A high-space-resolution image-intensifier camera with luminance gain of up to 5000 and exposure times as short as 30 ns has been applied to the study of the interaction of posts and welds with strongly shocked metal surfaces, which included super strong steels. The time evolution of a single experiment can be recorded by multiple pulsing of the camera. Phenomena that remain coherent for relatively long durations have been observed. An important feature of the hydrodynamic flow resulting from post-plate interactions is the creation of a wave that propagates outward on the plate; the flow blocks the explosive product gases from escaping through the plate for greater than 10 ..mu..s. Electron beam welds were ineffective in blocking product gases from escaping for even short periods of time.
