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 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 course syllabus will identify the methods used to assess student progress and the criteria for assigning a course grade. The student will be assessed on his/her ability to demonstrate the development of course competencies. The methods of evaluation may include one or more of the following: oral or written examinations, quizzes, written assignments, welding tests, safe work habits and task performance.
