TECHNOLOGY CHANGES OVER TIMEFrom These: To These:

But what about the technology changes in NDT?

TECHNOLOGY CHANGES IN NON-DESTRUCTIVE TESTING

• For centuries blacksmiths used sonic techniques to shape metals by their ringing sound

• 1912 - First application of ultrasonic testing proposed

• 1920 - Industrial radiography for metals begins for castings, welds, armor

• 1926 - First electromagnetic eddy current unit available in NDE equipment

• 1950 - Kaiser introduces acoustic emission techniques

INSPECTION PROGRESS AND CHALLENGES

• Corrosion costs continue to soar with the annual cost in the U.S. being over one trillion dollars

New Challenges:

• To Assess Material Health

- Aging - Properties - Specifications

- Stability - Strain State

• To non-destructively characterize material properties in technical assemblies

• To rapidly perform real-time testing, data acquisition, and assessment, to qualify materials during manufacturing, processing, and use

PROACTIVE INTEGRITY MANAGEMENT• Stages of Material Life (Stages of

Materials)

• Birth (Casting, HIP, or other production)

• Growing Up (Welding, Forging, Heat Treating, etc)

• Maturity (Optimizing the Final Product)

• Aging (Lifetime)

• Death (Failure)

• Post-Mortem (Failure Analysis)
