Digital Defect Metrology
Digital defect metrology is a precise measurement technique that captures crack lengths, pore volumes, and wall thicknesses from 3D data or ultrasound images.
Physical-Chemical Mechanism of Action
Digital defect metrology uses digital images and 3D reconstructions to analyze microscopic structures. Software is used that identifies and quantifies specific defects in the images.
Metallurgical Relevance & Welding Risks
This technique enables detailed analysis of weld quality. It helps in detecting hidden cracks, pores, and other defects that are not visually apparent. Misinterpretation or technical issues with the measurement can lead to inaccurate results, which in turn leads to wrong decisions in quality assurance.
Workshop Practice & Operating Instructions
Applying digital defect metrology requires special software and hardware. The images must be carefully taken and the software correctly calibrated. It is important that the technician knows the software well and knows how to interpret the data. Recommended steps are:
1. Use high-resolution ultrasonic devices or 3D-CT scanners.
2. Calibrate the measurement before each run.
3. Thoroughly review the results and compare them with standards.
