Liquid Penetrant Test is a method that is used to reveal surface breaking flaws by bleed out of a colored or fluorescent dye from the flaw..
Eddy current Test
Eddy current inspection is one of several NDT methods that use the principal of electromagnetism as the basis for conducting examinations.
Radiographic Film Interpretation
In addition to producing high quality radiographs, the radiographer must also be skilled in radiographic interpretation.
Interpretation of radiographs takes place in three basic steps ;
Visual inspection relies upon the detection of surface imperfections using the eye. It is nrmally applied without the use of any additional equipment, however VT can be improved by using aids such as magnifying glasses, mirrors, or borescopes/videoscopes to gain access and closer inspection of the subjected area to improve its effectiveness.
with this visual test, the following work can be done:
