At present, the automotive industry mainly through the process monitoring based on coating specifications, as well as the result monitoring based on the final bonding effect to effectively ensure the quality of the coating. In order to improve coating quality detection efficiency, this paper, by learning from to the ultrasonic welding spot nondestructive testing technology, explores the application of ultrasonic phased array technology in the detection of body glue, and proves its feasibility theoretically, Moreover, this paper also uses ultrasonic phased array nondestructive testing instrument for practical application inspection, and finally realizes the nondestructive testing of body glue.
