Exposure time calculation in RT
Exposure time calculation in RT is very important to perform radiography tests and develop radiographs meeting the standard requirements. Exposure time is the time required for sufficient radiation energy to ionize …
UT – Key formulas
UT – Ultrasonic testing is used to test a variety of both metallic and nonmetallic products, such as welds, forgings, castings, sheets, tubing, plastics (both fiber-reinforced and unreinforced), and ceramics. …
Nondestructive Inspection of Forgings
Since the Industrial Revolution, forged parts are widely used in mechanisms and machines wherever a component requires high strength. Forging can produce a piece that is stronger than an equivalent …
Magnetization Techniques in MT
Magnetic particle testing is used to detect surface and shallow subsurface discontinuities such as cracks, laps, seams, cold shuts, and laminations in ferromagnetic materials (no other type of material) such …
PT – Preparation & Precleaning of Test Objects
In PT- Preparation & Pre-cleaning of Test Objects is an important step in the test process because only when penetrant is placed on a clean, dry surface will wet the …
Mechanical properties of metals
Mechanical properties are physical properties that a material(metal) exhibits upon the application of forces. The mechanical properties of metals determine the range of usefulness of the material and establish the service life that …
PMI
If a material certificate of purchased material is missing or it is not clear what the composition of a material is, then PMI offers the solution. Moreover, The most frequent …
Radiographic Film Processing
Radiographic Film processing refers to a series of steps to convert the latent image (invisible) on the film into a visible image. X-ray films for industrial radiography consist of an emulsion and a …
PCN certification
PCN – Personnel Certification in Non-Destructive Testing – is a scheme for the certification of competence of non-destructive testing operators. Certification is given for the traditional NDT methods and has …
UT Immersion Testing
UT Immersion testing techniques are mainly used in the laboratory and for large installations doing automatic ultrasonic testing. It has the advantage that uniform couplant conditions are obtained and longitudinal …
