  • Weld metal material apparatus and method
    Patent number: 7721937
    Abstract: A solid weld-metal-producing material is formed by agglomerating weld metal material powder. An igniter may be integrally formed in or on the agglomerated weld metal material. In addition to typical components of a weld metal material mixture, such as a reductant metal and a transition metal oxide, the agglomerated weld metal mixture may include a binder material, such as sodium silicate. In addition to functioning as a binder to help hold the agglomerated weld metal material together, the binder material may aid in the exothermic reaction that occurs when the weld metal material is ignited. The agglomerated weld metal material may be made by mixing together a reductant metal powder, a transition metal oxide powder, and possibly a binder solution. A slurry of the components may be pressed together, for example, using a die and a ram, and then may be dried.
