Abstract: Rolled Homogeneous Armour (RHA) steel is known as protective steel and it is utilized in a military vehicle, For example tanks, howitzers, heavily clad battle vehicles just as developments in armament. Weld quality straight forwardly decides the entire mechanical properties of the protective steel in vehicle body structures. Hybrid Optical Maser Arc welding (HOMAW) has a decent mechanical property and focal point of this exploration is considered to recover more energy than laser and Metal Active Gas Welding (MAGW) process. Manual Metal Arc Welding (MMAW) with low hydrogen ferritic filler (LHF) which performs better weldability on Armour steels with comparing MMAW with Austenitic stainless steel (ASS), and Flux cored arc welding (FCAW) with ASS/LHF. MMAW procedure is considered to reduce the expense through LHF consumable in workplace. The examination of MAGW method, a welding fringe of 54o V-narrow cut geometry has better mechanical property for tensile strength and also the welding narrow cut point of 48o X-trench cut geometry has better solution for compression strength of butt-joint Armour steel. This survey was embraced to grant a top-level view of the various categories of welding process and mechanical properties in welding of RHA steels.
