“…Initially, this theoretical development was generated for the arc welding process, however, in the research studies Rosenthal used a linear and point-type heat source. Also, Rykalin (1957) presented a model developed in an analytical way, where he made models for other processes since he considered the influence of the cooling rate on the mechanical properties of the welded parts. However, Pavelic et al (1969) Friedman, (1975 was the first to develop a model different from the one presented by Rosenthal and Rykalin, since the author defined the heat source under a Gaussian distribution.…”

The dominant phenomenon in laser welding processes is heat transfer by conduction, making it crucial to gain insights into energy distribution within the heat-affected region, including the melt pool. Thermal analysis enables the description of thermo-mechanical, metallurgical aspects, and also addresses studies related to fluid flow and energy transfer. As research in welding processes has advanced, these models have evolved. This is why it is now efficient to use computational modeling techniques as it allows us to analyze the behavior of laser welding during the process. This underlines the importance of this work which has carried out an exhaustive theoretical literature review with the objective of classifying and describing the numerical simulations of laser welding based on the physics involved. In that sense, the mathematical models and strategies used in laser welding are explored in a general way. Therefore, two types of laser welding by conduction and deep penetration are defined from this point and they are categorized according to the phenomena involved in Model Heat Conduction and Model Integral Multiphysics. This comprehensive review article serves as a valuable resource for higher education students by providing a structured and detailed exploration of laser welding and its mathematical modeling. By classifying and describing numerical simulations based on the physics involved, it offers a framework for students to understand the complexities of this field. Additionally, this innovative approach to organizing and presenting research contributes to educational innovation by facilitating a more efficient and effective learning experience, helping students acquire the knowledge and research skills necessary for advancements in the laser welding domain.

Calculation of Thermal Processes In Flash Butt WeldingFor the calculation of the thermal processes in flash butt welding the Fourier equation for heat conduction is used paying regard to resistance heating. With a model of calculation the assumptions and simplifications made can be explained. Cooling of the clamps, losses by flashing and heat transfer arc taken into account. The input of heat at the gap can bc treated as a flat heating source. Particularities with respect to preheating, flashing and cooling may be introduced into the calculation by corresponding inital and boundary conditions. As a result we get the dependence of temperature on the welding parameters. Experiment and calculation are in good agreement.
