Failure Analysis – Developing Engineering Solutions 

Failure analysis investigations and developing engineering solutions on equipment & structures to prevent recurrence. Our team of experts in engineering, metallurgy & welding investigate the root cause of structural failures due to thermal / transients, vibrations, thermal fatigue, etc., to ensure structural integrity, and maximize equipment reliability – ultimately controlling costs for owners/ users.

Applications include aluminum, stainless & alloy steels, titanium, and other materials used in industries including Aerospace, Petrochemical, Automotive, Medical, and Energy.

Although Many Components Break due to Fatigue Failure – Quite Often there are Additional Factors Involved – Including Coatings, Corrosion, Damage, Abuse, and Improper Manufacture.  Contact Us to Learn More.

  • Root Cause Failure Analysis

    Components that don’t meet their intended design life, or experience accidents and failures typically occur due to Vibration & Fatigue, but other factors may include:
    • Design Errors
    • Material Imperfections
    • Manufacturing Issues
    • Weld Issues
    • Improper Heat Treatments
    • Fatigue / Fracture
    • Misuse or Abuse
    • Improper Maintenance
    • Unforeseen Operating Conditions
    • Inadequate Quality Assurance
    • Environmental Issues (Vibration, Corrosion, etc.)

    Interdisciplinary teams are essential for performing most failure analyses, since the root cause is rarely the result of a single variable. In performing metallurgical failure analysis, we investigate operational issues, environmental factors, load paths and stresses to a system or component.

    Once we identify potential component failure modes, we design solutions & recommend inspection methods/ intervals to reduce the likelihood of future failures.


    In elevated temperature applications, complicated failure modes may occur, such as creep ratcheting, rupture, and creep fatigue. Our engineers have the expertise, technology, and experience to identify and quantify these failure modes – helping you understand the root cause and developing solutions to prevent costly recurrences, thus improving safety and lowering operating costs.

    Examples Include:

    • Heat Exchangers
    • Bellows
    • Reactors
    • Petrochemical
    • Oil/ Gas
    • Power Generation
    • Refractory
    • Ductwork
    • Compressors
    • Heaters
    • Welded Assemblies

    Metallurgical Testing

    Failure analysis consulting requires metallurgical testing to evaluate the root cause of component failure, including corrosion investigations, surface condition studies, mechanical testing, and weld evaluations. This testing includes Chemical, Mechanical, Corrosion, Metallographic and Fractography (SEM & TEM).
