Laser Welding of Dissimilar Metals with Large Thickness Ratio

Abstract

Steam generators are critical components for the Prototype fast Breeder Reactor being designed at the Indira Gandhi Centre for Atomic Research, Kalpakkam. A leak in the steam generators can have serious consequences leading to rupture of steam generator tubes. Consequently, by introducing a known leak in the experimental loop, data is required to be generated which can predict the response of the material to the leak as a function of leak rate, time, temperature, steam pressure and the size of the microhole as a result of sodium water reaction.
