Fully automated Magnetic particle testing of Liner Components using Automatic Defect Recognition (ADR) algorithm

Dhvani R&D developed an Automatic Defect Recognition (ADR), a software algorithm to detect the defects automatically with out human interference. This algorithm is integrated with Magnetic Particle inspection system for a fully automatic and seamless inspection process.

Seamless Inspection Procedure

System Details

The complete system consists of

  • 1. Magnetic particle inspection system with rotary arrangement for rotating the sample.
  • 2. Camera unit system for taking the images of the sample.
  • 3. Computer system with ADR image processing tool for automatic defect identification and sizing.

System Descripion

  • 1. The samples are placed on the rotary table arranged at the MPI station.
  • 2. MPI solution is applied and the samples is set to rotate.
  • 3. The camera system takes the images of the sample while rotating.
  • 4. The captured images will be processed by the ADR algorithm to identify defects.
  • 5. System gives an alarm as per accept/ rejection criteria.
  • 6. Mapping of defects on the samples for visualization in post processing.
