Course Objective

A healthy way describing of metallurgical events depend on knowledge of temperature distribution on weld and around. This is depends on used welding method s temperature distribution at the time of welding. Before, during and after welding, the known of these matters and transposing them within the fallowing course content compose of the aim of this lecture.

Learning Outcomes of the Course Unit

1   To explain the structural changes associated with the weld.
2   To understand the temperature distribution during and at the end of melting.
3   To establish a relationship between residual stress and deformation caused by welding.
4   To establish a relationship between changes in mechanical properties weld and base metal, due to the joint effect of temperature and strain caused by welding.
5   To explain failure of cold cracking, depending on residual stress, hardening of steels and hydrogen input.
6   To understand the importance of processes after welding, such as weld post hardening , stress relieving, normalization and annealing.
