Abstract

The welding penetration depth and width measured by destructive inspection are very important items to evaluate welding quality. However, the destructive method has some limitations and disadvantages. In this study, ultrasonic measurement technique which can make the image of cross sectional macro structure non-destructively was investigated. As a result, it is concluded that signal processing of ultrasonic back scattering is effective to measure the penetration depth of welds.
