|
Answer» MT:- Only Applicable for ferromagnetic MATERIALS & able to detect both SURFACE & sub surface discontinuities, compare to PT examination it takes less TIME for testing & INSPECTION; Applicable for large temp RANGE. PT:- Applicable for both ferromagnetic & non ferromagnetic materials & able t detect only surface discontinuities, It requires more time; Applicable for small temp range.
