The AWS D1.5 Endorsement is a 50-question open-book exam at Prometric, with a 2-hour time limit and a 72% passing score. The fee is $445 for AWS members and $540 for non-members in 2026. Candidates must already hold a current CWI or SCWI. The exam emphasizes Clause 12 (Fracture Control Plan for nonredundant FCM members), CVN testing zones (T1/T2/T3 and F1/F2/F3), AASHTO M270 (A709) steel grades, and bridge-specific NDT/UT/RT acceptance criteria. Most candidates study 60-100 hours over 4-8 weeks using the AASHTO/AWS D1.5:2020 Bridge Welding Code as their primary reference.

About the AWS D1.5 Endorsement Exam
The AWS D1.5 Bridge Welding Endorsement is a supplemental credential for active Certified Welding Inspectors (CWIs) and Senior Certified Welding Inspectors (SCWIs) who work on highway bridge fabrication and erection. The 50-question, open-book exam at Prometric tests in-depth knowledge of the AASHTO/AWS D1.5 Bridge Welding Code, including fracture critical members (FCM) under Clause 12, Charpy V-notch (CVN) requirements, AASHTO M270 (A709) base metal grades, prequalified WPSs, and bridge-specific NDT acceptance.

Frequently Asked Questions
What is the AWS D1.5 Endorsement and who is eligible?
The D1.5 Endorsement is a supplemental credential that demonstrates a CWI or SCWI's mastery of AASHTO/AWS D1.5 Bridge Welding Code. To sit for the endorsement, you must hold a current CWI or SCWI certification in good standing. The endorsement is widely required for inspectors working on state DOT highway bridge projects and for FCM fabricator certification.
How many questions are on the D1.5 Endorsement exam and how long is it?
The D1.5 Endorsement is 50 multiple-choice questions with a 2-hour time limit. It is open-book, delivered as a CBT at Prometric, and you may use the electronic D1.5 codebook provided in the system or bring your own printed bound copy. The passing score is 72%.
How much does the AWS D1.5 Endorsement cost in 2026?
The 2026 fee is $445 for AWS members and $540 for non-members. The fee covers one attempt. Retests are billed separately. Most candidates also invest in the D1.5 codebook ($650-$800 list price for the 2020 edition) and optionally a 3-5 day prep seminar.
What does Clause 12 (Fracture Control Plan) cover, and why does it dominate the exam?
Clause 12 governs nonredundant 'fracture critical members' (FCMs) - tension members whose failure could collapse the bridge. It imposes higher CVN toughness (F-designators vs T-designators), 100% volumetric NDT plus MT, AISC FCM-certified fabricators, written Fracture Control Plans, Engineer-approved repair procedures, tighter electrode controls, and stricter UT/RT acceptance. Roughly 15% of exam items focus on Clause 12 because errors here have catastrophic consequences.
What is the difference between D1.5 and D1.1?
D1.5 is for highway bridges and is jointly published with AASHTO; D1.1 is for general structural steel. D1.5 always requires CVN testing on PQR, prohibits GMAW-S, has tighter workmanship limits in tension members, references AASHTO M270 (A709) base metals, and adds Clause 12 for FCMs. D1.1 PQRs typically do not require CVN unless contract documents demand it, and D1.1 does not have an FCM clause.
How should I prepare for the D1.5 Endorsement?
Plan 60-100 study hours over 4-8 weeks. Buy the AASHTO/AWS D1.5:2020 Bridge Welding Code and tab the major clauses (especially 5, 6, and 12). Practice 100+ questions on FCM/CVN, prequalified WPSs, and NDT acceptance to build codebook lookup speed - since the exam is open-book, finding answers fast is more valuable than memorization. Take a final timed practice exam at 72% target.
