CWE study plan
CWE · Give each week a clear focus.
8 weeks · About 7 hours per week
Part A - Fundamentals (welding safety, destructive testing, metallurgy, welding symbols, inspection principles)
Map every Part A sub-topic (safety, destructive testing, metallurgy, symbols, inspection principles) against the published exam weighting and rank them by your own weak spots
Define and memorize the safety hierarchy for welding operations: fume extraction, PPE selection, hot-work permits, confined-space entry, and cylinder handling rules
Explain the difference between fusion, penetration, and reinforcement and how each is verified visually versus destructively
Draw from memory the five basic joint types and the weld types permitted on each, labeling edge preparation terminology
Your checkpoint
A one-page handwritten Part A topic map plus a 20-term safety and joint-geometry glossary scored by self-quiz at 80% or better
Part A - Fundamentals (welding safety, destructive testing, metallurgy, welding symbols, inspection principles)
Decode all standard welding symbol elements from memory: reference line, arrow, tail, groove and fillet symbols, size, length, pitch, contour, and supplementary icons
Place symbols correctly for double-sided, all-around, field, and staggered welds on blank joint sketches
Convert ten written weld descriptions into symbols and ten symbols back into written descriptions without reference material
Identify the inspection implications of each symbol element (for example, what a tail reference to a process or spec obligates the inspector to verify)
Your checkpoint
A 20-item symbol conversion set (10 written-to-symbol, 10 symbol-to-written) graded at 90% accuracy
Part A - Fundamentals (welding safety, destructive testing, metallurgy, welding symbols, inspection principles)
Describe the heat-affected zone and explain how carbon equivalent, cooling rate, and preheat interact to control hardness and cracking
Distinguish ferrite, austenite, martensite, and pearlite by formation conditions and typical weldability consequences
Contrast common destructive tests (tensile, bend, nick-break, Charpy impact, macroetch, hardness traverse) by what each proves and what it cannot prove
Predict failure location and mode for a given test coupon based on joint design and material
Your checkpoint
A metallurgy and destructive-testing comparison table covering at least eight tests with purpose, specimen type, and acceptance-criteria logic, self-tested to 85%
Part A - Fundamentals (welding safety, destructive testing, metallurgy, welding symbols, inspection principles) & Part B - Practical (applying WPSs and PQRs, inspection tools, executing required welds)
Read a full WPS line by line and state what each essential variable controls and why changing it requires requalification
Trace how a PQR supports a WPS and identify the supporting documentation an inspector should demand before accepting a procedure
Apply visual inspection acceptance criteria to undercut, overlap, porosity, crater defects, and weld profile using a written checklist
Select and correctly use basic inspection tools (fillet weld gauge, undercut gauge, magnifier, tape, temperature-indicating crayons) and record measurements
Your checkpoint
A completed WPS/PQR cross-check exercise on two sample procedures, correctly flagging at least three deliberate essential-variable mismatches
Part B - Practical (applying WPSs and PQRs, inspection tools, executing required welds)
Execute practice welds on plate to a written WPS, holding the specified process, position, amperage range, and travel technique
Self-inspect each practice coupon against the WPS and the visual acceptance criteria, documenting every defect with location and size
Calibrate your own eye by comparing your visual calls against a more experienced evaluator or documented reference set for at least five coupons
Adjust one variable at a time (amperage, angle, travel speed) and record the resulting defect pattern to build cause-and-effect intuition
Your checkpoint
Five practice coupons with written self-inspection reports plus a defect-cause log linking each observed defect to the variable that produced it
Part B - Practical (applying WPSs and PQRs, inspection tools, executing required welds)
Demonstrate correct setup and shutdown sequence for the process you will test on, including machine settings, gas flow verification, and post-weld housekeeping
Perform a complete pre-weld inspection routine: joint fit-up, cleanliness, tack quality, and dimensional check against drawing
Practice the required test position until you can complete a coupon within the time budget without stopping to consult references
Record fit-up and process parameters for each coupon so results are reproducible
Your checkpoint
Three test-position coupons produced within the time budget, each with a completed pre-weld fit-up checklist and parameter record
Part A - Fundamentals (welding safety, destructive testing, metallurgy, welding symbols, inspection principles) & Part B - Practical (applying WPSs and PQRs, inspection tools, executing required welds)
Run a full mock practical: receive a drawing and WPS, inspect fit-up, weld, and self-evaluate, all under timed conditions
Run a full mock written section covering symbols, metallurgy, destructive testing, and inspection principles under timed conditions
Review every missed item and write a corrected explanation in your own words rather than just marking the right answer
Identify your two weakest remaining sub-topics and build a targeted drill for each
Your checkpoint
One timed mock practical plus one timed mock written section, with a scored error analysis listing root cause for every miss
Part A - Fundamentals (welding safety, destructive testing, metallurgy, welding symbols, inspection principles) & Part B - Practical (applying WPSs and PQRs, inspection tools, executing required welds)
Re-drill only your documented weak areas from week 7 until each reaches consistent accuracy
Rehearse inspection-tool use and symbol decoding in short daily sessions to hold retention
Produce two final coupons that meet acceptance criteria on self-inspection and confirm with an independent evaluator where possible
Finalize a one-page pre-exam reference sheet of essential variables, acceptance limits, and safety rules that you can reconstruct from memory
Your checkpoint
Two final coupons passing self-inspection plus a closed-book reconstruction of your one-page reference sheet at 90% accuracy
Milestones
Week 2: Score 90% or better on the 20-item welding symbol conversion set without notes, and correctly label all five joint types
Week 4: Correctly flag all three planted essential-variable mismatches in the WPS/PQR cross-check and explain each in writing
Week 6: Complete three test-position coupons within the time budget with fit-up checklists and parameter records fully filled in
Week 8: Two final coupons pass self-inspection, the one-page reference sheet is reconstructed closed-book at 90%, and week 7 weak areas show consistent accuracy
