Abstract
Radiography, Ultrasonic, Magnetic Particle, Liquid Penetration and Visual Inspection tests are the common Non-destructive testing techniques that are used to test the weld joints. In this research article an introduction about the need for various (NDT) Non-Destructive Testing techniques and the methods of evaluation adopted for weld joints which can be used for various applications like shipping, construction, railway industries, etc are briefly discussed. This research work emphasizes the NDT techniques pertaining to inspect low carbon steel weld joints. Case studies related to various defects in welding are also discussed. This research is an attempt to find the sensitivity on various (NDT) Non-Destructive Testing techniques to detect the welding defects.
