The present paper summarizes the state of the art developments in numerical modeling and simulation of sheet metal welds commonly known as Tailor welded blanks (TWB). This metal forming process gained lot of importance in recent times due to its vast applications in automotive and aircraft industries. The blanks which consist of different thickness, material and shapes are welded together and forming is carried out. Mechanical and metallurgical properties of weld zone, effect of thickness ratio, material combination and weld line movement were studied in detail. It is noted that very few studies were made towards the experimentation and simulation of TWBs at elevated temperatures.
