Abstract
In this work, the effect of isothermal heat treatments at 300 °C on microstructure evolution after welding by Tungsten Inert Gas (TIG) welding technique of 304L pipeline steel have been studied. Microstructures of the weldments were investigated using scanning electron microscopy (SEM), X-ray diffraction analysis (XRD), and hardness measurements. Microstructural evolution in welded joint was identified. Results indicated that the microstructure of fusion zones exhibited dendritic structure. The applied heat treatments affected the microstructure of the welded joint. However some defects have been observed in weld joint.
