A Study on Failure of Welded Lap Joints in Alloy 718
It is well known that alloy 718 shows excellent mechanical strength and corrosion resistance and this alloy is now successfully utilized for aerospace and oil industry application. In order to design and manufacture components to satisfy the design requirements of the applied system, it is necessary to consider formability and weldability of the material. This paper provides experimental results of lap shear strength of welded specimens of alloy 718 with EBW(Electron Beam Welding) and LBW(Laser Beam Welding) and Brazing. The purpose is to determine the optimum welding method for overlap welding of alloy 718 for blow forming.
