CWB Welding Inspector Level 2 study plan

CWB Welding Inspector Level 2 · Give each week a clear focus.

8 weeks · About 7 hours per week

Week 1

Welding fundamentals and processes & Welding metallurgy and materials behaviour

  • Explain heat input and arc energy calculations and compute values for three representative procedures

  • Describe the SMAW, GMAW, FCAW, GTAW and SAW processes including typical transfer modes and applications

  • Relate weld pool solidification to macrostructure zones (fusion zone, HAZ, unaffected base metal)

  • Identify the carbon equivalent formula and predict hardenability risk for three steel compositions

Your checkpoint

A one-page process comparison table plus three worked heat-input calculations with HAZ sketches

Week 2

Welding fundamentals and processes & Welding metallurgy and materials behaviour

  • Explain hydrogen-assisted cracking mechanisms and list four practical control measures

  • Distinguish ferrite, austenite, martensite and bainite formation conditions in carbon steels

  • Describe the effect of preheat, interpass temperature and post-weld heat treatment on properties

  • Summarize stainless steel sensitization and the purpose of stabilising elements

Your checkpoint

A 400-word written summary of cracking mechanisms with a control-measure checklist

Week 3

Inspection and non-destructive examination methods

  • Describe visual inspection requirements including lighting, access and documentation

  • Explain penetrant and magnetic particle testing principles, sensitivities and limitations

  • Outline radiographic testing image quality indicators and film interpretation basics

  • Outline ultrasonic testing beam behaviour, probe selection and indication sizing concepts

  • Select appropriate NDT methods for three given defect scenarios with justification

Your checkpoint

A method-selection matrix covering five NDT methods against six defect types with rationale notes

Week 4

Inspection and non-destructive examination methods & Welding symbols, drawings and documentation

  • Identify weld discontinuities from written descriptions and classify them as planar or volumetric

  • Interpret complete welding symbols including tail, reference line, arrow side and supplementary symbols

  • Convert three written joint descriptions into correct welding symbols

  • Explain acceptance criteria language typical of visual and volumetric examination

Your checkpoint

A closed-book 25-question self-test on symbols and NDT with a scored answer key

Week 5

Codes, standards and specifications & Welding symbols, drawings and documentation

  • Explain the structure and hierarchy of a typical welding code and how to locate a clause

  • Distinguish essential, supplementary essential and non-essential variables in procedure qualification

  • Interpret drawing notes, weld maps and inspection and test plans

  • Compare code requirements for preheat and interpass control across two standards

Your checkpoint

A traceable clause-finding exercise: five code questions answered with cited clause numbers

Week 6

Quality assurance, procedure and welder qualification & Codes, standards and specifications

  • Outline the steps of welding procedure qualification and the tests required for a procedure qualification record

  • Explain welder performance qualification ranges and essential variable changes

  • Describe quality assurance responsibilities of the inspector versus the contractor

  • Identify documentation required for traceability of materials and consumables

Your checkpoint

A drafted procedure qualification record and welder qualification record template with variable tables

Week 7

Welding fundamentals and processes & Inspection and non-destructive examination methods & Welding metallurgy and materials behaviour

  • Integrate process, metallurgy and inspection knowledge to diagnose three defect case studies

  • Explain how process selection influences defect susceptibility and inspection planning

  • Evaluate inspection frequency and sampling decisions against code intent

  • Summarize common weld failures and their root causes in a structured list

Your checkpoint

Three written case-study diagnoses of at least 250 words each linking cause, mechanism and detection

Week 8

Welding fundamentals and processes & Codes, standards and specifications & Welding symbols, drawings and documentation & Inspection and non-destructive examination methods & Welding metallurgy and materials behaviour & Quality assurance, procedure and welder qualification

  • Complete a timed 100-question mixed-domain mock examination under exam conditions
