摘要： 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.

摘要： An exothermal weld mold includes a mold section with an integral cover portion, made as part of a single piece of material with the rest of the mold section. The mold section may be a mold half of a vertically split mold, or may constitute most of a half of the mold. The cover portion may be part of an integral cover that covers substantially all of a reaction chamber or crucible of the mold. The cover may have one or more vent holes, in the top and/or side of the mold. The cover may have a baffled passage for expansion of gases produced by reaction of the weld material, before the gases are expelled from the mold at an opening in the top or side of the mold. The passage may be a serpentine passage. A filter may be placed in the passage.
