چکیده مقاله
The main aim of the present research is to calculate the reliability of non destructive tests NDTs and use its results for decreasing the number of DT’s bodies To this end, five car bodies were randomly selected from the production line Then, different types of tests including Ultrasonic test UT , Chisel test CT , and Peel test PT were performed on the critical groups of Resistance Spot Welding RSWs The experimental results were categorized based on the strength defects of RSW including good weld OK , stick weld ST , and undersize of nugget diameter IM Bernoulli probability approach was used to calculate the reliability of NDT methods The results indicated that the reliability of various techniques of NDT which are used in the automotive industry is more than 94% However, the ability of IM defect determination by UT is low
