Abstract

Welding of two dissimilar materials was carried out in-house with the aid of a Tungsten Arc weld having dynamic measurement of temperature profiles in the vicinity areas of the welding track using high temperature thermocouples. Comparison was shown previously of the simulated and measured transient temperatures versus finite element simulation. Stress analyses of the pipe were carried out using FEA simulations with two different clad thicknesses. Results of thermal analysis showed a close match and laboratory tests revealed the occurrences at the welded joints, FZ and HAZ; the result of stress analysis also showed a good agreement when validated with ND experimental results.
