AWS CWI 9-Yr Recert study plan

AWS CWI 9-Yr Recert · Give each week a clear focus.

8 weeks · About 7 hours per week

Week 1

Nondestructive Examination Coordination Endorsement & Welding Coordination and QA Endorsement

  • Map every clause in the two 10%-weight coordination domains to a one-line recall cue, so the highest-value material is studied first

  • Draft a coordination workflow checklist covering NDE method sequencing, hold points, and reporting chain between inspector, coordinator, and QA

  • Explain aloud, without notes, how a weld inspection plan is built from drawing requirements through acceptance criteria and final documentation

  • Identify the five most common causes of coordination failure (missed hold points, wrong method, wrong timing, calibration lapse, incomplete records) and write a corrective action for each

Your checkpoint

A one-page coordination checklist plus a 20-term glossary covering both 10% domains, self-scored at 80% or better on a closed-book recall quiz

Week 2

Nondestructive Examination Coordination Endorsement & Welding Coordination and QA Endorsement

  • Sequence a full NDE program for a multi-pass groove weld from root to final acceptance, naming method, timing, and required surface condition at each step

  • Compare personnel qualification routes across the endorsements and state which certification level may perform and which may approve

  • Build a calibration and equipment-verification log template with intervals, tolerance checks, and sign-off fields

  • Write three nonconformance scenarios and the disposition path each would follow under a quality program

Your checkpoint

A completed NDE sequencing worksheet for two weld configurations plus a filled-in sample calibration log with all fields exercised

Week 3

Magnetic Particle Testing Endorsement & Penetrant Testing (PT) Endorsement

  • Describe the magnetization and penetrant application techniques, and match each to the defect orientation and surface condition it best reveals

  • Calculate the effective current or field requirement for a given part geometry and explain how part shape changes the needed technique

  • List the steps of each method in order and identify where an error causes a false indication or a missed defect

  • Interpret typical acceptance criteria language and decide accept, reject, or re-inspect for six written indication descriptions

Your checkpoint

A method-selection decision table covering both surface methods, plus six written indication calls scored against the acceptance criteria with reasoning recorded

Week 4

Structural Steel (D1.1) Endorsement & Bridge Welding (D1.5) Endorsement

  • Trace the structural steel code path from joint classification through procedure qualification, welder qualification, fabrication tolerances, and inspection acceptance

  • Compare the bridge welding endorsement against general structural steel, listing where requirements are stricter and why

  • Classify ten written joint descriptions by type, position, and required qualification test

  • Explain the difference between procedure qualification and performance qualification using a worked example for each

Your checkpoint

A side-by-side comparison chart of the structural steel and bridge endorsements with at least 12 requirement rows and a written note on each difference

Week 5

Structural Aluminum (D1.2) Endorsement & Railroad (D15.1) Endorsement

  • Explain how aluminum's thermal conductivity, oxide layer, and lack of color change on heating alter technique compared with steel

  • State the preweld cleaning, storage, and filler selection rules for aluminum and describe the consequence of each being ignored

  • Outline the railroad welding endorsement's qualification, inspection, and record-keeping expectations and contrast them with structural steel

  • Predict five defect types most likely in each of the two metals or applications and name the test that finds each

Your checkpoint

A defect-prediction matrix for aluminum and railroad welding with at least ten entries, each naming cause, likely location, and detection method

Week 6

Aerospace (D17.1) Endorsement & Pipeline (API 1104) Endorsement

  • Summarize the aerospace endorsement's emphasis on procedure control, cleanliness, documentation traceability, and qualification of both process and personnel

  • Outline the pipeline standard's girth weld acceptance approach, including how defect type and size drive rejection

  • Compare radiographic and ultrasonic evaluation roles in each of the two domains and state when each is preferred

  • Answer 25 mixed practice questions across both domains and categorize every miss by root cause

Your checkpoint

A root-cause log of every missed practice question with the corrected fact written out, plus a one-page summary of the two domains' governing philosophies

Week 7

ASME BPVC Section IX (B31.1) (B31.3) Endorsement & ISO Standard Endorsement

  • Distinguish how the ASME code and the ISO standard each assign responsibility for procedure qualification, and identify the records each requires

  • Map the pressure piping scope differences between the power and process piping sections to their inspection implications

  • Compare ISO qualification and acceptance concepts against the ASME approach using a two-column analysis

  • Resolve six written scenario questions where the applicable code changes the accept or reject outcome

Your checkpoint

A code-comparison matrix covering ASME and ISO on qualification, essential variables, acceptance, and documentation, validated by correctly resolving all six scenarios

Week 8

Structural Steel (D1.1) Endorsement & Bridge Welding (D1.5) Endorsement & Nondestructive Examination Coordination Endorsement & Welding Coordination and QA Endorsement

  • Re-run every previously missed practice item across all twelve domains and confirm each corrected fact from memory

  • Complete two timed mixed-domain practice sets and analyze score by domain to find remaining weak areas

  • Rehearse the coordination and quality workflows end to end, narrating each decision point aloud

  • Consolidate all deliverables into a single indexed reference binder organized by domain number

Your checkpoint

A full-length timed practice exam scored by domain with every miss corrected and logged, plus a completed indexed binder covering all twelve domains

Milestones

Week 2: Score 80% or better on a closed-book quiz covering only the two 10% coordination domains, and produce a coordination checklist a colleague could follow without asking questions

Week 4: Correctly classify at least 9 of 10 written joint descriptions and explain procedure versus performance qualification with no notes

Week 6: Score 75% or better on a 25-question mixed set across aerospace and pipeline, with a written root cause for every miss

Week 8: Score 80% or better overall on a full-length timed practice exam with no domain below 70%, and confirm the indexed binder is complete
