Friction stir welding (FSW) is a newly developed welding technology for welding of soft alloys. This is a solid state welding process in which the work material which is to be welded does not get melt and a joint can be easily obtained without the use of some additional filler material, gas protection or any other precaution. A hard rotating tool with a profile pin/probe and a shoulder gets inserted into the joint line and with the help of suitable transverse weld feed with some axially downward pressure the weld can be produced. Here the effect of three transverse weld feeds of FSW welding of AA6061 keeping rotational speed and axial pressure constant, were examined on the basis of weld microstructure and tensile properties. It was found that the microstructure of AA6061 is fine for low transverse weld feed as comparison to the other transverse feeds and on this transverse feed the tensile properties of the weld metal is higher than that of other two welding transverse feeds.

An analysis was performed on potential materials that could replace the 6061-T6 aluminum alloy currently used in the AM2 airfield matting for the purpose of light-weighting the design. An in-depth analysis was performed on metal and polymer matrix composites. However, neither groups of materials produced a suitable material based on operating conditions of the AM2. Newly developed extruded magnesium alloys were identified that could potentially provide weight savings of 30 to 40% while maintaining the current performance of the AM2. In addition, traditional high-strength aluminum alloys were identified that could provide substantial weight savings. However, manufacturing issues existed due to the high strength of these aluminum alloys. Finally, analysis was performed to determine the cost of manufacturing the AM2 using these alternate materials.

AA2519-T87 aluminium alloy is newly developed armour grade, age hardenable alloy with best mechanical properties, high impact toughness and ballistic resistance properties Because of this beneficial property it is preferable in replacement of steels in the light combat vehicles in order to reduce the weight and improves mobility. Formation of oxide layers, solidification cracking and porosity creates problems in the fusion welding of aluminium alloys. Gas tungsten arc welding (GTAW) is widely used fusion welding process for joining aluminium alloys which results improved arc stability, reduced thermal distortion, reduced residual stress and spatter free joints. By proper controlling of process parameters of GTAW, sound weld joint is achieved at welding current of 145 A, welding speed of 2 mm/s, and voltage of 16 V. Due to heating and rapid cooling cycles, the weld joints properties deteriorated due to loss of
