    AMS 5853 — A286 Welding Wire and Filler Rod

    AMS 5853 is the SAE Aerospace Material Specification covering A286 (UNS S66286) welding wire and filler rod for TIG (GTAW), MIG (GMAW), SAW (submerged-arc), and plasma-arc welding of A286 base metal. The dominant aerospace welding-filler spec for matching A286-to-A286 weld joints. Material is supplied in solution-treated condition — NOT aged — so it can be welded without strain-age cracking. Post-weld solution-treatment + aging restores parent-metal-equivalent mechanical properties to the weld zone. Filler diameter range 0.8-3.2 mm; supplied as straight rod (1-2 m) for TIG or coiled wire (15 kg spool) for MIG. See parent A286 AMS specifications hub, related A286 welding rod product page, and the canonical A286 weldability & welding rod.

    Spec Scope & Coverage

    AMS 5853 covers A286 welding wire and rod in solution-treated condition for fusion welding. Material is VIM-VAR melted, cold-drawn through progressive dies to filler diameter (0.8-3.2 mm), bright-annealed in hydrogen atmosphere to restore ductility, final solution-treated, and surface-cleaned for welding. Used as matching weld filler for A286 base-metal welding in jet-engine combustor repair, gas-turbine welding, aerospace structural component fabrication, and pressure-vessel weld overlay.

    When to Specify AMS 5853 — A286 Welding Wire and Filler Rod

    • Aerospace TIG welding (GTAW): AMS 5853 1.6-2.4 mm straight rod for TIG welding of A286 base metal. Argon shielding 15-20 L/min. Pre-heat NOT required for ≤ 50 mm thickness.
    • MIG welding (GMAW) production: AMS 5853 coiled wire 0.8-1.6 mm for MIG production welding. Argon-helium-CO₂ shielding mix.
    • Plasma arc welding: AMS 5853 0.8-1.6 mm filler — used for jet-engine combustor and turbine blade repair where narrow weld bead is critical.
    • SAW (submerged-arc): Coiled AMS 5853 wire 1.6-3.2 mm with granular flux — used for thick-section structural welding.
    • Post-weld heat treatment: Welded assembly post-weld solution-treated 1650 °F + aged 1325 °F × 16 h to develop full A286 properties in weld zone.
    • Aerospace welding standards: AMS 5853 is referenced in MIL-W-46086, AWS A5.9 ER660 classification.

    AMS 5853 — A286 Welding Wire and Filler Rod — Frequently Asked Questions

    What is AMS 5853?

    SAE / AMS spec covering A286 (UNS S66286) welding wire and filler rod for TIG / MIG / SAW welding of A286 base metal. The dominant aerospace welding-filler spec — material ships in solution-treated (NOT aged) condition for weldability.

    Is AMS 5853 the same as AWS A5.9 ER660?

    AMS 5853 is the aerospace SAE/AMS classification; AWS A5.9 ER660 is the American Welding Society equivalent classification. TorqBolt AMS 5853 conforms to AWS A5.9 ER660 acceptance. Both reference UNS S66286 chemistry.

    What welding processes use AMS 5853?

    TIG (GTAW) most common — straight 1-2 m rod 0.8-3.2 mm diameter. MIG (GMAW) — coiled wire 0.8-1.6 mm. SAW (submerged-arc) — coiled wire 1.6-3.2 mm. Plasma-arc welding — 0.8-1.6 mm. All A286-to-A286 matching welding.

    Why is AMS 5853 supplied solution-treated, not aged?

    Aged A286 is susceptible to strain-age cracking during welding. Sol-treated is the correct starting condition — the weld pool melts the filler, then post-weld solution-treatment + aging develops the gamma-prime precipitates in the weld zone, restoring full mechanical properties.

    What's the post-weld heat treatment for AMS 5853?

    Solution-treat 1650 °F (899 °C) for 1 h per inch of section + oil-quench → precipitation-age 1325 °F (718 °C) for 16 hours + air-cool. This develops gamma-prime in weld zone, restoring base-metal-equivalent properties (130 ksi tensile / 95 ksi yield).

    What size AMS 5853 filler for 5 mm A286 base metal?

    1.6 mm (1/16 inch) TIG rod — typical filler-to-base-metal-thickness ratio is 0.3-0.4. For 5 mm: 1.6 mm filler at 100-130 A welding current. For thinner 1-3 mm: 1.0-1.2 mm filler at 60-90 A.

    What's the shelf life of AMS 5853 welding rod?

    Indefinite when stored sealed in dry conditions (≤ 60 % humidity). After opening: use within 6 months. Surface oxide spots indicate contamination — re-pickle in HNO₃ + HF before use.

    Is AMS 5853 magnetic?

    No. Magnetic permeability < 1.005 verified per ASTM A342. Critical when welding non-magnetic A286 components — base metal AND weld must remain non-magnetic for the assembly to maintain magnetic isolation.

    Can AMS 5853 be used to weld A286 to dissimilar alloys?

    For some combinations — A286-to-Inconel 718, A286-to-stainless 304/316, A286-to-17-4 PH. Verify weldability with welding-procedure qualification per ASME IX or AWS D1.6 before production. Not all dissimilar combinations produce sound welds.
