master ICC inspector, AWS CWI

Got an 87% on the CWI part A, a little less on the CWI part B (practical). Used the AWS on-line tutorial, plus my own experience.

Where you need to find exam material is for the AWS CWI part C - they ONLY offer classes and training for the structural and for the pipeline welding codes. ASME Section IX? 31.1 and 31.3? You are on your own. No support from the AWS at all.

How do you propose documenting the self-study hours you intend to report to the AWS for taking this exam?

Beginning February 2016, the CWI exam will be substantially revised. It will now include:

A. Book of Exhibits (will not be provided to certification candidate until the exam)
B. Pipe sample to be inspected to portions (modified \ "fake")
i. ASME 31 - Standards of Pressure Piping
ii. API 1104 - Welding of Pipelines and other Related Facilities
iii. AWS D1.1 - Structural Welding Code - Steel
C. Book of Specifications reflects the above changes and has been increased in size to approximately 55 pages.

Documentation of self-study hours is not required by AWS to qualify to take the CWI exam; qualification is determined by education level, experience inspecting welds to a code(s)\standard(s), and meeting visual acuity requirements as outlined in B5.1 - Specification for the Qualification of Welding Inspectors.

Just took the CWI exam in January. All new study materials for the practical.
The new materials are now based on actual codes instead of made up ones.
Very in depth and difficult exam. They have added pipe molds to the mix, and all the molds are brand new.
