Performing multiple passes on these mock-ups to collect ultrasonic data.

Comparing the AUT results against the actual "true" size of the seeded flaws (often verified later by macro-sectioning the weld). dnv-rp-f118

Because physical qualification is time-consuming and expensive, industry professionals often use simulation tools like CIVA NDT Software to augment the process. Simulation can: Predict probe coverage and beam behavior. Help design calibration blocks. Performing multiple passes on these mock-ups to collect

The primary goal of a qualification process under DNV-RP-F118 is to establish a Probability of Detection (PoD) curve. This curve is a statistical representation of the system's effectiveness. Simulation can: Predict probe coverage and beam behavior

DNV-RP-F118, often cited alongside the offshore service specification , outlines the requirements for demonstrating that an AUT system can reliably detect and accurately size flaws in pipeline girth welds. Traditional radiography (RT) has largely been replaced by AUT in modern pipeline projects due to the latter's speed, safety, and ability to provide three-dimensional data on weld defects. The Core Objective: Probability of Detection (PoD)

DNV-RP-F118 emphasizes that a small number of samples (like 3 or 4) is insufficient to prove reliability.
