Frequently Asked Questions
Who is eligible to take the AWS D1.1 Endorsement?
Only candidates with an active AWS CWI or SCWI certification may take the D1.1 Endorsement. It is not available to CAWIs, welders, or general AWS members. Your base CWI must be current (not expired and not in suspension) at the time you register and on the day you sit for the test at Prometric.
Is the AWS D1.1 Endorsement open book?
Yes. The D1.1 Endorsement is fully open book. AWS provides an electronic copy of D1.1/D1.1M:2025 on the Prometric testing workstation, and you may also bring your own bound printed copy of the same edition. No other references, handbooks, or notes are allowed, and the codebook must match the referenced edition for the cycle in which you test.
How many questions are on the D1.1 Endorsement and how long is the test?
The endorsement is approximately 50 multiple-choice questions delivered in 2 hours at a Prometric test center. That gives you roughly 2 to 2.5 minutes per question. Each question carries about 2% of the total, so you cannot afford to misread several items if you want to clear the 72% pass mark.
What is the passing score for the D1.1 Endorsement?
You must achieve a minimum overall score of 72% to pass the D1.1 Endorsement. This matches the 72% threshold used across CWI Parts A, B, and C and the other CWI endorsements. There is no separate domain pass; the 72% applies to the total scored items.
How much does the D1.1 Endorsement cost in 2026?
The 2026 AWS price list lists the D1.1 Endorsement at $445 for AWS members and $540 for non-members. The fee is paid to AWS at registration. If you fail, the retake fee is equivalent to the original endorsement fee, so a single failure can effectively double the cost.
What is the difference between Clause 5 (Prequalification) and Clause 6 (Qualification)?
Clause 5 lets you write a WPS without testing IF every variable falls inside the prequalified limits (approved processes, base metals from Table 5.3, matching filler metal, prequalified joint details, preheat from Table 5.8, etc.). Clause 6 is the path you must follow when any variable falls outside Clause 5 - you weld a test coupon, run mechanical tests, and document the result on a PQR. The endorsement frequently tests this boundary, so memorize the Clause 5 limits cold.
