Nondestructive Testing service providers

  Non Destructive Testing,NDT on Shafts is considered essential , because the shafts are mostly made as load bearing structures, any defects such as cracks will propagate more during acting of load and eventually will cause failure. The most possible defects in shafts are Cracks and Pipes , which is shown below The Non Destructive methods preferred for defect detection on raw material shafts are Ultrasonic Testing, Magnetic Particle testing / Eddy Current Testing / Magnetic Flux Leakage method. We have not discussed about other NDT methods such as Liquid Penetrant testing & Radiographic testing because for raw material inspection. These methods will be cost effective for raw material testing  ( i.e. most costly and labor intensive, also there is possibility of missing out the cracks in radiography testing due to orientation of crack ) The Defect wise identification method is given as below  , Internal Defect ( Piping ) – Ultrasonic Testing Surface Defects  (C rac...

  NDT Method Selection: The NDT (nondestructive testing) methods are:   Visual Inspection – VT Liquid Penetrant Testing – LT Magnetic Particle Testing – MT Radiographic Testing – RT Ultrasonic Testing – UT Eddy Current Testing – ET (not used in field inspection) Acoustic Emission Testing – AET (not used in field inspection) Phased Array Ultrasonics – PA Time Of Flight Diffraction  –  TOFD Since each NDT methods has its own set of advantages and disadvantages and some are better suited than others for a particular application, the NDT technician or engineer  must select the method  that will detect the defect or make the measurement with the  highest sensitivity and reliability . The cost effectiveness of the technique must also be taken into consideration. The following table provides some  guidance  in the selection of NDT methods for common flaw detection and measurement applications. AQC (Advanced Quality Centre) is an ISO 9001:2015 certif...
