Which among the main ndt tests are more applicable?

Friends,

Regional projects of which NDT was an important part. Through these ... Among these, ... even in the most sophisticated of industries, including the nuclear and aerospace industries. The ...... Standards applicable i Think liquid penetrant testing.

EVERY TEST HAS THERE OWN IMPORTANCE. 

eg:

PT: is good for surface defect.

RT: is good for volumetric  type defect.

UT: is good for planar type defect.

LPT is comonly used in all types of weld joint and pipes because it is easy to use and fast result, RT is widely used in small bore and UT is for large bore.

the X-ray test that is the most applicable method in the industry

THE STANDARD ONE IS VISUAL TESTING .THE VERY FIRST STEP TO BE FOLLOWED IN EVERY NDT TESTING IS VT

Liquid Penetrant test,Radiography test

The more applicable NDT test is RADIOGRAPHY TEST. But each tests have its on merits and demerits.

PT,MT,RT,UT

These method are normally use to check the weld soundness

PENETRANT TEST ,DUE TO TO ITS EASY OF ACCESS ,LOW COST,AND MOST OF THE WELD ARE REQUIRED ONLY TO BE CRACK PROOF AS FITNESS FOR PURPOSE  APPROACH,AND LPT IS VERY USEFUL IN DETECTING SURFACE CRACKS BY LOWEST OR NO AMOUNT OF SKILL.

Visual inspection is the most applicable test , because its faster, needs no complicated equipment and less in cost

in algeria the ultrasonic is the most test used in the CND
