What working principle of MPI and Auto UT and Manual UT m/c and final inspection line where gauge yor are used????

Question

Accepted Answer

MPI, Auto UT, Manual UT, and final inspection line are used for non-destructive testing in manufacturing.

MPI (Magnetic Particle Inspection) uses magnetic fields and iron particles to detect surface and slightly subsurface defects in ferromagnetic materials.
Auto UT (Ultrasonic Testing) uses high-frequency sound waves to detect internal defects in materials.
Manual UT (Ultrasonic Testing) is similar to Auto UT but is performed manually by an operator.
Final inspection line is where the finished product is inspected for defects before it is shipped to the customer.
Gauges are used to measure various parameters such as dimensions, tolerances, and surface finish.
