2-Week Preparation for AWS-CWI Examination
The American Welding Society Certified Welding Inspector certification is becoming increasingly important and growing in demand. Companies and educational institutions require certification of their welding inspectors and welding educators to comply with projects, contracts, and employment qualifications. The AWS-CWI Exam is a challenging three-part exam designed to evaluate your fundamental knowledge of welding and related principles, your practical application of specifications and inspection skills, and your ability to navigate, interpret, and apply codes and specifications accurately.
This two-week exam prep course will equip you with the knowledge and skills necessary for all three parts of the AWS-CWI Exam. The three-part exam includes some of the objectives listed below:
Our course is continuously updated to ensure that the content aligns with the relevant content areas, testing domains, and literature referenced in the AWS Examination Guides for Parts A, B, C, and AWS B5.1.
