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: theoretical concepts, layout, fabrication, welding, oxy-fuel cutting and safety. 

Upon successful completion of the course students should be able to:

• Function safely in the PCC Welding Shop.

• Apply math and science concepts to welding related process.

• Operate oxy-fuel portable and track cutting systems in accordance with industry standards.

• Interpret blueprints to accurately lay out, prepare, and assemble weld joints.

• Understand and apply fundamentals of submerged arc welding (SAW) operations.

• Weld common joint assemblies with the submerged arc welding (SAW) to AWS D1.1 Structural Steel Welding Code.

• Apply visual and destructive examination principles and practices in accordance with AWS D1.1.

Welding lec/lab courses are Open Entry and Open Exit (OE/OE) and are offered concurrently. Courses are designed to meet the needs of the students with flexible scheduling options.  Students may attend full time or part time. This is an OE/OE course which does not align with the normal academic calendar.

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, written assignments, visual inspection and welding tests.
