Coded Welder (EN ISO 9606) study plan

Coded Welder (EN ISO 9606) · Give each week a clear focus.

8 weeks · About 7 hours per week

Week 1

Essential variables and qualification ranges (process, material group, consumable, position, thickness, joint type)

  • Define each essential variable (process, material group, consumable, position, thickness, joint type) in your own words without notes

  • Map every essential variable to its qualification range using the standard's tables

  • Work through 15 practice scenarios where a change in one variable must be judged as within-range or requiring requalification

  • Build a one-page decision flowchart linking variable changes to requalification triggers

Your checkpoint

A completed essential-variable matrix (variable x qualification range x requalification trigger) plus scored answers to 15 range-judgement scenarios at 80% or better

Week 2

Essential variables and qualification ranges (process, material group, consumable, position, thickness, joint type) & Test piece preparation, dimensions and welding of the test assembly

  • Apply thickness and diameter range rules to at least 10 worked examples covering plate and pipe

  • Explain how material grouping affects qualification coverage and identify group boundaries

  • Describe test piece dimensions, preparation and joint configuration requirements for butt and fillet assemblies

  • Sequence the steps for welding a test assembly from preparation through completion, noting position constraints

Your checkpoint

A written test-piece preparation checklist covering dimensions, joint type, position and thickness, validated against 10 worked examples

Week 3

Examination and testing of test pieces (visual, radiographic, bend, macro/micro, fracture tests) & Acceptance criteria and evaluation of test results

  • List the examination and testing methods applied to test pieces and state the purpose of each

  • Distinguish what visual, radiographic, bend, macro/micro and fracture tests each reveal

  • Match each test method to the defect types it is designed to detect

  • State the acceptance criteria thresholds for each test method and apply them to sample results

Your checkpoint

A test-method-to-defect-to-acceptance-criteria reference table plus correct accept/reject decisions on 12 sample test results

Week 4

Welding processes and process designations covered (e.g. 111, 135, 141, 311) & Scope, normative references and definitions of EN ISO 9606

  • Identify the numeric process designations covered (e.g. 111, 135, 141, 311) and describe each process's key characteristics

  • Explain how changing the welding process affects qualification validity

  • Summarize the scope of the standard and identify its normative reference structure

  • Define the core terms used throughout the standard and use them correctly in written answers

Your checkpoint

A process-designation flashcard set (minimum 6 processes) plus a definitions glossary scored by self-quiz at 85% or better

Week 5

Validity, period of validity, confirmation and revalidation of qualifications & Certification, certificates and qualification test records (QTR)

  • State the period of validity of a qualification and the conditions that maintain it

  • Explain the confirmation and revalidation routes and when each applies

  • Differentiate between a certificate and a qualification test record and list the data each must contain

  • Draft a model certificate and a model QTR with all required fields populated

Your checkpoint

A completed model certificate and model QTR, cross-checked field-by-field against the standard's requirements

Week 6

Health, safety and good workshop practice during qualification testing & Test piece preparation, dimensions and welding of the test assembly

  • Identify the principal health and safety hazards during qualification testing and the controls for each

  • Describe good workshop practice for test piece handling, marking and traceability

  • Explain how test piece preparation errors can invalidate a qualification test

  • Produce a pre-welding safety and preparation sign-off list for a qualification session

Your checkpoint

A hazard-control and pre-welding sign-off checklist covering at least 10 hazards with matched controls

Week 7

Essential variables and qualification ranges (process, material group, consumable, position, thickness, joint type) & Examination and testing of test pieces (visual, radiographic, bend, macro/micro, fracture tests) & Acceptance criteria and evaluation of test results

  • Integrate essential variables, testing and acceptance criteria in full-length scenario questions

  • Complete a timed mock exam and classify every error by domain

  • Re-derive the qualification range for the three most-missed variables from the standard

  • Rewrite incorrect answers with the correct reasoning documented

Your checkpoint

A timed 60-question mock exam with a scored error log showing domain-level accuracy and a written correction for every missed item

Week 8

Scope, normative references and definitions of EN ISO 9606 & Welding processes and process designations covered (e.g. 111, 135, 141, 311) & Validity, period of validity, confirmation and revalidation of qualifications & Certification, certificates and qualification test records (QTR) & Health, safety and good workshop practice during qualification testing

  • Review all lower-weightage domains using condensed summary sheets

  • Re-test on previously missed items from the week 7 error log

  • Recite the validity, confirmation and revalidation rules from memory

  • Complete a final full mock exam under exam conditions

Your checkpoint

A final mock exam score of 85% or better with no domain below 70%, plus a one-page consolidated revision sheet
