Abstract
How to detect and control the quality of resistance spot welding joints has become an urgent problem to be solved.Ultrasonic detection method is widely used in the quality evaluation process of resistance spot welding joints because it can intuitively display the size of joint core and the position and size of defects through waveform characteristics and images.In this paper,wavelet transform and gray level homogenization technology are introduced to reduce noise and enhance image,so as to extract image features of solder core more accurately.Meanwhile,a prediction model of solder core shape and quality prediction is established by using artificial intelligence technology.The results show that the measurement accuracy of the diameter of molten core is more than 90％,which is consistent with the actual diameter of molten core measured by metallography.This method significantly reduces the cost of performing destructive tests and improves the reliability of evaluation.关键词
