Heat source models in welding II — Lesson 2

This lesson covers the concept of heat source models in welding processes. It delves into the intricacies of ellipsoidal heat source models, double ellipsoidal heat source models, and quadruple ellipsoidal heat source models. The lesson also discusses how these models can be used to calculate the maximum intensity of heat flux, estimate distribution parameters, and understand non-symmetric energy distribution. It further explores the adaptive heat source model, which eliminates the need for pre-defining heat source parameters. The lesson concludes with a brief introduction to the configuration heat source model and the conical heat source model.
