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, layout, fabrication, oxy-fuel cutting, carbon arc gouging and flux cored arc welding.

Upon completion of the course students should be able to:

1. Function safely in a welding shop and a shipyard environment.
2. Demonstrate an understanding of shipyard terminology used in maritime welding.
3. Select correct materials for maritime welding projects.
4. Create a material list for a maritime welding project.
5. Fabricate complex joint assemblies.
6. Weld complex joint assemblies in all positions.

This will be the second course in the Maritime Ship Fitting 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 welding tests.
