Preparation Course for the AWS Certified Welding Inspector (CWI) examination

If you are working in the business field of steel construction with your company manufacturing goods for the US-American or Asian markets , you are required to fabricate according to the rules of the AWS Codebook D1.1. A central figure in this set standard is the CWI who ensures the quality of manufacture by compulsory assignments.

Course contents

The main topics of the course are welding processes, destructive and non-destructive tests, metallurgy and the Codebook D1.1.
