ASTM E164
Full Name
ASTM E164 – Standard Practice for Contact Ultrasonic Testing of Weldments
Scope
ASTM E164 outlines procedures for the ultrasonic examination of weldments using the reflection method. This non-destructive testing method utilizes sound waves to detect internal discontinuities, ensuring the quality and integrity of welds in a wide range of applications.
This standard practice finds application in various welding processes, including but not limited to:
- Fusion welding of materials: this encompasses a variety of metals like carbon steel, stainless steel, aluminum, and nickel alloys.
- Weldments in diverse forms: from plates and pipes to tubes and structural shapes, this practice caters to various forms.
Key aspects covered by ASTM E164:
- Calibration: the standard mandates meticulous calibration procedures for ultrasonic testing equipment using reference blocks containing artificial flaws of known sizes and depths. This ensures accurate flaw detection and sizing.
- Examination techniques: it outlines specific techniques such as straight beam, angle beam, and dual-crystal methods, along with their respective advantages and limitations for different weld geometries.
- Evaluation of indications: the standard provides criteria for interpreting ultrasonic signals, classifying detected discontinuities, and determining their acceptability based on relevant codes, standards, or specifications.
- Documentation: ASTM E164 emphasizes comprehensive documentation of the entire ultrasonic testing process, including equipment settings, calibration data, examination results, and interpretations.
