Abstract


Evaluating the protection level of armored materials used in vehicles is NOT sufficient in ensuring that the vehicle provides full protection against assigned threats. This is due to the fact that the design of any vehicle includes joints, overlaps, welds, bolts, etc.… that was proven buy extensive experiments to have significantly less protection capabilities compared to the main structure of the vehicle. This study focused on the Heat affected zones HAZ is particular associated with welding armored plates. In welded armored plates, the extensive heat creates an area referred to as the "Heat Affected Zones HAZ" that has significantly less ballistic protection capabilities due to the change in their microstructure, the size of the grains and their distribution and many other factors. The aim of this work was to investigate the effectivity of potential solutions implemented to overcome the reduction in the ballistic protection of the Structural Weak Areas (SWAs) from a test and evaluation point of view. Solutions investigated in this study included; Increasing the thickness of the base material reducing the heat affected zone’s size and severity, replacing the conventional welding techniques with sand blasting, gluing and ballistic coating and finally special Multi-layer overlapping techniques as a solution most suitable in Corner Joint welds. All three potential solutions have showed success in resisting the assigned threat but each with its limitations such as; increased effort, cost and weight which determine the selection of one solution technique over the other.
