Course Description

Develops knowledge and skills in the use of a variety of welding electrodes when welding complex joints in advanced positions. Prerequisites: WLD 114, WLD 151, WLD 152, and 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, layout, 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 fundamentals of SMAW and FCAW operations.
  • Interpret blueprints to accurately lay out, prepare, and assemble weld joints.
  • Weld complex joint assemblies in advanced position with a variety of electrodes to AWS D1.1 Structural Steel Welding Code.
  • Apply visual 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, and welding tests.
