Addendum to Course Description
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.
Intended Outcomes for the course
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.
Course Activities and Design
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.
Outcome Assessment Strategies
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.
