Course Description: This course instructs on the qualifications and knowledge requirements of a Certified Welding Inspector (CWI). Methods of testing, various procedures, and techniques of inspection. familiarize students with the basic concepts of destructive and nondestructive evaluation processes. Emphasis of record keeping methods used by the American Welding Society (AWS), American Society of Mechanical Engineers (ASME), American Petroleum Institute (API), and American National Standards Institute (ANSI).
Objectives
Upon successful completion of this course, the student should be able to:
- Apply testing symbols to weldments according to various welding standards.
- Apply codes to weldments that are currently used in the welding industry.
- Describe the role of a CWI in fabrication and the qualification of a welder.
