Portland Community College | Portland, Oregon

This is an outcome based course utilizing a lecture/lab format. This course includes classroom

discussions, videotapes, and lab demonstrations of technical skills.  Course outcomes will include:

theoretical concepts, lay out, fabrication, welding, oxy-fuel cutting and safety.

Upon completion of the course students will be able to:

• Function safely in the PCC Welding Lab.
• Operate oxy-fuel portable and track cutting systems in accordance with industry standards.
• Understand and apply code requirements for FCAW E71T-8.
• Interpret blueprints to accurately lay out, prepare, and assemble weld joints.
• Weld single V-groove welds with E71T-8 to AWS D1.1 Structural Steel Welding Code.
• Operate an CAC-A (Carbon Arc Cutting - Air) system in accordance with industry standards.
• 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 welding tests and task performance.
