Review on Finite Element Analysis of Temperature Distribution in Heat Affected Zone by Different Welding Process

This work has reviewed models and techniques for predicting the temperature distributions. The metal adjacent to a weld is exposed to severe thermal events. As a result, complex changes in metallurgical structure occur in heat affected zone region.When creating a numerical model, the aim is to implement the physical behaviour of the process into the model. However, it may be necessary to compromise between accuracy of the model and the required computational time. Different types of simplifications of the problem and more efficient computation methods are discussed
