Course Description

Provides practice for pipe certification using the SMAW process to weld pipes in all positions. Prerequisites: Department permission required. Audit available.

Addendum to Course Description

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, lay out, fabrication, welding and safety.

Intended Outcomes for the course

Upon completion of the course students should be able to:

  • Function safely in the PCC Welding Lab.
  • Interpret blueprints to accurately lay out, prepare, and assemble weld joints.
  • Demonstrate complete joint penetration welds with the E6010 and E7018 electrodes to code quality standards on pipe in the 5G and 6G positions.
  • 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 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, and welding tests.
