Abstract
Dependence of increase of the length of shock wave formed within the joining zone between titanium and steel in explosion welding on path length of the detonation wave has been studied. A simplified calculation model of the given process is suggested, based on an assumption that the key factor affecting increase in shock wave length is expansion of the gap between the plates located in parallel due to the impact on them of an air plug formed ahead of the contact point.
