Overview
EN 3888:2001 is a CEN/AECMA aerospace material standard that defines the requirements for the heat-resisting filler metal CO‑WH1402 (CoCr22Ni22W15) used for welding in aerospace applications. It is part of the EN metallic materials series for aerospace and establishes composition, manufacture and delivery requirements for filler wire and filler rods intended to join high‑temperature components.
Key topics and technical requirements
- Material designation: CO‑WH1402, also written as CoCr22Ni22W15 (indicative of ~22% Cr, ~22% Ni, ~15% W, balance cobalt).
- Intended use: Filler metal specifically for welding heat‑resisting cobalt‑based alloys in aerospace service.
- Forms: Supplied as filler wire and filler rods.
- Manufacturing route:Consumable electrode remelted melting method; production by cold drawing.
- Delivery condition: Supplied cold drawn and annealed (delivery condition per the standard).
- Product qualification & inspection: References EN 3879 (technical specification for filler metals) and EN 2043 (general requirements for semi‑finished product qualification). Batch uniformity, dimensional and marking inspections and other verification requirements are handled per these cross‑referenced standards.
- Standard series context: Prepared in accordance with EN 4500‑3 and organized under the aerospace metallic materials series described in EN 4258.
Applications
- Welding filler for heat‑resisting cobalt‑based alloys used in aerospace structures and components subject to elevated temperatures.
- Typical users include aerospace manufacturers, welding consumable producers, welding engineers, repair and maintenance organizations, and quality/standards teams specifying materials for high‑temperature joining.
- Useful for procurement specifications and supplier qualification when selecting filler wire/rod for high‑temperature welding in aircraft and aero‑engine assemblies.
Who uses this standard
- Welding consumable manufacturers producing CO‑WH1402 filler metals.
- Aerospace OEMs and subcontractors specifying welding materials for heat‑resisting applications.
- Quality assurance, materials engineering and inspection personnel ensuring compliance with aerospace material requirements.
- Certification and procurement teams referencing standardized alloy compositions and delivery conditions.
