In this article, an innovative new method of non-destructive testing for estimating the sensitivity of limestone is presented. An advantage of the laser ultrasonic structuroscopy method is the time and the quality, due to which less tests are necessary for an analysis of rock properties. Limestone is measured with an innovative structural control method, which shows a good qualitative and quantitative agreement with the basic structural analysis.

The presented research contains a description of a non-destructive laser ultrasound internal structure analysis of aluminium joints made by friction stir welding. In the research, four selected technological parameter groups were taken into account. Modifications used in different parameter groups included changing tool traverse speeds and also its rotation speeds. The most important goal of this research was to determine the joint quality using a non-destructive laser amplified ultrasound method To verify obtained test results, an additional microstructural analysis was also conducted.
