Course Description

Provides an opportunity to practice using the downhill SMAW process to weld pipes in the advanced positions (5G and 6G) for pipe certification. Audit available.

Addendum to Course Description

This is a 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 should 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 advanced principles of SMAW E6010 operations.
  • Interpret blueprints to accurately lay out, prepare, and assemble weld joints.
  • Understand and apply advanced techniques of SMAW E6010 for downhill pipe welding operations.
  • Apply visual examination principles and practices in accordance with API 1104.

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.
