Dams are complex structures that require frequent inspection by experts to ensure safe and uninterrupted service. TKS performs inspection of spillway gates and other dam apparatus using a variety of NDE methods.
-
Shear-wave Ultrasonic Testing (UT) of Complete Joint Penetration welds
-
Conventional straight-beam UT of pins, bearings and trunnions
-
Magnetic Particle Testing (MT) of fillet welds
-
Magnetic Flux Leakage (MFL) of steel cables
-
Alternating Current Field Measurement (ACFM) of welds
-
Visual Inspection of weld rework on gates and stop logs
-
QA/QC of welding practices
TKS inspects to a variety of codes. If you are unsure of the code compliance requirements, WINS-NDT’s ASNT Level 3 can provide suggestions or develop a procedure for your specific application. Some examples of codes that govern the acceptance/rejection criteria of dam members are:
-
AASHTO/AWS D1.1/D1.1M – Structural Welding Code – Steel
-
AASHTO/AWS D1.5/D1.5M – Bridge Welding Code
-
ASTM E587 – Standard Practice for Ultrasonic Angle-Beam Contact Testing
-
ASTM E114 – Standard Practice for Ultrasonic Pulse-Echo Straight-Beam Contact Testing
-
ASTM E1571 – Standard Practice for Electromagnetic Examination of Ferromagnetic Steel Wire Rope
-
ASTM E2261 – Standard Practice for Examination of Welds Using the Alternating Current Field Measurement Technique
