A series of laser joining experiments between polyethylene terephthalate (PET) and aluminium alloy (A5052) were conducted to investigate the effect of anodizing on A5052 surface on dissimilar materials used in joining. In this study, PET/A5052 joints with anodized A5052 surface exhibited greater shear strength compared to PET/A5052 joints without anodizing. The shear strength of the joints was ...

Friction stir welding is advance joining process for different similar and dissimilar metals. It is commonly used for joining of Aluminium alloys. In this study an attempt were made to join commercial structuralaluminium with 7039 aluminium alloy. A zig-zag pattern of hardness was found in weld nugget. Microstructural characterization and fractography of joints were examined using optical and s...

The effect of weld heat input on the formation of intermetallic compound (IMCs) layer during arc welding–brazing of aluminium and steel dissimilar alloys, was investigated through both finite element method (FEM) numerical simulations and experimental measurements. The results of FEM analysis as well as welding experiments indicated that increasing weld heat input increases the thickness of IMC...

Titanium and Zircaloy-4 dissimilar alloys were brazed with a zirconium-titanium-copper-nickel amorphous filler alloy, the resulting joint structures as well their corrosion properties examined. The microstructure of joints was investigated according to brazing holding time at 850 °C, property analyzed by potentiodynamic polarization. During brazing, produced diffusion-induced isothermal solidif...

The design of the dissimilar metal weld investigated here is aimed at applications in steam generator a sodium-cooled nuclear reactor, with multi-decade lifespan demanding operational conditions. It consists narrow-gap joint between 2.25Cr-1Mo low-alloy steel and an austenitic alloy using nickel-based 82 as filler material. This study focuses on understanding microstructural micromechanical evo...
