Heat Source Model in Conduction Mode Welding Processes

This course covers the comprehensive understanding of heat source models in welding processes. It starts with the basics of welding heat sources, focusing on the analytical solution of different heat sources associated with the welding process. The course discusses the assumptions made in analytical solutions, such as representing the heat source as a point or line heat source, and their limitations in practical applications. It further delves into the mathematical equations that represent the distribution of heat in welding processes, and the geometrical considerations that need to be made. The course also explores different types of heat source models, including circular disk, ellipsoidal, and hybrid models, and how they can be applied to different welding processes. It also touches on the concept of adaptive heat source models and their advantages in certain scenarios. The course concludes with a brief introduction to the configuration heat source model and the conical heat source model.
