SCWI study plan

SCWI · Give each week a clear focus.

8 weeks · About 8 hours per week

Week 1

Welder Performance Qualification (WPQ1)

  • Define each welder performance qualification essential variable and classify it as change-requiring-requalification or not

  • Distinguish performance qualification from procedure qualification and list what each one proves

  • Map the qualification test assembly requirements (material, thickness, joint type, position) to the range of qualification they grant

  • Describe the qualification pathway options for a welder: standard test coupon, production weld test, or documented prior qualification

Your checkpoint

A one-page essential-variable table for welder qualification with at least 20 variables classified, plus a 15-question self-quiz scored at 80% or higher

Week 2

Welder Performance Qualification (WPQ1)

  • Determine the qualified thickness and diameter ranges produced by a given test coupon and position

  • Sequence the steps of a performance qualification test from coupon preparation through destructive testing

  • Interpret the acceptance criteria applied to bend specimens and to radiographic examination of test welds

  • Explain the conditions that void or periodically renew an existing welder qualification (continuity, lapse, re-test triggers)

  • Draft a correction plan for a welder whose qualification lapsed or whose essential variable changed

Your checkpoint

A written range-of-qualification worksheet covering 5 different test-coupon scenarios with the resulting qualified ranges stated for each

Week 3

Welding Procedure Qualification (WPQ2)

  • Identify the essential and non-essential (supplementary) variables of a welding procedure specification and separate them correctly

  • Construct a procedure qualification record from a supplied set of test data, including ranges and supporting test results

  • Relate each procedure essential variable to the mechanical or metallurgical reason it is controlled

  • Explain how procedure qualification supports the ranges of thickness, position, and consumable that may be used in production

Your checkpoint

A complete draft procedure qualification record and companion welding procedure specification for one joint configuration, cross-checked against a 10-point essential-variable checklist

Week 4

Welder Performance Qualification (WPQ1) & Welding Procedure Qualification (WPQ2)

  • Compare welder qualification requirements against procedure qualification requirements side by side and state where they overlap and diverge

  • Diagnose five written scenarios in which a WPS or a welder qualification is applied outside its qualified range

  • Produce the documentary trail that links a qualified procedure to a qualified welder to a specific production weld

  • Self-assess against the two domains and rank remaining gaps by exam impact

Your checkpoint

A single integrated qualification-flow diagram plus a 40-question timed practice set on domains 1 and 2, scored at 75% or higher

Week 5

Welding Coordination and QA (WCQA)

  • Define the responsibilities of welding coordination personnel and distinguish them from the inspector's and the welder's responsibilities

  • List the documents that must be controlled in a welding quality system and describe the control method for each

  • Explain how a welding procedure is issued, revised, and withdrawn under document control

  • Identify the records that must be retained, for how long, and who owns them

Your checkpoint

A document-control register template populated with at least 12 welding-related document types, each with an owner and retention rule

Week 6

Welding Coordination and QA (WCQA)

  • Outline the audit trail from contract review through final inspection for a fabricated weldment

  • Classify nonconformities by severity and draft corrective actions for three sample nonconformity descriptions

  • Describe how subcontractors, consumable storage, and equipment calibration are controlled within the quality system

  • Explain how welder and procedure qualifications are verified before production starts

Your checkpoint

A one-page pre-production qualification readiness checklist covering procedure, welder, consumables, equipment, and documentation, with pass/fail criteria for each line

Week 7

Nondestructive Examination Coordination (NDEC)

  • Match each common nondestructive examination method to the discontinuity types it detects and its principal limitations

  • Sequence NDE timing relative to welding completion, heat treatment, and pressure testing

  • Explain the qualification and certification expectations for NDE personnel and how to verify them

  • Interpret an examination report to judge whether the indicated result is acceptable against a stated acceptance criterion

  • Describe how the welding coordinator supports NDE planning, coverage, and reporting

Your checkpoint

A method-selection matrix covering at least five NDE methods against at least eight discontinuity types, plus 10 practice report-interpretation items scored at 80% or higher

Week 8

Welder Performance Qualification (WPQ1) & Welding Procedure Qualification (WPQ2) & Welding Coordination and QA (WCQA) & Nondestructive Examination Coordination (NDEC)

  • Re-rank all four domains by practice-exam performance and re-study the two weakest areas

  • Complete two full-length timed mock exams under exam conditions

  • Recite from memory the key essential-variable differences between welder and procedure qualification

  • Build a one-page final-review sheet of formulas, ranges, and acceptance criteria you keep getting wrong

Your checkpoint

Two completed timed mock exams with scores recorded per domain and a one-page final-review sheet for any domain still below 80%

Milestones

Week 2: Explain, without notes, how a single test coupon converts into qualified thickness, diameter, and position ranges for a welder

Week 4: Score 75% or higher on the 40-question domains 1 and 2 practice set and submit the integrated qualification-flow diagram

Week 6: Produce the pre-production readiness checklist and correctly classify at least 8 of 10 sample nonconformities

Week 8: Score 80% or higher on both full-length mock exams with no domain below 70%
