What should be the focus of the inspector when flaws are detected during MPI?

When flaws are detected during Magnetic Particle Inspection (MPI), the primary focus of the inspector should be on interpreting the indications and determining their relevance to potential defects. This is crucial because the inspector must assess whether the indications observed are significant and may pose a risk to the integrity of the material or component being tested.

The process involves analyzing the size, shape, and location of the indications to ascertain if they represent actual defects that could affect performance or safety. This evaluation is essential for making informed decisions regarding the reliability and usability of the part in question.

Understanding the implications of the findings is vital in deciding the next steps, whether that involves further testing, repair, or rejection of the component. Effective communication of these assessments, along with accurate documentation of the inspection results, is critical for quality control and compliance with industry standards.

While other choices may involve aspects relevant to the inspection process, they do not directly address the inspector’s paramount responsibility of flaw evaluation and relevance determination, which is foundational in ensuring safe and effective use of components post-inspection.
