Why OES Testing Matters
In flight-critical and high-pressure environments, alloy chemistry drives strength, fatigue life, corrosion resistance, and weld performance. OES quantifies alloying and trace elements in base material and weldments to verify specification conformance (ASTM, B954, E415, E1086, E1251, E1999, E2994, E3047), prevent mix-ups, and support MRB decisions, before parts move downstream to machining, heat treat, or assembly.
AADFW’s Approach to OES: Precision, Speed, and Proof
- Accredited & precise: Procedures aligned to ISO/IEC 17025 with certified reference materials, matrix-matched calibration curves, and documented uncertainty.
- Faster results: Streamlined intake, expert operators, and right-sized reporting compress lead times without compromising rigor.
- Trusted by industry: Selected by aerospace and oil & gas teams for clear, defensible chemistry that closes quality loops and reduces risk.
OES Service Capabilities
- Arc/Spark OES for ferrous & nonferrous alloys: Steels (carbon & low-alloy, stainless), nickel/cobalt superalloys, aluminum, titanium, and copper/brass/bronze.
- Multi-element quantification: Major, minor, and trace elements, including carbon, sulfur, phosphorus, boron, and nitrogen (on equipped matrices).
- Positive Material Identification (PMI): Heat/grade verification for incoming inspection, in-process checks, and final release.
- Weld & overlay verification: Base/filler chemistry checks, dilution assessment, and repair validation.
- Mix-up prevention & segregation control: Rapid screening of bars, forgings, plates, fasteners, and fabrications.
- Methodology & QA: Matrix-specific programs, daily drift checks, control samples, and instrument maintenance records included with reports.
- Sampling & prep: Surface conditioning per method requirements (grinding/finish), with alternate prep for coated/oxidized parts.
