Magnetic Particle Testing (MPT) is a type of Non-Destructive Testing (NDT) where we examine the test piece or job using the application of electromagnets to identify surface defects.
Testing Process
- We use an electromagnetic machine for testing.
- Metal powder (usually magnetic) is required during the inspection process.
- The metal powder is sprinkled over the inspection area while the electromagnetic machine is turned on.
- The powder accumulates around defect areas on the surface, making them visible for rectification and rechecking.
