People seem to have created a tool for every purpose. If a person searches diligently, he can usually find the tool he needs. However, several things may affect this process such as time, cost of the tool, and limited tool sources. The solution to all these is to make the tool yourself. People ...

Friction stir spot welds were made in two high-strength steels: DP780, and a hot-stamp-boron steel with tensile strength of 1500 MPa. The spot welds were made at either 800 or 1600 rpm using either of two polycrystalline boron nitride tools. One stir tool, BN77, had the relatively common ...
