Abstract Welding of dissimilar metals is one the most substantial requirements industries and extensively used in engineering applications. Dissimilar friction crush welding between oxygen-free copper (C1020) aluminum (1145-H1) sheets with a thickness 1 mm was investigated this work using different flange edge heights (2, 2.5 3 mm) gaps (0.5 Cu-Al sheets. Tool rotational speed 1500 rpm feed rat...

Dissimilar Welding of Austenitic and Martensitic Stainless Steel Joints are commonly preferred in Nuclear Reactors where high temperature applications needed. There has been a huge demand for materials which sustain corrosive environment with rupture strength along pressure. These can be directly replaced the traditional nickel based alloys to compensate cost cutting satisfy requirements. weldi...

Electron beam welding has shown a remarkable job in the space industry for welding of components. It is performed under a vacuum environment that eliminates foreign matter such as hydrogen, oxygen, and other gases. Joining of similar and dissimilar materials is the main advantage of electron beam welding with high depth to width ratio as well as sharp focus at the point where parts are to be we...

A liquation cracking mechanism of dissimilar Al alloys during the friction stir welding (FSW) is suggested in this study. To identify the mechanism, the precipitates were analyzed and Al-Mg-Cu phase diagrams were calculated. Electron backscattering diffraction (EBSD) analysis and electron probe microanalysis (EPMA) were also conducted. In the same manner as constitutional liquation, at high hea...
