Course Description

Develops knowledge and skills using the gas metal arc welding - pulse transfer process on common mild steel and aluminum joints 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 discussion, videos, theoretical concepts, lab demonstrations and technical skills. Course outcomes include; theoretical concepts, lay out, fabrication, 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.
  • Interpret blueprints to accurately lay out, prepare, and assemble weld joints.
  • Understand and apply fundamentals of GMAW-pulse operations.
  • Weld common joint assemblies with the GMAW-pulse to AWS D1.1 Structural Steel Welding Code visual acceptance criteria in the following joints and positions.
  • 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 task performance.
