The Influence of the Tool Geometry on the Quality of the Weld in FSW Process - Friction Stir Welding. Firstly, using the FSW procedure, straight-line compounds were obtained, and soon afterwards also curvilinear, including circular. In addition to the great interest in the FSW process, many aspects of this process have not been sufficiently explored. This applies, inter ali

Science of Metals Through Lens of Microscope16th century, Dutchman Janssen made the first ever-increasing instrument. Robert Hooke was first used to illuminate objects using artificial light and gave a first description of plant cells still afar 1665. Henry Clifton Sorby, in the 1960s, was the first to apply a microscope in metal testing. Tod
