outcomes will include: safety, theoretical concepts, blueprint interpretation, layout, fabrication, oxy-fuel cutting, carbon arc gouging and shielded metal arc welding.

Upon completion of the course students should be able to:

1. Function safely in a welding shop and a shipyard environment.
2. Use CAC-A equipment.
3. Use SMAW equipment.
4. Use oxy-fuel cutting equipment.
5. Use common hand tools.

This will be the first course in the Maritime Welding sequence.  Each concept will be delivered in a combination of lectures and videos followed by practical demonstrations and hands-on application in the welding lab.

The student will be assessed on their 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, written assignments, visual inspection and practical welding tests.
