The low arc heat input welding process can reduce the amount of heat energy required to join the weld metals to produce the desired structures resulted in lower heat-affected zone width, good penetration depth and proper bead geometry formation.In this research, the cold metal transfer welding process was utilized Measuring Cup Sets to join the dissimilar plates of AA62082 and AA7075 base metals with ER2219 filler wire.Lower welding currents were used to join the 6 mm thick plate in single pass without any defects.The macro and bead properties were taken from the optical microscope along with their structural changes at various zones of weldment.
The standard tensile testing was carried out for three samples using universal testing machine.Cyclic sweep test was conducted on weld surface area to study the corrosion resistance VIRAFECT in alcoholic environment.The results obtained from this research work presented and discussed in detailed by comparing other welding technique.
