A new sampling inspection system of NDT has been proposed to secure the quality of welds of steel buildings. In this system, the quality of welds is evaluated based on reliability-analysis in which probabilistic parameters such as detectability of NDT, sampling rate are considered. In the present new system, the whole processes of welding works are divided into a certain number of steps, and then, the reliability of every step is calculated by using the inspection data of that step. And the inspection plan is modified at any next step if necessary so that the average reliability of all welds will conform to satisfy the reliability requirement which was already given by the structural designer. In the present paper, the new system is termed "Step Inspection System". The availability of Step Inspection System to secure the required reliability of welds was confirmed by applying actually to the 40-storied and 27-storied steel buildings.
