- CAWI is issued by AWS and includes D1.1 structural steel as Part C, not a separate add-on.
- Three separately scored parts total 266 questions across 390 minutes of active testing time.
- Each part requires at least 60% individually - there is no averaging across parts.
- The 2026 initial fee is $1,255 for AWS members or $1,520 for nonmembers.
What CAWI Actually Is
Certified Associate Welding Inspector (CAWI) is a credential administered by the American Welding Society (AWS) for individuals entering welding inspection who do not yet meet the experience thresholds required for the full Certified Welding Inspector (CWI) credential. It is not a watered-down badge or a marketing designation - it is the complete initial CAWI examination line, built around AWS D1.1 structural steel code as the designated Part C module rather than a standalone endorsement bolted on afterward.
If you've searched other pages trying to pin down exactly what CAWI means or the meaning behind the acronym, the short version is this: it's AWS's entry point into structured, code-based welding inspection work, built on the same exam architecture as CWI but scoped for people with less field experience. For a deeper breakdown of what CAWI stands for and how it fits into the broader inspector career ladder, see our companion explainer.
Exam Structure: Parts A, B, and C
The CAWI exam line is made of three separately administered, separately scored parts - not one sitting. Understanding the logistics matters as much as understanding the content, because the parts are delivered through two different systems and in a specific recommended order.
- Part A (Fundamentals): 165 questions - 150 scored plus 15 unscored pretest items - in 135 minutes. This part is closed-book and delivered by computer through Prometric testing centers.
- Part B (Practical): 46 questions in 120 minutes. Delivered on paper at AWS-authorized sites, using supplied specifications, physical weld replicas, and hands-on inspection tools. AWS recommends taking Part B before sitting Parts A and C.
- Part C (D1.1 Code Book): 55 questions - 50 scored plus 5 pretest items - in 135 minutes, computer-based through Prometric, and open-book for code application against D1.1.
Add those together and the Exam line totals 266 questions across 390 minutes of active testing - spread over separate appointments, not a single marathon session. Passing requires at least 60% on each part independently; there is no combined or averaged score that lets a strong Part A offset a weak Part B.
Key Takeaway
Because each part is scored on its own, a candidate cannot "coast" through the weakest section. Treat Parts A, B, and C as three separate exams requiring three separate preparation plans.
For the full breakdown of exactly what score you need on each part and how AWS calculates results, see our dedicated guide on the CAWI passing score requirements.
The Three Domains in Detail
AWS publishes minimum subject allocations within each part. These aren't fixed shares of one combined exam - they're minimums within each individually scored section, which is why treating each domain as its own study track matters.
Domain 1: Part A Fundamentals
Broad welding knowledge tested closed-book, without reference material. Candidates need working recall, not lookup skills.
- Definition and Terminology (12%) and Welding Processes (12%) carry the heaviest weight
- Symbols - Welding and NDE (10%) and Weld Examination (10%) follow closely
- Smaller but still tested: Welding Performance (9%), Test Methods-NDE (8%), Heat Control & Metallurgy (6%), Welding Related Calculations (6%), Duties and Responsibilities (4%), Destructive Tests (3%), and Cutting (2%)
Domain 2: Part B Practical
A hands-on, paper-based exam using supplied specs, weld replicas, and inspection tools - this is where theory meets physical measurement and judgment.
- Welding Inspection and Flaws dominates at 34% - the single largest weighting anywhere in the exam
- Procedure and Welder Qualifications follows at 28%
- Mechanical Test and Properties, NDE, and Utilization of Specification and Drawings each carry 8%
Domain 3: Part C Code Book
Open-book application of AWS D1.1, testing whether you can navigate the code under time pressure rather than memorize it outright.
- Qualification, Fabrication, and Inspection are each weighted at 25%
- Reports and Records and Materials and Design each carry 5%
- Success depends on tab organization and navigation speed as much as raw code knowledge
Note that AWS B5.1:2025 has updated some Part A terminology, combining welding and cutting content under a "Joining and Cutting Processes" heading with a recommended minimum of 14% - a shift worth tracking if your prep materials reference older subject names. For a section-by-section walkthrough of every topic inside each domain, our complete guide to all 3 CAWI content areas goes further than this overview.
| Part | Question Count | Time | Format |
|---|---|---|---|
| Part A - Fundamentals | 165 (150 scored) | 135 minutes | Closed-book, computer-based (Prometric) |
| Part B - Practical | 46 | 120 minutes | Paper-based, hands-on tools/replicas |
| Part C - D1.1 Code Book | 55 (50 scored) | 135 minutes | Open-book, computer-based (Prometric) |
Who Can Apply: Eligibility Routes
CAWI eligibility is built around combinations of education and welding-related experience, giving candidates several paths depending on their background:
- High school diploma plus 2 years of qualifying experience
- Eighth grade education plus 4 years of qualifying experience
- Less than eighth grade plus 6 years of qualifying experience
- Eighth grade plus 1 year of vocational welding training plus 3 years of experience
- 2 years of qualifying postsecondary study plus 6 months of experience
Applicants must document education, employment history, and a recent vision examination. Formal initial preparation training is not mandatory under any route, though most candidates still use structured prep to manage the breadth of Part A and the code navigation demands of Part C. For the full documentation checklist and route-by-route detail, see our dedicated CAWI eligibility and requirements guide.
Cost and Registration Mechanics
The 2026 initial CAWI fee is $1,255 for AWS members or $1,520 for nonmembers. Both figures include $120 in Part A/C seat fees, and the nonmember price bundles in 3 years of AWS Individual Membership - worth factoring in before assuming membership is a separate upsell.
When choosing your Part C reference material, make sure the codebook you study from matches your appointment's stated edition - AWS currently permits both D1.1:2020 and D1.1:2025, with both available digitally through the Exam References and Editions Guide. Printed bound references are allowed, but digital word search is disabled, so familiarity with the physical layout of your chosen edition is essential. For the complete fee breakdown, membership math, and hidden costs like retake fees, see our full CAWI cost breakdown. General registration logistics and scheduling windows are covered in our CAWI exam dates and scheduling guide.
Who Hires CAWI Holders
CAWI is designed as a supervised, entry-tier inspection credential - holders work under the direction of a CWI or SCWI rather than independently signing off inspection reports. This makes it attractive to fabrication shops, structural steel contractors, and inspection agencies that want to bring in inspection-track talent without requiring years of prior field experience up front. Employers in these settings typically pair a CAWI holder with a senior inspector on D1.1 structural jobs, using the credential as a documented, exam-verified stepping stone toward independent CWI responsibility.
Because the credential is time-limited and supervision-dependent, it's most valuable to candidates who are already working in or adjacent to a welding fabrication environment. For a realistic look at where the role fits in the market and how employers use it, see our CAWI jobs overview and our broader analysis of whether the credential is worth pursuing given the investment.
Credential Duration and the Path to CWI
CAWI status is intentionally temporary: it lasts no more than 3 years, cannot be renewed, and cannot be recertified. There is no indefinite-hold option - the clock is a hard boundary, not a renewal reminder.
During that window, CAWI holders must work under CWI or SCWI supervision. Upgrading to full CWI status isn't automatic and isn't simply a matter of waiting out the 3-year period - it requires meeting the applicable CWI experience and examination criteria on their own merits. Candidates who let the window lapse without qualifying for CWI lose the credential outright, with no grace period or extension mechanism described in the certification scope.
Key Takeaway
Plan your CWI upgrade path from day one of holding CAWI. The 3-year window is fixed and non-renewable, so treat it as an active countdown rather than a passive credential to maintain.
Building a CAWI-Specific Prep Plan
Because Parts A, B, and C are graded independently and delivered through different systems, a generic "study a little every day" approach undersells how differently each part needs to be prepared. Part A rewards memorized recall since it's closed-book; Part B rewards physical measurement practice with real tools and replicas; Part C rewards fast, accurate code navigation since it's open-book but time-boxed.
Part A Fundamentals
- Build recall of terminology, welding processes, and symbols since this section is closed-book
- Drill Weld Examination and Test Methods-NDE questions, the next-largest weighted areas
Part B Practical
- Practice hands-on measurement and flaw identification, since Welding Inspection and Flaws alone carries 34%
- Work through Procedure and Welder Qualifications scenarios using sample specs
Part C Code Navigation
- Tab and index your D1.1 edition - confirm it matches your appointment's required edition
- Time yourself answering Qualification, Fabrication, and Inspection questions under open-book conditions

Frequently Asked Questions
CAWI uses the same three-part structure (A, B, C) and the same D1.1-based Part C as the CWI exam line, but it's scoped for candidates who don't yet meet CWI's experience requirements. It results in a supervised, time-limited credential rather than the independent CWI designation.
No. Parts A, B, and C are administered separately - Part B at AWS-authorized sites on paper, Parts A and C via Prometric computer-based testing. AWS recommends taking Part B first, but they are scheduled as distinct appointments, not one combined session.
Each part requires at least 60% independently, and there is no averaging across parts. A failed part must be retaken and passed on its own before the full credential is granted.
No. CAWI status lasts no more than 3 years and cannot be renewed or recertified. Progressing beyond that window requires qualifying for CWI through its own experience and examination criteria.
AWS currently permits both D1.1:2020 and D1.1:2025 for the Part C code exam, both available digitally through the Exam References and Editions Guide. Confirm which edition your specific appointment requires and study that exact version, since digital word search is disabled and layout familiarity matters.
