“…This was due to the much faster cooling rate in RFW process resulting in higher amount of martensitic and some bainitic structure within and near the weld interface. During FW process, the cooling was much slower as compared to the RFW, so ferritic and pearlitic with some bainitic structure was very likely to form [27], [28].…”

“…Temperature values at the beginning and at the end of transformation are conditioned by the speed of heating. Kinetics of diffusional transformation is described basing on Johnson-Mehl-Avrami-Kolmogorov equation [29,30], while martensitic transformation, basing on Koistinen-Marburger equation [31]. The calculation results of the volume fraction of the structural constituents, also thermal and structural deformations are discussed in [32].…”

Abstract. Analytical model of temporary and residual stresses for butt welding with thorough penetration was described assuming planar section hypothesis and using integral equations of stress equilibrium of the bar and simple Hooke's law. In solution the effect of phase transformations (structure changes and structural strains) has been taken into account. Phase transformations during heating are limited by temperature values at the beginning and at the end of austenitic transformation, depending on chemical composition of steel while the progress of phase transformations during cooling is determined on the basis of TTT-welding diagram. Temperature values at the beginning and at the end of transformation are conditioned by the speed of heating. Kinetics of diffusional transformation is described basing on Johnson-MehlAvrami-Kolmogorov equation, while martensitic transformation, basing on KoistinenMarburger equation. Stresses in elasto-plastic state are determined by iteration, using elastic solutions method with changeable longitudinal modulus of elasticity, conditioned by stress-strain curve. Computations of stress field have been conducted for one-side butt welded of two steel flats made from S235 steel. It has enabled a clear interpretation of influence of temperature field and phase transformation on stresses caused by welding using Submerged Arc Welding (SAW) method.
