Course Description

Provides an opportunity to practice using the downhill SMAW process to weld pipes in the basic position (2G) for pipe certification. Prerequisites: Department permission required. 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, safety and environmental awareness, communication, and computations.

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 basic fundamentals of SMAW E6010 operations.
  • Interpret blueprints to accurately lay out, prepare, and assemble weld joints.
  • Understand and apply basic fundamentals 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.
