Tailor welded blanks are sheets made from different strengths and thicknesses of steel pre-welded together before pressing and shaping into the final component. They produce high-quality components with the right grade and thickness of steel where they are most needed, providing significant savings in weight and processing costs in such industries as automotive engineering. Part 1 of this book reviews processing issues such as product design, production methods, weld integrity and deformation. Part 2 discusses applications in such areas as automotive and aerospace engineering.
