In the process of boiler manufacturing,installation and inspection,the ultrasonic phased array inspection technology can generally be used to effectively inspect the welds of complex structures,and the selection of the inspection process has a great impact on the inspection results.For specific workpiece and process,combining CIVA simulation can quickly analyze the imaging effect,which is of great significance for process optimization.In this paper,CIVA software is used to implement phased-array testing simulation of defective holes in specific areas of phased-array A-type test block.At the same time,the same process is used to carry out actual phased-array testing,and the positioning and quantitative accu-racy of each flaw hole is compared and analyzed.The results show that the difference between CIVA simulation and actual testing results is small,and the actual testing accuracy is slightly better than CIVA simulation.
