CWI Part C — API 1104

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 1104 habits

   API 1104 is compact and organised unlike D1.1. Candidates who search it with D1.1 habits burn the clock.

   • How 1104 is organised, in inspector language
   • Scope: pipelines and related facilities, not buildings
   • Definitions that change a lookup
   • Figures and the note under the figure
   • Tabbing a short code so you do not over-tab
   • When 1104 sends you to a referenced document
   • Edition discipline on exam day
   • Practice: four lookups in four minutes
   • Unit review: Document organisation and 1104 habits

2. Procedure qualification lookups

   The procedure qualification path in 1104, essential variables, and the test that actually qualifies the procedure.

   • What a procedure qualification proves here
   • Essential variables as a lookup
   • Test joints, positions and the coupon that has to exist
   • Destructive tests named by the code
   • Nondestructive testing of qualification welds
   • Changes that force requalification
   • Records the inspector can ask to see
   • Practice: ten procedure-qualification lookups
   • Unit review: Procedure qualification lookups

3. Welder qualification lookups

   Welder qualification is a different path from procedure qualification. Keep them from collapsing.

   • What welder qualification proves here
   • Process, position and diameter as inputs
   • Test coupons and the acceptance of those coupons
   • Period of effectiveness
   • Retesting after a failure
   • Automatic and mechanised welding as a side door
   • When a production weld cannot stand in for a qualification
   • Practice: ten welder-qualification lookups
   • Unit review: Welder qualification lookups

4. Inspection, testing and acceptance lookups

   Production inspection, NDT, and the acceptance standards that are not the D1.1 visual table.

   • Inspector responsibilities under 1104
   • Extent of visual inspection on production welds
   • NDT methods and the clauses that send you there
   • Acceptance standards: how the tables are organised
   • Repair, removal and re-inspection
   • Automatic welding inspection differences
   • Records that have to travel with the weld
   • Practice: eighteen acceptance lookups
   • Unit review: Inspection, testing and acceptance lookups

5. Special conditions and referenced paths

   The clauses people skip because they were studying D1.1 examples.

   • Design and preparation of the joint as a 1104 problem
   • Miter joints, fittings and attachments
   • In-service welding as a different neighbourhood
   • Mechanised and automatic production
   • When the company specification tightens 1104
   • Existing pipelines and the inspection you can still do
   • Safety as an inspection condition, not a slogan
   • Practice: eight special-condition lookups
   • Unit review: Special conditions and referenced paths

6. Timed drills and mixed review

   Part C on 1104 is won by people who stopped looking for D1.1 clause numbers.

   • First-pass triage for a short code
   • Items that require two figures
   • The unused wall-thickness number
   • Mixed set: essential variable, NDT and acceptance
   • Full-length timing rehearsal
   • What you do not import from D1.1
   • 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 api 1104 document organization alongside procedure, qualification, and acceptance lookups, 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.
