CWI Codebook Navigation and Application 2 — Questions and Answers
Question 1: In AWS D1.1, which section contains the prequalified joint detail tables for complete joint penetration groove welds?
- Section 4 (Correct answer)
- Section 5
- Section 6
- Section 7
Correct answer: Section 4
Section 4 of AWS D1.1 covers prequalified WPS requirements including the joint detail tables for CJP groove welds.
Question 2: When AWS D1.1 lists a requirement as 'shall,' this indicates the requirement is:
- Recommended but optional
- Mandatory (Correct answer)
- Advisory only
- Applicable only when specified by the engineer
Correct answer: Mandatory
In AWS codes, 'shall' denotes a mandatory requirement, whereas 'should' denotes a recommendation.
Question 3: Which AWS D1.1 table is used to determine the minimum preheat and interpass temperature for a given base metal and thickness?
- Table 4.2
- Table 4.5 (Correct answer)
- Table 6.1
- Table 3.1
Correct answer: Table 4.5
Table 4.5 in AWS D1.1 provides minimum preheat and interpass temperature requirements based on base metal category and thickness.
Question 4: A CWI needs to verify fillet weld size acceptance criteria. In AWS D1.1, where would this information be found?
- Section 4 — Prequalification
- Section 5 — Qualification
- Section 6 — Inspection (Correct answer)
- Section 2 — Design
Correct answer: Section 6 — Inspection
Section 6 (Inspection) contains the visual inspection acceptance criteria including fillet weld size tolerances.
Question 5: In AWS D1.1, Annex A is normative. What does 'normative' mean for an annex?
- It is for reference only and not mandatory
- It is mandatory and part of the code requirements (Correct answer)
- It applies only to new construction
- It supersedes all other code sections
Correct answer: It is mandatory and part of the code requirements
A normative annex contains mandatory requirements just like the main body of the code, unlike informative annexes which are for guidance only.
Question 6: Which symbol in AWS D1.1 figures indicates that a dimension or variable is the same as shown in a referenced figure?
- An asterisk (*)
- A dagger (†)
- A double arrow (↔)
- A circle with a letter (Correct answer)
Correct answer: A circle with a letter
AWS D1.1 uses circled letters (callouts) to cross-reference dimensions between figures and corresponding tables.
Question 7: When performing a code search for the maximum allowable undercut in a statically loaded tension member per AWS D1.1, which section should the inspector consult first?
- Section 4 — Prequalification
- Section 5 — Qualification
- Section 6 — Inspection (Correct answer)
- Section 8 — Strengthening
Correct answer: Section 6 — Inspection
Weld discontinuity acceptance criteria, including undercut limits, are located in Section 6 under visual inspection requirements.
