CWI Part C — AWS D1.1

HoldPoint study map

Course outline

Unit and lesson titles below are HoldPoint original material. They are not an official exam bulletin.

1. Document organisation and open-book habits

   D1.1 is a map. Part C scores whether you can open the right clause family before the clock eats the item.

   • How D1.1 is organised, in inspector language
   • Scope, exclusions and the work this code does not cover
   • Normative annexes versus the clauses you start in
   • Tables, figures and the note that modifies the row
   • Tabbing scheme that survives a timed exam
   • When a clause sends you to another clause
   • Edition discipline: you work the book on the table
   • Practice: four lookups in four minutes
   • Unit review: Document organisation and open-book habits

2. Design and prequalification lookups

   Prequalified joints, matching, and the design tables you open only after you have classified the joint.

   • Prequalified versus qualified-by-test as a lookup
   • Matching filler metal to base metal without inventing a pair
   • Fillet-weld details as a figure problem
   • Groove details and the joint designation
   • Loading condition as an input, not an afterthought
   • Tubular versus non-tubular: different neighbourhoods of the book
   • When prequalification is lost
   • Practice: twelve prequalification lookups
   • Unit review: Design and prequalification lookups

3. Fabrication and erection lookups

   Fit-up, preheat, and the fabrication rules that are not inspection clauses.

   • Fit-up tolerances as a table problem
   • Preheat and interpass: the lookup order
   • Assembly, alignment and temporary welds
   • Repairs of base-metal discontinuities
   • Erection, camber and field modifications
   • Stud welding clauses as a side door
   • Existing structures: the clause family that is not new work
   • Practice: ten fabrication lookups
   • Unit review: Fabrication and erection lookups

4. Inspection and acceptance lookups

   The inspection clause family, the acceptance tables, and the NDT handoff.

   • Inspector responsibilities as written in the code
   • Extent of visual inspection
   • Acceptance tables: row first, column second
   • NDT methods and when the code sends you there
   • Engineer-approved alternatives
   • Repair, removal and re-inspection lookups
   • Contract documents that tighten the code
   • Practice: eighteen acceptance lookups
   • Unit review: Inspection and acceptance lookups

5. Qualification lookups

   Procedure and personnel qualification as open-book problems, not memorised ranges.

   • WPS qualification path in D1.1
   • Prequalified WPS limits as a table
   • Welder qualification: process, position, thickness
   • Essential variables as a lookup, not a list you recite
   • Period of effectiveness and renewal
   • Tack-welder qualification
   • When a change forces requalification
   • Practice: ten qualification lookups
   • Unit review: Qualification lookups

6. Timed drills and mixed review

   Part C is won on the second pass. First pass: easy lookups. Second pass: items that send you twice.

   • First-pass triage for a D1.1 book
   • Items that require two clauses
   • The unused dimension in the stem
   • Mixed set: preheat, acceptance and qualification
   • Full-length timing rehearsal
   • What you do not import from Part B
   • Final self-assessment
   • Handoff to the full CWI sequence
   • Unit review: Timed drills and mixed review

Who this roadmap is for

Welding professionals preparing for the CWI Part C portion or route of the AWS CWI program.

Always confirm the current AWS eligibility rules, exam outline, references, fees, and scheduling policies before purchasing materials or setting an exam date.

Study sequence

A controlled preparation roadmap

1. 01

   Verify the current program

   Start with the official source links below. Record the current outline, permitted references, eligibility rules, and any application steps that apply to your route.

2. 02

   Map the reference set

   Turn each published domain into a retrieval map. Practice where to look before trying to memorize isolated answers.

3. 03

   Build the CWI Part C core

   Study aws d1.1 document organization alongside clause, table, figure, and annex retrieval, then connect both to field decisions and documentation.

4. 04

   Practice under controlled timing

   Use short lookup drills first, then mixed review. Track missed concepts and slow retrievals separately so each can be corrected.

5. 05

   Recheck before exam day

   Return to the credentialing body for last-minute policy or reference changes. Do not rely on a third-party summary for current exam administration.
