- Eligibility is a sliding scale: an engineering bachelor's degree needs one year of welding experience; high school needs fifteen.
- Parts 1 and 2 must be passed before Parts 3 and 4, and you have one year to apply for Parts 3 and 4.
- Passing requires at least 60% on every part plus a weighted composite of at least 70%.
- CWEng is an AWS credential, not a state Professional Engineer license, and routine renewal needs no new exam.
What "Requirements" Actually Means for the CWEng
The American Welding Society (AWS) Certified Welding Engineer credential is built on two gates. The first is eligibility: your combination of education and welding-based experience must satisfy one of the approved routes. The second is examination: you must pass four separate computer-based exams delivered through Prometric testing centers. Neither gate substitutes for the other. A candidate with a doctorate still sits the exams unless AWS approves a specific exemption, and a candidate who passes every exam still needs documented experience.
If you are new to the credential itself, the overview in What Is CWEng Certification? explains what the designation represents. This article focuses narrowly on who can qualify, what you must submit, and in what order the pieces must happen.
The Five Education and Experience Pathways
AWS sets a sliding scale. The less formal engineering education you hold, the more welding-based experience you need to compensate. The approved routes are:
| Education Background | Required Welding-Based Experience |
|---|---|
| Bachelor's degree or higher in engineering | One year |
| Bachelor's degree in engineering technology | Two years |
| Bachelor's degree in another related field | Five years |
| Associate in applied science degree | Ten years |
| High school diploma or equivalent | Fifteen years |
Two practical notes follow from this table. First, "welding-based experience" is not the same as "years in a plant that happens to weld." Your documentation should show engineering-level responsibility tied to welding: procedure development, joint design, metallurgical evaluation, fabrication planning, quality or inspection oversight, or similar work. Second, the line between an engineering degree and an engineering-technology degree matters. It changes your experience requirement from one year to two, so be precise about what your transcript says.
What the Application Package Must Contain
The application is not a form you can complete in an evening from memory. AWS requires:
- Education documentation that matches the pathway you claim
- Experience documentation showing the duration and nature of your welding-based work
- Professional references who can speak to your experience
- A photograph
Start collecting references early. The most common delay for working engineers is not the exams but waiting on a former supervisor or employer to confirm dates and responsibilities. If your experience spans several employers, assemble the chronology first and then identify who can vouch for each stretch.
Exam Sequence Rules: Parts 1 and 2 Before Parts 3 and 4
The CWEng is not a single sitting. It consists of four examinations, and the dated AWS Examination User Guide imposes an order:
- Part 1 (Basic Science Fundamental Examination): 36 multiple-choice questions, two hours, closed book.
- Part 2 (Applied Science Fundamental Examination): 27 multiple-choice questions, two hours, closed book.
- Part 3 (Welding Related Disciplines Examination): 60 multiple-choice questions, three hours of answer time within a three-hour-fifteen-minute appointment, open book.
- Part 4 (Practical Welding and Related Applications Examination): 40 multiple-choice questions, two hours thirty minutes of answer time within a three-hour appointment, open book.
Parts 1 and 2 must be passed before you take Parts 3 and 4. After you pass the last of Parts 1 and 2, you have one year to apply for Parts 3 and 4. Let that window lapse and you risk having to repeat the process, so schedule the second pair with that deadline in mind rather than treating it as open-ended.
Across all four exams there are 163 questions and nine hours thirty minutes of answer time. This is not one continuous sitting, and appointment time adds to the answer time. An on-screen scientific calculator is available for all four parts.
For a closer look at the timing and scheduling side, see CWEng Exam Dates 2026: Testing Windows, Deadlines & Scheduling.
Exemption Routes: FE, PE, IIW and EWF
Some candidates hold credentials that AWS may recognize in lieu of part of the examination. These are the routes named in AWS B5.16:2006 and the related materials:
Engineering Fundamentals (FE) Route
AWS B5.16:2006 provides a route in which the Fundamentals of Engineering examination can satisfy Parts 1 and 2. That removes the two closed-book science exams but leaves Parts 3 and 4.
- AWS approval governs the exemption; it is not self-declared
- Parts 3 and 4 still apply
State Professional Engineer (PE) Route
A separate route exists for a state PE license specifically in welding engineering. The 2026 PE-exemption application fee is $480 for members and $745 for nonmembers.
- The license must be specifically in welding engineering
- AWS approval governs the outcome
IIW and EWF Diploma Holders
Holders of an IIW International Welding Engineer or EWF European Welding Engineer diploma have a diploma-plus-one-year-experience eligibility route. This is an eligibility route, not an automatic substitution for the entire CWEng examination.
- Do not assume the diploma waives all four exams
- Request AWS's written determination on your specific record
One clarification worth repeating: the CWEng itself is not a state Professional Engineer license. It is an AWS professional certification. Holding a PE can create an exemption route, but earning the CWEng does not make you a licensed PE.
Score Requirements and the Weighted Composite
Qualification is not complete when you merely sit the exams. You must clear two thresholds at once: at least 60% on each part and a weighted composite of at least 70%. Under AWS B5.16:2006, as referenced by the dated exam guide, the composite is:
Composite = 0.15 × Part 1 + 0.15 × Part 2 + 0.30 × Part 3 + 0.40 × Part 4 (each as a percentage)
These are score weights, not question-count proportions. Part 4 has only 40 questions yet carries 40% of the composite, while Part 1 carries 15%. Reported scores are rounded down to a whole percentage, so a borderline result does not round up in your favor.
A strong Part 1 cannot rescue a weak Part 4, and the per-part floor means you cannot coast on one dominant section. The full mechanics are in CWEng Passing Score 2026: Exactly What You Need to Pass.
Fee Mechanics and Membership Pricing
The 2026 AWS price list, effective January 1, sets initial examination pricing in pairs, and the listed prices already include the applicable examination seat fees. Do not add seat fees on top.
| Item | Member | Nonmember |
|---|---|---|
| Parts 1 and 2 (initial) | $665 | $755 |
| Parts 3 and 4 (initial) | $705 | $795 |
| Retest, one of Parts 1 or 2 | $345 | $430 |
| Retest, both Parts 1 and 2 | $705 | $790 |
| Retest, one of Parts 3 or 4 | $365 | $450 |
| Retest, both Parts 3 and 4 | $745 | $830 |
The two member pair prices total $1,370 before reference materials and other optional costs. Nonmember initial examination prices include one year of AWS Individual Membership, so you should not automatically add the two nonmember pair prices into a single total; establish the applicable membership rate for each purchase instead. Student and Early Career membership do not qualify for the member discount.
For retests, the guide permits up to three within three years of the original exam date. A fuller breakdown, including how reference books affect your total, is in CWEng Certification Cost 2026: Complete Pricing Breakdown.
The Knowledge Prerequisites Nobody Lists
Meeting the experience route gets you into the exam room. It does not guarantee you can pass. The exams assume fluency in a specific set of subjects, and each percentage below applies only within its own part. They are not whole-credential weights and should not be normalized across all 19 headings.
Part 1: the science foundation
Part 1 covers Mathematics (25%), Physics (50%) and Chemistry (25%). Physics is half of this exam, so it deserves the largest share of your review time here. Welding engineers who have spent years on shop-floor problem solving often find that the underlying physics, rather than the welding, is what has gone rusty.
Part 2: applied engineering science
Part 2 covers Strength of Materials (40%), Heat Transfer and Fluid Mechanics (30%) and Electricity (30%). Strength of Materials is the heaviest block. Heat transfer and electricity are directly tied to arc welding behavior, so candidates with process experience often find these more intuitive than the mechanics material.
Part 3: welding-related disciplines
Part 3 covers NDE/Weld Discontinuities (10%), Welding Heat Sources and Arc Physics (20%), Welding Processes and Controls (20%), Welding and Joint Metallurgy (20%), Weld Design (20%), Brazing and Soldering (5%) and Safety (5%). The guide labels the Part 3 and Part 4 percentages as minimum percentages.
Part 4: applied practice
Part 4 covers Fabrication (25%), Filler Metals (15%), Inspection (20%), Productivity (10%), Welder Performance Qualification (10%) and Welding Procedure Qualification (20%). Fabrication is the largest block, and Part 4 as a whole drives 40% of your composite.
For the full content-area walk-through, see CWEng Exam Domains 2026: Complete Guide to All 19 Content Areas. Note that the count of 19 is the number of official examination-content headings reproduced across the four parts, not a preparation-curriculum count.
Reference rules affect what you must memorize
Parts 1 and 2 are closed book, so formulas and relationships must be internalized. Part 3 permits approved hardcopy references, including ANSI Z49.1, the AWS Welding Handbook volumes 1-5, Design of Weldments, and Welding Metallurgy and Weldability of Stainless Steels; digital copies are not supplied for Part 3. Part 4 permits AWS D1.1/D1.1M:2020, 24th edition, as its only reference. A hardcopy is permitted and an on-screen, non-searchable PDF is supplied. Do not transplant a different code edition allowed for another AWS exam.
Key Takeaway
Open book does not mean easy. In Parts 3 and 4, your edge comes from knowing where to find an answer quickly in the permitted references, so tab and annotate your hardcopies where the rules allow and practice with the exact D1.1 edition.
Sequencing Your Preparation Around the Rules
The rule that Parts 1 and 2 come first, and that you then have one year to apply for Parts 3 and 4, suggests a natural two-phase plan. Here is one way to align study with the structure:
Closed-book science (Parts 1 and 2)
- Start with Physics, since it is half of Part 1
- Move to Strength of Materials, the largest block in Part 2
- Drill formulas until you can reproduce them without notes
Application and scheduling window
- Finalize references and experience documentation
- Apply for Parts 3 and 4 well inside the one-year window
Open-book disciplines (Parts 3 and 4)
- Organize hardcopy references and practice lookups
- Spend extra time on Fabrication and Welding Procedure Qualification, the heaviest Part 4 blocks
For a deeper study plan, see the CWEng Study Guide 2026: How to Pass on Your First Attempt. One fact to plan around: the examined guide states that AWS does not offer a CWEng preparation seminar, so you are responsible for building your own preparation path. You can also test your readiness with questions from our CWEng practice test site. For a sense of what to expect, read How Hard Is the CWEng Exam? Complete Difficulty Guide 2026.
Version and Deadline Caveat for 2026
This is the part of the requirements picture most likely to trip people up, so read it carefully. The exam-specific Examination User Guide dated 05.06.2026 still cites AWS B5.16:2006 and supplies the four-part blueprint, question counts and timing used throughout this article. However, AWS also publishes AWS B5.16:2025, Specification for the Qualification of Welding Engineering Personnel, third edition, and its undated "Your Step-by-Step Pathway to CWEng" cites B5.16-2025.
The two documents also describe deadlines differently. The pathway guide states a three-year completion window measured from application approval, while the dated exam guide describes a retest window measured from the original exam date. These are different statements, and they are not interchangeable.
Keeping the Credential After You Qualify
Certification is valid for five years. Renewal requires a renewal application, 80 contact hours of relevant continuing education (or the permitted contact-hour/CEU equivalent) during the five-year period, and a fee of $605 for members or $870 for nonmembers. Routine renewal does not require another examination.
That makes the initial qualification the heavy lift. Whether the effort pays off for your career is a separate question, covered in Is the CWEng Certification Worth It? Complete ROI Analysis 2026 and CWEng Salary Guide 2026: Complete Earnings Analysis.
Frequently Asked Questions
No. An engineering bachelor's degree needs only one year of welding-based experience, but there are routes for engineering-technology degrees (two years), other related bachelor's degrees (five years), associate in applied science degrees (ten years), and high school or equivalent (fifteen years).
No. Parts 1 and 2 must be passed before Parts 3 and 4. After passing the last of Parts 1 and 2, you have one year to apply for Parts 3 and 4.
Possibly in part. AWS B5.16:2006 provides an FE-exam route for satisfying Parts 1 and 2, and a separate route for a state PE license specifically in welding engineering. AWS approval governs these exemptions, and the 2026 PE-exemption application fee is $480 member or $745 nonmember.
No. IIW International Welding Engineer and EWF European Welding Engineer diploma holders have a diploma-plus-one-year-experience eligibility route, but it is not an automatic substitution for the entire CWEng examination.
The dated AWS exam guide permits up to three retests within three years of the original exam date. Retest fees depend on which parts you retake and on your membership status, so check the current AWS price list before scheduling.
Qualifying for the CWEng is as much about documentation and sequencing as it is about engineering knowledge. Map your education and experience to the correct route, verify exemptions and deadlines with AWS in writing, and then build your preparation around the order the rules require.
