In order to reapply the waste energetic materials as welding heat source, in this article, the energy densities of several types of gunpowder were calculated with the equation of energy density. The results show that the energy densities of powders are very low, which are impossible to weld metal. Otherwise, the effects of aluminium powder and thermite on the energy density of gunpowder were investigated,...
In this article, the combustion properties of several types of propellants and configuration of welding rod have been researched. The results show that it is feasible that reapplication of waste propellants as welding heat source, for which 171-25 propellant is the best suitable.
