Abstract:

Friction stir welding is a solid-state welding technique that utilizes thermo-mechanical influence of the rotating welding tool on parent material resulting with monolith joint-weld. On the contact of welding tool and parent material, significant stirring and deformation of parent material appears, and during this process mechanical energy is partially transformed into heat. The paper describes the software for the numerical simulation of friction stir welding developed at Mechanical Engineering Faculty, University of Nis. Numerical solution for estimation of welding plates temperature is estimated using finite difference method-explicit scheme with adaptive grid, considering influence of temperature on material's conductivity, contact conditions between welding tool and parent material, material flow around welding tool etc. The calculated results are in good agreement with the experimental results.

Abstract:

Welding as a modern, highly efficient production technology found its position in almost all industries. At the same time the demands on the quality of the welded joints have been constantly growing in all production areas. Great demand on the quality of the welded joints consequently causes more experimental or prototype – so called – validation joints that take place before the welding of final construction. These experiments, prototypes aim at – for instance – defining the appropriate welding technology, material, pre-heating, welding parameters, clamping condition and optimizing the welding process. Naturally, these experiments and prototypes make production more expensive. Numerical simulations of welding – in the area of production preparation as well as of production proper – have been frequently used recently. Numerical simulations supported by experimental measurements can simulate the actual welding process very close to reality. The new material models for hardness and mechanical properties prediction based on numerical simulation solution will be introduced.The paper covers some typical welding cases from energy industrial sector. The homogenous and heterogeneous weld joints from modern energy Cr-Mo-Ni-V steels (including modern austenitic steels) were done as prototype welding. The numerical simulation of these weld joints including post weld heat treatment process were done and welding technologies were optimised based on the numerical simulation results. The calculated hardness was compared with real measurements. During project the complete material properties which are needed for numerical simulation were measured. Simplify numerical lifetime prediction of weld joints including results from numerical welding analyse (as residual stresses and plastic deformation) were done.

Abstract:

Welding and heat treatment are a modern, high efficient production technologies. During last few years requirements for quality of the welded joints have been constantly increasing in all production areas. Unfortunately, this approach increases the cost of production due to demand of intense experimental or prototype work prior the use of technology to make a final product. Preliminary experiments have to take into account proper chose of welding technology, materials, welding parameters, clamping and final optimization the welding conditions. All of these activities can be supported or even replaced by numerical simulations based on finite elements method. Tremendous advance in field of numerical simulation, facilitates very high correlation of simulation and experimental results bringing this new approach to common use. This paper highlight to usefulness of numerical simulation in heat treatment of bulk materials in various production stages. It was shown that it is possible to predict formation of metallurgical phases, hardness distribution, strains and stresses during and after quenching process. Simulations of different heating conditions and cooling media makes it possible to simulate processes such as heating, quenching, carburizing and nitriding.

Abstract:

Analytic procedure for dissimilar materials welding problem by using developed in-house solver is applied on butt and lap jointed model. In addition, the procedure of data transferring between commercial package and in-house solver for the preparation of input data for in-house solver has been developed. Therefore we can use the commercial package as pre and post processor for in-house solver and the results from in-house solver, for example, welding residual stress can be exported to commercial package as initial value to the model and then further analysis with the application of external loading can be carried out. For the similar material welding the welding residual stress has been decided by temperature dependent material properties that are input to the source program. In the case of dissimilar welding problem due to the difference of expansion and shrinkage rate between aluminum and steel there has been a slight variation in this dependency. Since the aluminum has large thermal expansion coefficient and the mechanical melting point is lower than steel, the order and level of mechanical behavior like stress history become different. The degree of mechanical deterioration of dissimilar materials welded model has been assessed with various view aspects, namely, welding residual stress, plastic strain, equivalent plastic strain and plastic work distribution and it has been revealed that Al5052 is mechanically more sever than SPCC for same heat input.

Abstract:

Recently, underwater explosive welding shows its advantage in some difficult-to-weld combinations such as material with thin thickness, high hardness, and fragile quality. The pattern of the typical wave morphology in the interface of the welding specimen indicates the suitability of the selected experimental parameters and sound strength of the laminates. For the existence of the water, traditional Gurney formula and Aziz formula can not directly be used to evaluate the velocity and acceleration process of the flyer plate. Numerical simulation is necessary and irreplaceable for existing knowledge. Underwater explosive welding process was numerically simulated by ANSYS/LS-DYNA to explore the underwater shock wave and deformation process of the flyer plate. Velocity and pressure distribution of welding plates were obtained. The velocity of the flyer plate could satisfy the minimum velocity in explosive welding. It was found that water prevented the gross distortion and ensured the integrity of the composite laminate. Welding rate was increased by expanding the size of the explosive.

Abstract:

Different titanium grades are used in aircraft construction because of titaniums unique properties. These materials are mostly joined by different welding methods. Electron beam welding technology is often used in the aircraft industry to join structural elements made of titanium alloys. The goal of the work is a numerical analysis of the electron beam welding process applied to joining thin titanium sheets. The analysis was performed using finite element method, FEM. Temperature distribution, size of heat affected zone (HAZ), depth and width of fusion zone were determined for the assumed heat source model. Thermo-mechanical (TMC) simulation of the electron beam welding process using FEM is presented in the paper. The joining of two sheets, one made of commercially pure titanium Grade 2 and the other made of titanium alloy Grade 5 (Ti6Al4V), is analysed in the work. For the sheet welding process distributions of temperature, effective stress, and sheet deformation were calculated.

Abstract:

Laser welding of metals and alloys is extensively used in industry due to its advantages of controlled heating, narrow weld bead, low heat affected zone (HAZ) and its ability to weld a wide range of metals and dissimilar metals. Laser welding of dissimilar metals such as carbon steels and stainless steel is still a challenging task, particularly due to the formation of brittle phases in the weld, martensitic formation in the HAZ and solidification cracking in the fusion zone. These issues can significantly deteriorate the strength of the welded joint. The aim of this work is to investigate the fundamental phenomena that occur inside the dissimilar weld zone and their effect on weld quality. In order to establish the key process variables, an initial study concentrated on the effect of different laser process parameters on dissimilar weld quality. In the second part of the work, a comprehensive study was performed to understand and subsequently control the alloying composition in laser dissimilar welding of austenitic stainless steel and low carbon steel. A dissimilar weld that is predominantly austenitic and homogeneous was obtained by controlling the melt pool dynamics through specific point energy and beam alignment. The significance of dilution and alloying elements on joint strength was established. A coupled CFD and FEM numerical model was developed to assist in understanding the melt pool dynamics and transportation processes of alloying elements. The model has been validated by a series of laser welding experiments using various levels of specific point energy. The laser welding characteristics in terms of geometric dimensions, surface morphology, alloying concentration, and dilution, were compared, and it is concluded that the specific point energy and laser beam position are the key parameters that can be controlled to obtain a weld bead with characteristics most suitable for industrial applications. In the third part of the work, a comparative study was performed to understand the significance of cooling rate, and alloying composition on the microstructure and phase structure of the dissimilar weld zone. Results show that the HAZ within the high carbon steel has significantly higher hardness than the weld area, which severely undermines the weld quality. A new heat treatment strategy was proposed based on the results of the numerical simulation, and it is shown to control the brittle phase formation in HAZ of high carbon steel. A series of experiments was performed to verify the developed thermo-metallurgical FEA model and a good qualitative agreement of the predicted martensitic phase distribution is shown to exist. Although this work is presented in the context of dissimilar laser welding of mild steel to stainless steel, the concept is applicable to any dissimilar fusion welding process.

Abstract:

The objective of this study is the prediction of damage and residual stresses induced by hot processing which leads to phase transformation in martensitic stainless steel. This study firstly concerns the modelling of the damage of material induced by a complex history of thermoelastoplastic multiphase in heat-affected-zone (HAZ) of welding. In this work, a two-scale mode of elastoplastic damage multiphase was developed in the framework of thermodynamatics of irreversible process. The constitutive equations are coupling with ductile damage, elasoplasticity, phase transformation, and transformation plasticity. The experiments of 15-5PH were implemented for the identification of phase transformation, transformation plasticity and damage models. Tests of flat notched specimen were designed to provide the validation of damage model and strain localization using three dimensional image correlation technologies. In addition, microscopic analysis was performed to provide microstructure characterization of 15-5PH and to discover the damage mechanism. Finally the numerical simulation was performed in the code CAST3M® of CEA. We used the two-scale model including phase transformation, transformation plasticity and damage to simulate the level of residual stresses of a disk made of 15-5PH metal heated by laser. The internal variables, such as strain, stress, damage, were successfully traced in the simulation of two-scale model. The simulation results showed the transformation plasticity changes the level of residual stresses and should not be negligible; damage decreases about 8 percent peak value of residual stresses on upper surface of disk
L’objectif de cette étude est la prédiction du dommage et des contraintes résiduelles induites par des procédés haute température conduisant à une transformation de phase martensitique. On s’est intéressé plus premièrement à la modélisation du dommage induit par une histoire thermomécanique complexe, comme peuvent en produire les Zones Affectées Thermiquement de soudage. Nous proposons dans ce travail un modèle à deux échelles développé dans le cadre de la thermodynamique des processus irréversibles. Les équations de ce modèle couplent plasticité, endommagement, transformation de phase et plasticité de transformation. Nous avons réalisé de nombreux essais sur le 15-5PH en vue de l’identification des transformations de phase et des lois de comportement thermomécaniques. Les essais sur les éprouvettes entaillées ont été conçus pour valider les modèles d’endommagement ainsi que la localisation des déformations en utilisant la stéréo corrélation d’images. Les simulations numériques ont été effectuées avec le code CAST3M du CEA dans lequel nous avons implanté le méso modèle. Nous avons calculé l’état de contraintes résiduelles dans un disque de 15-5PH induites par un chauffage laser. En sus des contraintes, on peut suivre au cours du calcul les variables internes telles que l’endommagement ou les déformations anélastiques. Les simulations montrent que la plasticité de transformation modifie le niveau des contraintes résiduelles et peut ne pas être négligeable. Quand à l’endommagement, celui-ci fait décroître les valeurs maximales de contrainte résiduelles jusqu’à huit pourcent dans les zones les plus sollicitées

Abstract:

Welding has been one of the most extensively used joining processes for engineering applications and is the most frequently used process in nuclear power plants. Welding involves complex thermal, mechanical and metallurgical phenomena, affecting the microstructure of the material and generating internal or residual stresses and distortions in the process. Residual stresses are locked up stresses resulting from the thermal and/or mechanical processing of the parts. Residual stresses are inevitable and usually detrimental to the service life of a component often resulting in collapse or total structure failure. Numerous welding techniques have been developed over the past decades with the aim to reduce the residual stresses and enhance the performance of the component. These techniques need to be thoroughly studied and understood before implementing them in actual service. Electron beam welding and laser beam welding are two emerging techniques that are most promising because of many favourable features, including narrow fusion width to depth ratio, high welding speeds and capability to join metals that are dissimilar without any filler material. However to understand the full capability of these methods, it is essential to study the processes and their consequences on the joint. This dissertation presents the development of numerical and experimental approach to analyse electron beam welding and laser beam welding in a modified 9Cr-lMo (P91) butt welded plate. Modified 9Cr-lMo steel is used in nuclear power plants because of its high desirable properties such as strength and creep resistance at high temperatures. A number of simulation procedures using sequentially coupled thermo-mechanical analysis of the welding process are developed to study the welding process and the generation of residual stresses. The model incorporates the sol id-state phase transformation, exhibited by P9l steel during rapid cooling stage, which is the critical factor in the final residual stress field. The finite element models are validated using neutron diffraction measurements. The validated models are then used to study the influence of material properties, hardening models, annealing temperature and the boundary conditions on the final residual stress distribution . Also post-weld heat treatment used for relaxing the residual stresses due to welding is simulated and the extent of relaxation is studied. Uniaxial cross-weld creep tests are conducted on electron-beam welded samples to investigate the creep life. With the experience gained from modelling electron beam welding on P91 plates, an attempt has been made to develop a finite element model to simulate the electron beam welding of dissimilar metal welds in a butt plate made of P91 and AISI 316LN SS steels. The developed model is evaluated based on neutron diffraction experiments. Significant amount of effort has been directed towards developing an accurate and reliable numerical model to simulate the complex phenomena and severe non-linearity associated with welding processes such as temperature dependent material properties, hardening models, boundary conditions and solid-state phase transformation, which is the main purpose of this research. The residual stresses are predicted successfully. It is shown that the major contributor towards the residual stress profile is the volume change associated with the solid-state phase transformation during the cooling stage. Other factors such as temperature dependent thermo-mechanical properties, material hardening properties and boundary conditions have relatively less influence on the residual stresses.

Abstract:

Deformation and stresses in butt-welding of plates were studied. The work includes numerical simulation and experimental verification. The simulations were performed by use of the finite element method. Temperature dependence of material properties and phase transformations were considered. A thermo-elastoplastic material model was used. Plane stress conditions were assumed. Automatic butt-welding of plates without backing needs close tolerances of joint geometry. The thermally induced deformations and stresses are of great importance for joint geometry during welding. Therefore the change of gap width in front of the moving arc has been of special interest in these studies. The residual stresses, which may affect inservice behaviour of welded plates, were also calculated and measured. The tack-welds were found to influence the change in gap width in front of the moving arc. A proper tack-welding procedure is important in order to avoid large changes in gap width during butt-welding. The tack-welds should be made as soon after each other as possible. The sequence in which the tack-welds are made also affect the change in gap width. The gap width increased during the last part of the butt-welding in the simulations performed in this work. This increase was larger for wide plates than for narrow plates. Residual stresses close to the weld were large. The effective stress reached the yield limit of the material in the weld line.

Abstract:

L’allègement des structures est actuellement un enjeu industriel majeur. L’utilisation de certains alliages d’aluminium couplés à de nouveaux procédés d’assemblages est une bonne réponse à cette problématique. Le procédé de soudage FSW permet notamment la réalisation d’assemblages multi-matériaux en s’affranchissant des problèmes de fusion. Cette étude, réalisée au sein de l’entreprise TRA-C industrie, s’est intéressée plus particulièrement au cas du soudage FSW hétérogène d’alliages d’aluminium des séries 2xxx (Al-Cu-Mg-Ag) et 7xxx (Al-Zn-Mg), dans une large gamme de paramètres industriels. Les caractérisations des assemblages ont pu mettre en avant de fortes hétérogénéités microstructurales et mécaniques au travers des cordons. Ainsi la présence d’une zone faible, adoucie dans la ZAT du côté de l’alliage 7xxx, amène à favoriser la rupture en traction. Une évolution métallurgique importante déclenchée par le cycle thermique généré explique principalement ce phénomène. D’autre part, cette étude expérimentale a été couplée à des travaux de simulation numérique du procédé en configuration homogène. Le modèle éléments finis intègre, pour la première fois, la géométrie réelle et complexe (filetage, facettes, …) de l’outil de soudage utilisé expérimentalement et est couplé à l’utilisation d’une technique de maillage mobile. Cette technique numérique a permis de s’affranchir intégralement des distorsions de mailles conséquentes souvent rencontrées, ainsi que de décrire fidèlement les effets thermomécaniques engendrés par l’outil de soudage. Une étude de sensibilité aux paramètres de soudage ainsi qu’aux matériaux soudés a démontré une excellente corrélation entre les cinétiques thermiques expérimentales et numériques tout en démontrant l’aspect prédictif du modèle
The lightweight structures optimisation is one of the main topics in transportation industry. It can be achieved by optimisation of materials as well as induced assembly process. As a solid-state process, Friction Stir Welding (FSW) allows to produce dissimilar materials joining while avoiding fusion defects. This work focused on the dissimilar welding of aluminium alloys from 2xxx (Al-Cu-Mg-Ag) and 7xxx (Al-Zn-Mg) series in an industrial context. Joints characterizations were conducted at multiple scales to understand parameters impact on material flow, joint morphology, and performances. They have shown large heterogeneities in the microstructure as well as the global and local mechanical behaviour. Whatever the welding parameters used, good mechanical performance has been reached. A specific softened zone has been detected in the 7xxx alloy’s HAZ which caused fracture during transverse tensile test. Significant metallurgical evolution induced by thermal cycles mainly explains these phenomena.On the other hand, simulation works were also conducted to simulate the welding process in similar material configuration. The finite elements model integrates, for the first time, the real and complex tool design (thread, flats…). Complex geometry can be used by coupling with a specific moving mesh technique. This numerical development completely overcomes the consequent mesh distortion often encountered in FSW simulation. The current model presents good sensitivity and robustness for several welding conditions and materials. It also demonstrates an excellent correlation between experimental and numerical thermal fields while revealing the predictive aspect of the model

Abstract:

Numerical methods have been established to simulate welding processes, often based around the use of methods which represent the welding process in a simplified manner. Simplified methods include simultaneous deposition of weld beads and bead lumping where stringers or individual weld beads are grouped together and deposited. These approaches are widely accepted, however the requirement for simplified methods often results in compromises to the solution accuracy usually driven by limitations in data and the capability of computing hardware. In many cases this compromise in accuracy is acceptable providing it is well understood, however there are frequently cases where such simplifications are unacceptable and improved representation of the welding process is required. In practice this generally implies the requirement for a full moving heat source simulation. The transition from simplified simulation methods to the next technical step, full moving heat source simulations, is now possible for a wide variety of scenarios as will be demonstrated in this paper. This paper presents two specific cases, a 3 pass slot weld and a multipass repair weld, where full moving heat source simulations have been considered necessary. For each of these cases the reasons why moving heat source methods are necessary and the benefits that this more demanding simulation technique offers are described. Furthermore the predicted residual stress results are compared with residual stress measurements using a variety of measurement techniques. The work provides an extremely useful insight into how moving heat source methods are now considered a practical analysis method for a wide variety of real world problems. Of further consideration is the fact that in the 2 years since the work reported in this paper was undertaken computing performance would have at least doubled.

Abstract:

Issued from two successive RD studies in 1991–1995 for shipbuilding in France, a simplified method of numerical simulation of arc welding has been developed and validated on samples in full scale executed inside the shipyard. The metallurgical concept of the methodology is based on two main characteristic diagrams of iron-carbon steel: metallurgical phase transformation diagram and thermal dilatation diagram. In this paper, the simplified methodology is described with on its basic assumptions.

Abstract:

Pyramidal three-roll bending has the advantage of simple configuration and is widely used in manufacture. However, the bent shape has two planar zones near the front and rear ends. This paper proposes the modeling of the mecano-welding process which provides improved circularity of the bent shape. This process includes three sub-processes: the first sub-process is the roll bending from a plate with cylindrical rolls, the second sub-process which is the gas metal arc-welding process used to join the gap of the bent tubular section, and the third sub-process is the rerun roll bending of the welded shape. Results of the simulation of the first two sub-processes under the well-known ANSYS and ANSYS/LS-DYNA environment are reported. The bent shape after the first roll bending, the distributions of the temperature and residual stress after the welding are illustrated.
