L-statistical analysis of sound signal acquired from pulse mode laser welding for characterising weld geometry

Many ongoing studies have proven that statistical features extracted from the acquired sound during a laser welding process significantly yield some pictures on the weld condition, including weld geometry. However, a considerable amount of studies has underlined the use of common statistical feature...
