Special Issue Information

Dear Colleagues,

Welding processes are technologies that have been with us for a long time and are constantly developing. Modern construction materials and joining technologies, as well as rigid requirements for finished products, pose new challenges for engineers in their designs. A huge number of factors influencing the course and result of the welding process and a wide range of basic and additional materials, as well as the number of available welding technologies, open great opportunities for us. However, it also means that in order to control their interrelationships, we have to reach for modern supporting tools, such as undoubted numerical analyses of welding and heat treatment processes. Modern software today gives engineers the opportunity to learn more about the mechanisms occurring in modern materials subjected to the impact of the welding thermal cycle, supporting the design of modern, economical and, above all, safe welded structures. I invite you to send scientifically valuable articles for this Special Issue entitled "Numerical Simulation of Metals Welding Processes". Its scope is very wide and covers all issues of computer-aided use, in particular numerical analyses, in the design and diagnostics of welded elements and structures. The purpose of this Special Issue is to present the latest developments in the field of numerical simulations of welding, so articles should concern the issues of the numerical analyses of welding and heat treatment processes, as well as their use in the design and diagnosis of welded structures. Studies on the influence of the welding heat cycle on the properties, structure, stresses and distortions distribution of welded joints, supported by computational methods, are also welcome.

Laser beam welding (LBW) is a highly demanded process for premium-quality joints in aeronautic, energy, or industrial sectors, where flexibility and low-heat-affected zones are required. One of the main applications of LBW in the near future is expected to be the welding of new turbine engine components, which are typically made of Nickel-based superalloys. However, parameter setup is time- and resource-consuming, where experiment-based methods are typically employed. Therefore, the process development is far from an efficient resource utilization. In the present work, an LBW numerical model is developed and experimentally validated through a machine-integrated monitoring system. The LBW model is based on solving the heat transfer problem produced by the laser and provides the resulting temperature field, as well as the weld bead dimensions. The model includes a variable heat source that automatically adapts to the welding regime, conduction, or keyhole. For the model validation, two Inconel 718 sheets of different thicknesses are butt-welded and an error of around 10% is obtained, which ensures the validity of the model. Full article

In this study, numerical and experimental research of residual stresses was carried out on an I-profile structure model and welded by using the Metal-cored Arc Welding (MCAW) technique. The numerical research was carried out by sequential simulation, using the birth and death element in the thermal analysis, while the same was omitted in the mechanical analysis in order to speed up the calculation process. The measurement of residual stresses was conducted on the outer surfaces of the model at a depth of 0.015 mm below the surface. It was determined that the longitudinal stresses in the weld and its immediate surroundings are tensile, while towards the ends of the model, they change to compressive. Transversal residual stresses exist mainly around the weld itself, and the immediate surroundings and decrease towards the ends of the model. A high agreement between the numerical and experimental results was found. Full article
