The AWS D17.1 endorsement is an open-book, 50-question, 2-hour Prometric exam taken by active CWIs and SCWIs who want to inspect aerospace fusion welds. You need 72% to pass and the fee is $445 for AWS members or $540 for nonmembers. The reference standard is AWS D17.1/D17.1M:2024 (4th edition, released 2024) which adds a new Clause 10 for crewed-spaceflight hardware and reorganizes the Clause 5 qualification tables. Questions emphasize Class A (fracture-critical), Class B (semi-critical), and Class C (non-critical) acceptance criteria, which are significantly tighter than AWS D1.1 structural acceptance limits.

About the AWS D17.1 Endorsement Exam
The AWS D17.1 Aerospace Welding Endorsement is an open-book add-on credential for active Certified Welding Inspectors (CWI) and Senior Certified Welding Inspectors (SCWI). The 50-question Prometric exam tests application of AWS D17.1/D17.1M:2024, Specification for Fusion Welding for Aerospace Applications, including weld classification (Class A, B, and C), qualification of procedures and personnel, fabrication and repair rules, inspection and NDE acceptance criteria, reports and records, and aerospace-specific materials and design considerations such as titanium discoloration limits, aluminum surface preparation, and crewed-spaceflight hardware requirements.

AWS D17.1 Endorsement Exam Content Outline
General Requirements & Weld Classification (Clause 4)
Scope, definitions, Class A fracture-critical welds, Class B semi-critical welds, Class C non-critical welds, drawing call-outs, and the relationship between weld class and inspection rigor.
Qualification of Procedures & Personnel (Clause 5)
WPS and PQR essential variables, welder and welding operator performance qualification, tack welder qualification, and the 2024 edition reorganization of Tables 5.1 through 5.7.
Fabrication (Clause 6)
Joint preparation, pre-weld cleaning, fit-up tolerances, preheat and interpass control, shielding gas requirements, tack welds, repair limits, and process-specific rules for aluminum, titanium, nickel-based, and iron-based alloys.
Inspection (Clause 7)
Visual inspection, radiographic testing, liquid penetrant testing, magnetic particle testing, ultrasonic testing, eddy current, leak testing, and how method selection follows weld class.
Weld Acceptance Criteria (Clause 8)
Class-specific limits for porosity, cracks, lack of fusion, incomplete penetration, undercut, underfill, concavity, convexity, mismatch, and titanium discoloration.
Aluminum & Titanium Aerospace Welding
Surface oxide removal for aluminum, hydrogen porosity control, titanium inert-gas shielding and trailing/backing shielding, beta transus considerations, and discoloration acceptance (silver, straw, blue, gray, white).
Nickel & Iron-Based Aerospace Alloys
Solidification cracking, hot cracking sensitivity, low heat input rules, PWHT, and stress-corrosion considerations for nickel-based superalloys and PH stainless steels.
Reports, Records & Traceability
WPS/PQR/WPQ retention, inspection report content, traceability of filler metals, and continuity records.
Crewed Spaceflight Hardware (Clause 10, new in 2024)
Additional rigor for crewed-spaceflight hardware including documentation, traceability, and Class A defaults.

Frequently Asked Questions
Do I need to be a CWI before I can sit for the D17.1 endorsement?
Yes. The AWS D17.1 endorsement is open only to candidates who hold an active CWI (Certified Welding Inspector) or SCWI (Senior Certified Welding Inspector) at the time of application. The endorsement is layered on top of those credentials and remains valid only while the underlying CWI/SCWI is current. If your CWI lapses, the endorsement lapses with it.
Is the D17.1 endorsement exam open book?
Yes. The 50-question multiple-choice exam is open book. At the Prometric test center you may rely on memory, use the electronic copy of AWS D17.1/D17.1M:2024 provided on the testing computer, or bring your own bound printed copy. Tabbing your specification and practicing fast lookups is the single biggest difference between candidates who pass and candidates who run out of time.
What edition of D17.1 is the 2026 endorsement exam based on?
The current exam is based on AWS D17.1/D17.1M:2024, Specification for Fusion Welding for Aerospace Applications. This is the fourth edition. Key changes from the 2017 version include separation of welding procedure and welder qualification criteria in Clause 5, a reworked set of Tables 5.1-5.7, and a brand-new Clause 10 covering crewed-spaceflight hardware.
How is a Class A weld different from a Class B or Class C weld?
AWS D17.1 sorts every weld into three criticality classes. Class A welds are fracture-critical and flight-critical; a Class A failure would compromise a critical system or the entire vehicle, so acceptance criteria are extremely tight. Class B welds are semi-critical and reduce strength or function if they fail. Class C welds are non-critical, often cosmetic or for ground-support hardware, and the acceptance limits are the most permissive of the three.
How much does the D17.1 endorsement cost in 2026?
The 2026 endorsement application fee is $445 for AWS members and $540 for nonmembers. You will also need a copy of the AWS D17.1/D17.1M:2024 specification for study (AWS sells print and PDF versions). Most candidates also budget for a focused review seminar or online course, though no prep course is required by AWS.
How long should I study for the D17.1 endorsement?
Most CWIs with some aerospace exposure spend 40-80 hours preparing. Plan to read AWS D17.1/D17.1M:2024 cover to cover at least twice, build a tabbed open-book index of every Clause 5 qualification table and every Clause 8 acceptance table, and run several timed 50-question simulations. Heavy use of the spec during practice is the most effective way to build the lookup speed the exam rewards.
