Addendum to Course Description

This is an outcome based course utilizing a lecture/lab format.  This course includes classroom discussions, videotapes, and lab demonstrations covering technical skills. Course outcomes will include;  theoretical concepts, layout, fabrication and welding.

Intended Outcomes for the course

  • Function safely in the PCC Welding Lab.
  • Interpret blueprints to accurately lay out, prepare, assemble and weld joints to specified tolerances.
  • Demonstrate welding an open root groove joint on plates in the horizontal, vertical and over head positions; and on 6 inch schedule 80 pipe in the horizontal position. 
  • Apply visual examination principles and practices in accordance with ASME Section IX.

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 student 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 and welding tests.
