This paper provides a clear insight into the structural integrity assessment issues associated with bimetallic welds at elevated temperatures. since the SYSWELD model doesnt have a stress-free crack surface. Any failure of the bimetallic welds can lead to grave consequences, not only speaking of huge monetary losses resulting from non-utilization of the nuclear reactor setup, but also immensely valuable and irreparable loss of human life. (2) Residual stress in crack surface after fusion welding (3) Cross view of in. Inspection difficulties, variability of material properties and residual stresses all combine to create problems for structural integrity assessment in these welds. Bimetallic welds are a common feature of light water and pressurized water reactors in connections between ferritic steel components and austenitic stainless steel piping systems used at elevated temperatures. Catastrophic failure of any structure can be avoided if structural integrity is assessed timely and necessary precautions are taken at suitable time. Proper evaluation of the structural integrity of any structure (nuclear reactor, aircraft, ship, railways, bridges, gas and oil transmission pipelines, etc.) is important to ensure public safety, environmental protection, and economic sustenance.
