Different Methods of NDE
Each method of Non Destructitve Examination (NDE) of welds has its strengths and its weaknesses in determining specific features of a material.
MT and PT are used for detecting surface flaws. MT relies on a magnetic field and steel particles; an indication or discontinuity in the weld allows the magnetic flux to leak, attracting the particles. PT uses a liquid penetrant that is applied to the weld, then removed; a developer draws any remaining penetrant out of any openings, making small cracks, holes or crevices easily visible.
RT and UT are volumetric tests. RT uses Gamma or X-rays to create a sharp, detailed 3-D image of a weld joint and HAZ on a film, whereas UT and PAUT uses sound waves to find discontinuities in the weld.
Visual Testing (VT) which is the primary and all-encompassing form of welding inspection along with the inspector’s knowledge and observations of the welding process, welding environment, material selection, condition, preparation, fit up, tacking, interpass and weld finishing will usually determine if a weld is sound or acceptable. The NDE methods listed above are used along with VT to determine weld soundness and Quality acceptance
