Latest AWS CWI Part B Exam Pattern:

Here’s the latest AWS CWI Part B exam pattern, based on official AWS details and insights from recent exam takers:

CWI Part B – Practical Exam Overview

Feature Details
Number of Questions 46 multiple-choice questions (American Welding Society, Scribd)
Duration 120 minutes (2 hours) (Scribd, Welding Certification)
Format Paper-based, hands-on inspection using plastic replicas and tools (American Welding Society, Scribd)
Passing Score 72% (accurate answers not publicly detailed, but aligned with AWS standards) (Welding Certification, Scribd)

Content Breakdown

As per experienced candidates, the practical questions are distributed roughly as follows (Eng-Tips):

  • Procedure & Welder Qualifications – ~30%
  • Welding Inspection & Flaws – ~36%
  • Mechanical Tests & Properties – ~10%
  • NDT Methods – ~10%
  • Specification & Drawing Use – ~10%

This mirrors the AWS emphasis on combining inspection tools, visual inspection, code interpretation, and documentation use.

What to Expect on Exam Day

  • You’ll be given a Book of Specifications and a Book of Exhibits, plus assorted plastic replica weld samples (fillets, grooves, pipes, bends) and measuring gauges like Bridge-Cam, V-WAC, and fillet gauge (Scribd, Eng-Tips, Sitecore Content Hub, American Welding Society, American Welding Society).
  • Questions typically involve:
    • Measurements: leg size, throat, reinforcement, undercut, concavity/convexity.
    • Visual flaw detection: cracks, porosity, overlap, incomplete fusion.
    • Specification/compliance checks: using BoS tables and WPS/PQR data.
    • Code-based questions: based on the AWS BoS and related specs in your references.

Video Walkthrough

Here’s a helpful video breaking down the practical exam structure and strategies:

Master CWI Part B: Expert Tips for Inspecting Replicas & Strategies…

Quick Prep Tips

  1. Master your tools: Practice using gauges accurately without guessing.
  2. Know the BoS inside out: Be able to locate tables for undercut, reinforcement, porosity, etc.
  3. Time management: Skip tough questions and come back—plenty of peers say they use every second (Sitecore Content Hub, American Welding Society).
  4. Focus on flaw evaluation: Over 1/3 of questions are defect-related—practice identifying types and limits.

Summary

  • 46 questions, 2 hours, 72% passing score.
  • A mix of hands-on measurement and code interpretation.
  • Ideal study strategy: tool practice, BoS navigation, and timed full mock sets.
