AWS D1.1 clause structure, normative references, scope limitations, and efficient code navigation strategies for the open-book exam.
Navigating AWS D1.1
The AWS CWI Part C exam is an open-book test using the current edition of AWS D1.1 Structural Welding Code — Steel. Speed and accuracy in locating requirements is critical. The exam is not a memorization test — it is a navigation test. Candidates who have built a working index of key clauses consistently outperform those who try to read the code cold during the exam.
