Introduction

Non-destructive testing (NDT) is a group of techniques used to inspect materials, components, or systems without damaging them. NDT is used to detect flaws like corrosion, fractures, and voids that could affect the structural integrity or operation of a system.

VISUAL INSPECTION (VT)

Visual Inspection (VI) is a fundamental non-destructive testing (NDT) method that involves examining the surface of a material or component for defects using the human eye or optical instruments. Vt can be applied everywhere, including object with elevated temperature. Potential users are weld workshops and assembly workplaces.

DYE PENETRANT TEST (DPT)

It also called liquid penetrate inspection (LPI) or penetrant testing (PT), is a widely applied and low-cost inspection method used to check surface-breaking defects in all non-porous materials (metals, plastics, or ceramics). The penetrant may be applied to all non-ferrous materials and ferrous materials, although for ferrous components magnetic-particle inspection is often used instead for its subsurface detection capability.

Dye penetrant test is quite inexpensive as compared to other non-destructive methods viz. Mt, ut, rt, and et, etc.
Dpt is very sensitive and small discontinuities can also be detected easily.
This test consumes very little time; hence material could be inspected rapidly.
Mcomplex geometric shapes can also be inspected with ease.
One of the major advantages of the dye penetrant test (dpt) is its portability.

Magnetic Particle Inspection (MPI)

Magnetic Particle Inspection (MPI) is a non-destructive testing (NDT) method used to detect surface and near-surface defects in ferromagnetic materials, such as iron, nickel, cobalt, and their alloys.

It is quick and relatively uncomplicated.
It gives immediate indications of defects.
It shows surface and near surface defects, and these are the most serious ones as they concentrate stresses.
The method can be adapted for site or workshop use.
It is inexpensive compared to radiography.

Ultrasonic Test (UT)

Ultrasonic Testing (UT) is a non-destructive testing (NDT) method that uses high-frequency sound waves to detect internal flaws or characterize materials.

It Is Quick And Relatively Uncomplicated.
It Gives Immediate Indications Of Defects.
It Shows Surface And Near Surface Defects, And These Are The Most Serious Ones As They Concentrate Stresses.
The Method Can Be Adapted For Site Or Workshop Use.
It Is Inexpensive Compared To Radiography.
