AMS 5805 — A286 Welding Electrode
AMS 5805 is the SAE Aerospace Material Specification covering A286 (UNS S66286) welding electrode for SMAW (shielded-metal-arc, stick) welding of A286 base metal. Distinguished from AMS 5853 by welding process — AMS 5805 is for stick electrode welding; AMS 5853 is for TIG / MIG filler wire. Both produce matching A286-to-A286 weld joints. See parent A286 AMS / ASTM specifications hub, related A286 welding rod, sister spec AMS 5853.
Spec Scope & Coverage
AMS 5805 covers A286 welding electrode for SMAW (stick) welding. Material is VIM-melted ingot, cold-drawn to electrode core diameter 2.4-4.0 mm, then coated with flux for stick-electrode welding. Used for repair welding and structural welding where SMAW (manual stick electrode) is the welding process choice.

When to Specify AMS 5805 — A286 Welding Electrode
- SMAW repair welding: AMS 5805 stick electrode for field repair welding of A286 components — combustor liner cracks, structural component repair.
- Heavy-section welding: AMS 5805 4.0 mm electrode for thick-section A286 structural welding where TIG (AMS 5853) is impractical.
- TIG / MIG alternative: For TIG (GTAW) and MIG (GMAW) welding, specify AMS 5853 wire/rod instead.
- Combined process welding: Use AMS 5805 stick for root pass + AMS 5853 wire for fill / cap pass on multi-process welding.

AMS 5805 — A286 Welding Electrode — Frequently Asked Questions
What is AMS 5805?
SAE / AMS spec covering A286 (UNS S66286) welding electrode for SMAW (shielded-metal-arc, stick) welding. Used for matching A286-to-A286 weld joints in SMAW process.
AMS 5805 vs AMS 5853 — which to specify?
AMS 5805: SMAW (stick electrode) welding. AMS 5853: TIG / MIG / SAW filler wire. Choose by welding process — most aerospace applications use AMS 5853 (TIG); AMS 5805 is for SMAW field repair and heavy-section structural welding.
What flux coating on AMS 5805?
Basic (low-hydrogen), cellulosic, or rutile per drawing. Basic flux preferred for high-strength applications and crack-resistant deposits.
Is AMS 5805 ABT (low-hydrogen) coated?
Basic-coated AMS 5805 electrodes are low-hydrogen. Hydrogen-induced cracking is rare in austenitic A286 weld zones, but low-hydrogen practice is still recommended for thick-section structural welding.
Is AMS 5805 the same as AWS A5.11 ER660?
AMS 5805 is the aerospace SAE/AMS classification; AWS A5.11 ER660 is the American Welding Society equivalent classification. TorqBolt AMS 5805 conforms to AWS A5.11 ER660 acceptance.
What's the post-weld heat treatment for AMS 5805?
Solution-treat 1650 °F + age 1325 °F × 16 hours. Restores parent-metal-equivalent properties to weld zone. Without post-weld heat treatment, weld zone is at 60-70 % of base-metal properties.
Is AMS 5805 magnetic?
No — deposit is non-magnetic with permeability < 1.005.
What's the shelf life of AMS 5805 electrodes?
12 months in sealed containers; 4 hours after opening (basic-coated low-hydrogen). Re-bake at 250-300 °C for 2 hours if exposed to moisture.
Can AMS 5805 weld A286 to other alloys?
For some combinations — A286-to-Inconel 718, A286-to-stainless 304/316. Verify weldability with welding-procedure qualification per ASME IX before production.
