Globally, aluminium and its alloys are generally regarded as materials that are difficult to weld. Research is ongoing with a view to finding newer and better ways to repair or weld these alloys. Consequently various mathematical models are currently being adapted to formulate new compositions for aluminium welding fluxes. In this study, a new flux was developed for the welding of high strength aluminium alloy using the Gauss Jordan Row Operation model. By applying this model, an optimum composition of 39% NaCl , 20.5% CaCl2 , 20.5% KCl, 6% CaF2, and 14% 3NaFAlF3, was obtained. The weldment which resulted from the application of this optimum flux was subjected to certain mechanical tests, such as the tensile test, hardness test, and micro-structural analysis. The ultimate tensile strength of the weld was found to be 428 MPa, 0.2% proof stress of 305 MPa, and a Brinell hardness number of 94. These values compare well with published values in literature. Also from the micro-structural analysis, the weld is confirmed to be of good quality. A systematic (step by step) approach has been applied in this research work and found to be very rewarding.
