Abstract

The reliable of inspection and measurements in a non-destructive way is quite important in industrial area, mainly when it is related to quality control of weld joints. Ultrasound and Radiography can be used in order to check weld integrity. However they just can often be identified by visual inspection. 3D x-ray microtomography permits a real time quantitative investigation all over the micro architectural of the sample with a very good spatial resolution (micro order). The porosity parameter can be very important because it is related to the properties of alloy interconnects, such as degradation of mechanical performance. The goal of this work is to investigate critical welding flaws such as longitudinal, sagittal and transversal cracks, lack of penetration and porosity by 3D x-ray microtomography.
