A newly developed Non-Explosive Technology (NEXT) produces ultra-high pressure hydrogen. This technology has been applied in the development of welding (impact bonding) similar and dissimilar metals, whereby a projectile material is launched into a stationary material. Specific impact conditions form a superior cold weld with no heat-effected zone, thus preventing degradation of the material properties of each of the joined materials. A variety of materials that previously could not be joined through conventional welding methods have been achieved through NEXT with funding provided by the NSF. North Carolina State University has verified and quantified that the bonded test materials have symmetrical wave morphology and a hermetically sealed transition, exhibiting superior strength – greater than that of the materials being bonded. Unlike traditional Explosive Welding (EXW) used to bond dissimilar metals, NEXT is portable, allowing near-net shaped and net-shaped parts to be bonded directly to one another or onto large fixed objects. Additionally, the welded joint prevents galvanic corrosion and electrical arcing between sensitive electronic components. Due to eliminating the shockwaves associated with explosives, AHPT is exploring the joining of ceramics and carbides to steel. The research has led to the discovery of the propulsion characteristics that may achieve vast improvements over conventional gun powders for small and large munitions as well as testing devices.
