AWS D17.1 Endorsement study guide
AWS D17.1 Endorsement · Work through your exam, one topic at a time.
The Aerospace (D17.1) endorsement is one of the CWI and SCWI endorsements listed by the American Welding Society alongside Structural Steel (D1.1), Structural Aluminum (D1.2), Bridge Welding (D1.5), Railroad (D15.1), Pipeline (API 1104), and several NDE and coordination endorsements. It is designed for inspectors who already hold or are pursuing AWS inspector credentials and who want to demonstrate code-specific knowledge of aerospace fusion welding practice rather than general structural work. Aerospace work differs from structural fabrication in its emphasis on procedure and personnel qualification, documentation discipline, and acceptance criteria for hardware where failure is not an option, so the endorsement signals that a CWI can read and apply aerospace requirements rather than only D1.1. Candidates typically prepare by studying the D17.1 specification itself, its qualification requirements for procedures and welders, and the inspection and acceptance provisions an inspector applies on the shop floor. Because AWS publishes endorsement-specific application instructions and a program price list, candidates should confirm current eligibility, scheduling, and fees through the My AWS Portal and the Program Price List rather than relying on secondhand summaries. Note that beginning January 15, 2026, AWS will no longer accept paper applications for Certifications or Endorsements. Topics on this exam: Aerospace (D17.1) endorsement content. The AWS D17.1 Endorsement study guide has 1 section and about 485 words.
01AWS D17.1 Aerospace Fusion Welding: Scope, Governance, and Certification Logic
AWS D17.1 governs fusion welding of metallic components for aerospace applications. The endorsement exam tests whether you understand how the specification is structured and how responsibility is allocated, not whether you can recite a table. Start with scope: D17.1 applies to production and repair welding of aerospace hardware where a contract invokes it. It is a specification, not a how-to manual, so it deliberately defers to the engineering authority for design values and to the manufacturer for process detail.

- Practice questionsUnder AWS D17.1, which document defines the welding procedure qualification requirements for aerospace fusion welding?
- FlashcardsD17.1 scope. AWS D17.1 specifies requirements for fusion welding of aerospace hardware, covering base metals such as aluminum, titanium, steel, nickel, cobalt, and magnesium alloys, plus qualification, fabrication, and inspection rules.
- Cheat sheetAWS D17.1 governs fusion welding of aerospace components in aluminum, titanium, steel, nickel, cobalt, and magnesium alloys; it is a specification of requirements rather than a how-to guide.
- Key termsAWS D17.1. The American Welding Society specification that sets qualification and inspection requirements for fusion welding of aerospace hardware, covering design, procedure and performance qualification, fabrication, and examination.
- Study planMap the scope of AWS D17.1 by outlining its structure clause by clause and labeling which clauses govern aerospace fusion welding of steel, titanium, aluminum, and nickel alloys.
- Common mistakesMost candidates come from a general welding inspection background where D1.1 is the default mental model, and the endorsement exam tests a specification written for fusion welding of aerospace hardware with its own classification, qualification, and acceptance structure.
