Numerical Simulation of Fusion Welding Processes

This chapter is dedicated entirely to the numerical simulation of fusion welding processes. Initially, it introduces numerical simulation by discussing its historical background, fundamental concepts, and limitations. It thoroughly examines various types of analyses and models, focusing particularly on mechanical, thermal, and metallurgical aspects. Additionally, it discusses two types of heat source models along with their parameters and heat distribution mechanisms. The concept of mesh discretization and the available elements for it are also addressed. Finally, it briefly discusses the existing software for such simulations.
