ASTM E747 Radiographic Testing with Wire Image Quality Indicators
The ASTM E747 standard provides a method to perform radiographic testing using wire image quality indicators. This non-destructive evaluation (NDE) technique is essential for assessing the integrity of materials used in additive manufacturing (AM) and 3D printing processes, ensuring that fabricated parts meet stringent quality requirements.
In AM and 3D printing, the process involves layer-by-layer deposition of material to form a three-dimensional object. This intricate method can lead to unique challenges in terms of quality control and defect detection. ASTM E747 addresses these issues by providing a robust framework for ensuring that the materials used are free from defects that could compromise the final product's integrity.
The wire image quality indicators (WIQI) used in this testing provide standardized reference points to evaluate the radiographic images produced during the AM process. WIQI help determine the radiographic image quality and ensure consistency across different imaging systems, which is critical for accurate defect detection.
During ASTM E747 testing, a series of wire indicators are placed within the part being inspected. The part is then exposed to radiation, typically X-rays or gamma rays, creating an image that can be analyzed for defects and quality assurance. The use of WIQI ensures that the radiographic images produced meet specific acceptance criteria outlined in ASTM E747.
The testing process involves several steps:
- Placement of wire indicators within the part being inspected
- Exposure to radiation source
- Capture of radiographic image
- Evaluation and interpretation of the image by qualified personnel
This method is particularly useful for detecting internal defects, such as cracks, voids, and inclusions that might not be visible through other inspection methods. It provides a detailed view of the material structure, allowing for precise defect characterization.
ASTM E747 testing is widely used in industries where AM and 3D printing are employed, including aerospace, automotive, medical device manufacturing, and consumer goods production. Its application ensures that parts produced through these advanced manufacturing techniques meet stringent quality standards.
The ASTM E747 method is crucial for ensuring the reliability of materials used in AM processes. By providing a standardized approach to defect detection, it helps manufacturers comply with international standards and specifications, thereby enhancing product safety and performance.
