Visual testing is basically used for determination of things which include surface condition of part, reinforcement and undercutting of welds. 3 methods are employed by experts. One is direct visual examination, second is remote visual examination and last is translucent visual examination. This testing basically requires several methods. It is part of NDT examination. It has several benefits which include simplicity, rapidity, low cost, minimal training and equipment requirement.

Liquid penetrant testing can be applied to any non-porous clean material, metallic or non-metallic, but is unsuitable for dirty or very rough surfaces. Surface cleaning is a vital part of the penetrant testing technique. The method can be manual, semi-automatic or fully automated. Penetrant inspection, continuous-operation production lines in which the specimens are cleaned, dipped, washed, dried, etc. on a time cycle are common.

Magnetic particle testing is a non-destructive testing way for locating near surface discontinuities in ferromagnetic materials. It depends for its operation on the fact that when the part under test is magnetized, discontinuities that lie in a cause leakage field to the direction of the magnetic field will cause a leakage field to be formed at and above the surface of the part.

Ultrasonic Testing is basically used for flaw detection and evaluation, dimensional measurement, material characterization and others. This method requires lot of training and operator should have full-fledged knowledge for interpretation of result. This testing is highly useful and an effective method.

Radiographic Testing (RT) is a nondestructive examination (NDE) technique that involves the use of either x-rays or gamma rays to view the internal structure of a component. In the petrochemical industry, RT is often used to inspect machinery, such as pressure vessels and valves, to detect for flaws.

Phased array ultrasonic (PA) is an advanced method of ultrasonic testing that has applications in medical imaging and industrial nondestructive testing. Common applications are to noninvasively examine the heart or to find flaws in manufactured materials such as welds. Single-element (non-phased array) probes, known technically as monolithic probes, emit a beam in a fixed direction.

Time-of-flight diffraction (TOFD) method of ultrasonic testing is a sensitive and accurate method for the nondestructive testing of welds for defects. TOFD originated from tip diffraction techniques which were first published by Silk and Liddington in 1975 which paved the way for TOFD. Later works on this technique are given in a number of sources which include Harumi et al. (1989), Avioli et al. (1991), and Bray and Stanley (1997).
