Dye Penetrant Testing (PT) Services for Aerospace & Oil & Gas 

Fast, Accredited Surface-Crack Detection  

Why Dye Penetrant Testing (PT) Matters 

In flight-critical structures and high-pressure systems, surface discontinuities drive leaks, fatigue initiation, and premature failures, especially around welds, machined features, and fastener interfaces. PT provides rapid, economical screening to confirm code and drawing compliance (e.g., weld acceptance criteria), support MRB decisions, and de-risk downstream operations. PT complements other NDT methods (MT/RT) by targeting fine, surface-open flaws on ferrous and nonferrous alloys. 

AADFW’s Approach: Precision, Speed, and Proof 

• Accredited & precise: Procedures aligned to ISO/IEC 17025 within a controlled quality system, documented sensitivity level selection, dwell and development times, removal method, and lighting verification. ASTM E1417/E14AM, BPS 4089, S5806, BSS7039 

• Faster results: Streamlined scheduling, standardized work instructions, and photo-documented reports enable quick disposition without sacrificing rigor. 

• Trusted by industry: Aerospace, oil & gas, and advanced manufacturing teams rely on our audit-ready documentation, traceability, and clear go/no-go guidance. 

Dye Penetrant Testing Capabilities 

• Visible (Color-Contrast) & Fluorescent PT – Selection by sensitivity and environment: visible for field/daylight practicality; fluorescent for maximum sensitivity under controlled UV-A lighting. 

• Sensitivity Levels & Families – Level 1–4 fluorescent; water-washable, post-emulsifiable (lipophilic/hydrophilic), and solvent-removable systems matched to part geometry and surface finish. 

• Weld Inspection – Root/face pass evaluation, repair verification, and final acceptance for plate and pipe welds; scribe/heat-affected zone focus where specified. 

• Surface Prep & Cleanliness – Pre-cleaning methods validated for the alloy/coating; compatibility checks for aluminum, titanium, nickel superalloys, and coated/anodized surfaces. 

• Process Controls – Dwell, removal, and development timed per procedure; UV-A intensity and visible light (lux) checks; temperature/humidity controls; system performance (tamarack/known-defect panels). 

• Indication Evaluation – Linear vs. rounded characterization, length/width measurement, clustering; acceptance per drawing/spec. 

• Documentation – Photo evidence, indication maps, inspection parameters, environmental readings, and inspector certification—audit-ready reports. 

Industries We Support 

• Aerospace: Airframe structures, landing gear, engine-adjacent hardware; OEM/FAA expectations for fine crack detection on high-performance alloys. 

• Oil & Gas: Pipeline/tubular welds, valve bodies, pressure components, and overlays/cladding where leak-tightness and safety are critical. 

• Defense & Manufacturing: Mission-critical assemblies and precision machined parts requiring reliable surface integrity. 
  Trusted by engineers and QC managers across mission-critical industries.
