The Temperature and Residual Stress Distributions of Butt Weld Pass on Nickel Alloy 690 Plate

The variations of temperature profile and residual stress distribution in the single V butt welds were studied in this work. The thermal elastic-plastic model of ANSYS finite element analysis software is employed in this study to simulate the melting and solidification processes of two clamped nickel alloy 690 plates with different welding parameters; i.e. the welding speed and the number of weld passes. The temperature dependent material properties are used. The effects of these welding parameters on the residual stresses around the weld are investigated. Numerical results reveal that these welding parameters may affect the distribution of residual stresses significantly.
