Modelling of stress field during Submerged Arc Weld surfacing taking into account heat of the weld and phase transformation effect
Journal Title: EAI Endorsed Transactions on Industrial Networks and Intelligent Systems - Year 2017, Vol 4, Issue 13
Abstract
In work the model of stress calculation and analysis of stress field during single-pass SAW (Submerged Arc Welding) surfacing have been presented. In temperature field solution the temperature changes caused by the heat of weld and by electric arc have been taken into consideration. Kinetics of phase changes during heating is limited by temperature values at the beginning and at the end of austenitic transformation, while progress of phase transformations during cooling has been determined on the basis of time-temperature-transformation (TTT) - welding diagram. The stress state of thermal loaded flat has bean described assuming planar section hypothesis and simple Hooke’s law and using integral equations of stress equilibrium. Dependence of stresses on strains is assumed on the basis of tensile curves of particular structures, taking into account the influence of temperature. The analysis of stress state has been presented for SAW surfacing S355 steel plate.
