“…The primary challenges in producing dissimilar weld joints of Al alloys and steel arise due to the difference in thermal conductivity, electrical conductivity and solid solubility, large variance in melting points chemical composition etc. [6][7][8][9].The dissimilar weld joints contribute many advantages such as low manufacturing cost, reduction of processing steps, production of controlled low weight to high strength ratio objects, high fuel efficiency etc. [10][11][12] They also have few disadvantages such as formation of brittle intermetallic phases, precipitates, welding defects etc.…”

The current study investigated the effect of intermetallic formation on the corrosion behavior of dissimilar alloy welds of Al 5052 and Galvanized mild steel.Al 5052 alloy and galvanized mild steel plates welded in the form of lap joint by Cold Metal Transfer (CMT) welding process and Pulsed Arc Metal Inert Gas (PAMIG) welding process using 4043 Aluminumalloy filler. Welding conducted at different welding parameters viz., welding speed (0.8 m/min and 1.0 m/min) and wire feed rate (5.5 m/min and 6.5 m/min). The microstructure and phase determination of the weld joints analyzed by Field Emission Scanning electron microscopy and X-Ray Diffraction respectively. Resistance of galvanic, crevice and intergranular corrosion of the welds were studied as a function of different welding parameters as per ASTMG67-Al-alloys. The effect of welding parameters on the corrosion resistance of the joints and correlation of microstructural features such as formation of intermetallics at the interfaces etc. throughout specimens studied in detail.
