Effect of Process Parameters on TIG Weld-Brazing of Aluminum Alloy to Galvanized SteelBy Krishna P. Yagati, Shibin A V, Jobin Joseph, Pablo S Ezhuparayil, Sherin Thampi, Tony Chacko
Abstract: AbstractAbility to join aluminum alloy to steel enables weight reduction of automobile bodies. Gas tungsten arc welding (GTAW) process was employed to weld-braze A8011-H14 aluminum alloy to galvanized steel in lap configuration. The influence of heat input on bead formation and joint strength was investigated. The microstructural characterization was carried out using an optical microscope and scanning electron microscope. The chemical composition was analyzed using energy dispersive spectroscopy technique. The …

Dissimilar Joining Of Aluminium Alloy to Copper Using Tungsten Inert Gas Welding ProcessBy Krishna P. Yagati, Naina Elizabeth Sebastian, Anjana Venu, Tom Jose Jose, Tony Saji, Sherin Thampi
Abstract: Aluminium-copper dissimilar joints are applicable to electrical industry. 2 mm thick aluminium alloys (A1100) sheet is joined to 1 mm thick copper (Cu-DHP) sheet using tungsten inert gas welding (TIG) process. The effect of process parameters like heat input, torch orientation, arc weaving on mechanical properties of the joint are studied. In this combination the molten pool generated by melting of aluminium edge will wet the coppersurface to form a …
