WELDING INSPECTOR

DESCRIPTION

This course addresses all the aspects that are critical to understanding this demanding area; it contains the technical information that the personnel in this area must know to perform their jobs properly. It is designed to be of tremendous benefit for personnel working to become Certified Welding Inspectors. It is also of practical use as a fundamental course for new personnel and for use as a refresher for more experienced personnel, and it is a valuable tool that helps management understand about the responsibilities of the people they supervise. This course was developed in cooperation with the American Welding Society.
