Abstract

An igniter for particulate weld metal material includes a resistor, and a pair of conductive leads connected to the resistor. The resistor is located in or above the weld metal material. An electrical current is provided to the resistor to overload the resistor and cause it to structurally break apart, such as by exploding, spewing hot resistor material into and/or on the weld metal material, igniting the weld metal material. Weld metal produced by the exothermic reaction of the weld metal material is used to weld together two or more pieces of metal, ends of metal bars, thereby electrically and/or mechanically joining the bars together. The igniter may be including in a weld metal package that includes the particulate weld metal material. The package may be a sealed package, with parts of the conductive leads protruding from the package.
