Study on Weld Defects in Aluminium 2014 T6 Alloy using Liquid Penetrant Testing and Correlating with Radiography Films

Non-destructive testing is a different kind of tests which are used to learn about the physical properties of specimens. By the other techniques like tensile testing and hardness testing the specimen is destructed after the experiment but in this testing type the specimen is not destructed. There are eight different NDT methods: Visual Inspection, Microscopy, Radiography, Dye penetrate, Ultrasonic, Magnetic Particle, Eddy Current and Acoustic Emission. These methods are only separated in application technique. We used two different types of methods for our testing, Liquid penetration test and Magnetic particle testing. Non-destructive Testing is one part of the function of Quality Control and is Complementary to other long established methods. By definition non-destructive testing is the testing of materials, for surface or internal flaws or metallurgical condition, without interfering in any way with the integrity of the material or its suitability for service.
