Welding Inspection and Quality Control



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 also of practical use as a fundamental course for new personnel and for use as a state-of-the-art refresher for more experienced personnel and it is a valuable tool that helps management understand the responsibilities of the people they supervise. It is aimed at industries where welding must be performed in compliance with strict codes and standards.
