Friction Stir Welding Tool Materials

The steel FSW with a higher melting point has been considered difficult for use as a joining tool because the tip of the tool becomes excessively hot due to frictional heat, severely damaging the tool. By applying a ceramic coating that has excellent wear resistance to a low cost tungsten alloy that does not use expensive elements, we have provided the following characteristics to the tool. Our goal is to achieve price lower than conventional tool currently considered to be the most reasonable, while achieving higher durability and longer service life than the conventional low cost tool materials.
