The course aims to provide the basic know-how of the Non-Destructive Testing (NDT) to be carried out on mechanical devices or their individual components during construction or operation. The presence of discontinuities and defects generated during the foundry, casting, welding processes or during the service life of the mechanical elements will be analyzed. The student engineer will be instructed on the most significant aspects of non-destructive testing methods ranging from visual inspection to the most refined radioscopic methods. The course also includes laboratory exercises with examples of the use of some of the most common methods.
The first phase of the course includes an introduction on the defects generated during the processing processes in the furnace, casting, cold or hot plastic processing of metal elements. Defects produced during various welding methods, during mechanical processing or during the useful life of mechanical elements will be analyzed. The main test methods for identifying the defects described without breaking the element under examination are then studied. During the course, classroom or laboratory exercises will be carried out.
Description of the defects generated during the processing processes in the furnace, casting, cold or hot plastic processing of metal elements. Description of defects produced during various welding methods, during mechanical processing or during the operation of mechanical elements. Analysis of the following non-destructive test methods for identifying defects: Visual investigation, Penetrant liquids, Magnetoscopy, Acoustic emission, Thermography, Eddy currents, Radiography, Ultrasound and Leak detection.
