AWS D17.1 - D17.1M-2024 PDF

Full title and description

D17.1/D17.1M:2024 — Specification for Fusion Welding for Aerospace Applications. This American Welding Society (AWS) specification provides the general welding requirements for aircraft and space hardware, covering fusion welding of aluminum-, nickel-, iron-, cobalt-, magnesium- and titanium-based alloys by electric arc and high-energy beam processes, and includes personnel/procedure qualification, fabrication, inspection, nondestructive examination (NDE), acceptance criteria, and repair requirements.

Abstract

This specification establishes requirements for the fusion welding and NDE of aerospace flight hardware and for non‑flight/support hardware when the specification is called out by contract or engineering authority. It addresses welding design, procedure and personnel qualification, fabrication controls, inspection and acceptance criteria, repair welding, and additional requirements for crewed spaceflight hardware. A commentary accompanying the specification is included in the 2024 edition.

General information

Scope

The standard covers fusion welding processes used in aerospace production and repair, including requirements for commonly used electric-arc and high-energy beam welding processes and for a broad set of metallic aerospace alloys. It sets out mandatory requirements for welding design, qualification of procedures and personnel, fabrication controls, inspection (including NDE) and acceptance criteria for flight hardware, nonflight/support hardware, and crewed spaceflight hardware (where applicable); it also provides guidance for repair welding and includes an explanatory commentary.

Key topics and requirements

• Materials and processes: fusion welding of aluminum, titanium, nickel, iron, cobalt and magnesium alloys.
• Welding design requirements and engineer/Engineering Authority responsibilities.
• Qualification of welding procedures (WPS/PQR) and performance-based procedure controls.
• Personnel qualification and certification requirements for welders and welding operators.
• Fabrication controls: fit-up, preheat/postweld treatment, contamination control, and process parameters.
• Inspection and NDE methods, acceptance criteria, and documentation/records.
• Repair welding procedures and special requirements for crewed spaceflight hardware.
• Commentary included to explain intent and application of specification clauses.

Typical use and users

Used by aerospace manufacturers, aircraft and spacecraft integrators, repair and overhaul facilities, welding engineers, welding supervisors, certified welding inspectors (CWIs), senior CWIs, and qualified welders/operators working on flight and support hardware. The D17.1 code is also the basis for the AWS D17.1 endorsement and related training (code clinic) for CWIs/SCWIs.

Related standards

Related documents typically referenced or used in conjunction with D17.1 include AWS standards on inspector qualification and welding procedure/consumables (for example AWS B5.1 and various AWS A5.x material/consumable specifications), aerospace material specifications (AMS/SAE), ISO welding procedure and personnel qualification standards, and applicable regulatory texts such as FAA requirements where aircraft certification is involved.

FAQ

Q: What is this standard?

A: D17.1/D17.1M:2024 is the AWS specification that defines fusion welding practice and requirements for aerospace applications (aircraft and spaceflight hardware), including fabrication, inspection, NDE, and qualification requirements.

Q: What does it cover?

A: It covers fusion welding processes (electric arc and high‑energy beam), applicable alloys (Al, Ti, Ni, Fe, Co, Mg), welding design, procedure and personnel qualification, fabrication controls, inspection/NDE, acceptance criteria, repair requirements, and additional provisions for crewed spaceflight hardware. A commentary explaining clauses is included in the 2024 edition.

Q: Who typically uses it?

A: Aerospace manufacturers, repair/overhaul organizations, welding engineers, welding supervisors, welders and welding operators, and certified welding inspectors preparing for or holding the AWS D17.1 endorsement. Training and code‑clinic resources are available from AWS for users preparing to work with the code.

Q: Is it current or superseded?

A: The 2024 edition (D17.1/D17.1M:2024) is the current AWS edition issued in 2024 and supersedes the prior D17.1 edition used before 2024. (Published as the 4th edition in 2024.)

Q: Is it part of a series?

A: Yes. D17.1 is produced by the AWS D17 committee on Welding in the Aircraft and Aerospace Industries and is part of the AWS family of standards addressing welding processes, consumables and qualification; it is commonly used alongside other AWS, AMS/SAE, and ISO standards referenced in its normative references.
