SAE AMS4953J-2024 PDF

Full title and description

SAE AMS 4953J-2024 — Titanium Alloy Welding Wire, 5Al - 2.5Sn. This aerospace material specification defines requirements for titanium alloy supplied in the form of welding wire (see clause 8.5 in the full text), including composition, manufacture, inspection and delivery conditions for use as filler metal in welding of titanium components.

Abstract

AMS 4953J (issued April 2024) is the J revision of the long‑running AMS4953 series and provides the up‑to‑date technical and quality requirements for titanium alloy welding wire designated nominally as 5Al-2.5Sn. The document is intended to assure metallurgical and dimensional conformity of welding wire used in aerospace and other high‑reliability applications.

Scope

The specification covers the designation, chemical and metallurgical requirements, acceptable manufacturing processes, dimensional and surface condition requirements, test and inspection methods, marking, packaging and delivery requirements for titanium alloy welding wire whose nominal composition is 5% aluminium, 2.5% tin (balance titanium). It is intended for use as filler wire in welding and repair of titanium alloy components in aerospace and related industries.

Key topics and requirements

• Chemical composition and alloy designation: wire specified as the 5Al‑2.5Sn titanium alloy (nominal composition).
• Form and condition: requirements for wire form (spool/straight/coil), surface condition and any heat‑treatment or anneal conditions required for welding filler metal.
• Manufacture and melting practice: controls on melting/refining and wire production processes to ensure clean metallurgy and low interstitials appropriate for aerospace weldability.
• Dimensional tolerances and mechanical properties: diameter tolerances, tensile/bend tests and acceptance criteria appropriate for filler wire use.
• Inspection, testing and certification: chemical analysis, mechanical testing, surface inspection, and traceability/lot identification and documentation requirements.
• Marking, packaging and handling: labeling, preservation and packaging rules to prevent contamination and maintain weldability.

Typical use and users

Primary users are aerospace OEMs, tier suppliers, aircraft maintenance/repair organizations (MROs), and specialized welding/filler‑metal manufacturers. Typical uses include gas tungsten arc welding (GTAW/TIG), gas metal arc welding (GMAW/MIG) and other welding processes where 5Al‑2.5Sn filler is required for joining or repair of titanium alloy structures, tubing and components in aircraft, spacecraft and high‑performance industrial equipment.
