ABSTRACT
This paper presents an approach to simulate the in-service welding of type-B sleeves using finite element analysis (FEA) and induction preheating. To validate the models, numerical results of thermal cycles and temperature distribution are compared with experimental data. The maximum error in the tail out of the thermal cycles (cooling slope) was about 10%, while in the peak temperature, the error was about 5%. The cooling time between 800 ºC and 500 ºC (Δt8-5) was also estimated and the microstructure was predicted using continuous cooling transformation (CCT) diagrams.
KEY WORDS: Welding simulation; Finite element analysis; repair welding; Thermographic monitoring; High cooling rate welding.
