In liquid penetrant testing (LPT) method, preparation of testing surface is very critical.

In liquid penetrant testing (LPT) method, preparation of testing surface is very critical. Correct Answer True

For the use of penetrant inspection, proper preparation of the test surface is critical because unprepared surface will only reveal gross porosity and large cracks on the surface. So for preparing the surface for testing, process like machining, caustic etching, acid pickling etc. are used.
