Abstracts: The welding joints in chemical reactor vessel are mainly affected by different parameter which may result into weld defects. The present study aims at understanding the influence of welding parameters of critical weld joints of a reactor vessel. In chemical reactor there are different critical weld joint positions like top dish end & nozzle, main shell long seam, circumferential joint etc. So, it is required to study different parameters, current setting, preheating, voltage, position of joint, filler material etc, to prevent or reduce the weld defects.
