Course Description

Covers gas metal arc welding pulse (GMAW-P) techniques to produce code-quality welds. Introduces weld testing and the use of inspection hand tools. Prerequisites: WLD 197 or department permission.

Intended Outcomes for the course

Upon successful completion of the course students should be able to:

  1. Function safely in a welding shop and a shipyard environment.
  2. Produce code-quality welds using the GMAW-P process in all positions.
  3. Assess weld quality through the application of visual examination principles and practices in accordance with industry-standard codes.
  4. Use hand inspection tools to determine code compliance.

Aspirational Goals

Each concept will be delivered via a combination of lectures and videos followed by practical demonstrations and hands-on application in the welding lab.

Course Activities and Design

Oral or written examinations, quizzes, written assignments, visual inspection, welding tests and task performance
