Experimental Tests and Material Characterization

• Directing and supervising material characterization and large-scale testing
  For large scale, e.g., curved wide plates and full-scale pipes, and unique tests, provide

  1. Specifications for specimens geometries
  2. Instrumentation plan
  3. Post-test data analysis
  4. Assessment of the significance of test data
• Mechanical testing of vintage pipes and welds
  1. Tensile strength of pipe and weld
  2. Charpy transition curves
  3. Weld strength mismatch
  4. Microhardness maps
  5. Instrumented cross-weld testing with or without weld flaws
  6. Determination of apparent CTOD toughness
• Characterization of weld anomalies
  1. Type and size of anomalies
  2. Confirmation of NDT techniques
