| Abstract: | The imaging characteristics of ultrasonic phased array(PAUT)and total focusing method(TFM)were summarized,giving agroup of displays of defects in welding samples as cases.Finally,in accordance of the comparative analysis consequence,it is suggested that PAUT should be used for the detection of full weld coverage and TFM should be used for the critical defect areas or the critical areas to improve the quantitative and characterization results of defects. |
