Latest Patents

One of Ishikawa's latest patents is a friction stir welding tool designed for working with metal materials and structures. This innovative process involves performing friction stir welding while supplying a filler into the joining portion. This method prevents the coarsening of crystal grains in metal materials during subsequent fusion processing. Following the friction stir welding, a fusion process such as MIG welding is executed. The filler used in this process is a substance that does not chemically react with the metal materials and has a melting point higher than that of the metal materials. Additionally, the filler must have a misfit with the metal materials within ±15%. This innovative approach inhibits the coarsening of crystal grains during fusion processing, ultimately increasing joint strength.
