SCWI study plan
SCWI · Give each week a clear focus.
8 weeks · About 8 hours per week
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
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
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
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
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
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
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
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%
