TL;DR: In this paper, high speed photography is used to study the dynamics of bulge formation, spark growth, and projectile illumination during primary and secondary impact of flat-ended projectiles, and it is suggested that fragmentation of the spark is due to inter-metallic jetting.

TL;DR: The results of an investigation on weld interfaces of impact-welded dissimilar metal combinations are presented in this paper, showing that welded interfaces generally comprise wavy and plane zones areas adjacent to waves contain hardened and plastically deformed regions.

TL;DR: In this article, a photogrammetric measuring technique was used to determine the final profiles of polymeric cylindrical projectiles, at speeds ranging from 100 to 600 m/s, in connection with metal sheet deformation during impact spot welding.

TL;DR: Impact welding is a practical and economically feasible process for the solid-phase welding of similar and dissimilar metals as mentioned in this paper, which can be brought about by the action of a high-velocity object such as a projectile on the material comprising the impacting object-target interface.

TL;DR: In this paper, the weld interface between copper flyer plates and brass parent plates that are impact spot welded by the use of LDPE projectiles of various nose shapes was investigated, and cases involving entrapped air and jetting were observed.
