Assessment of Weld Overlays in Cladded Piping Systems With Varied Thicknesses

This paper continues the research previously done by authors on computer simulation of the dissimilar welded joints with varying clad thicknesses using numerical methods. For different cladding thicknesses comprising of stainless steel and mild steel, stress curves have been generated. The welding of the two dissimilar materials has been carried out in-house with the aid of a tungsten arc weld with dynamic measurement of the temperature profile in vicinity of the welding track using high temperature thermocouples. Comparison of the experimentally measured stresses from literature versus the simulation results shows close agreement.
