Abstract
A component is formed by welding a plurality of sheets of metal to form a blank with a number of weld nuggets, placing the blank between a die section and a lid section, heating the die section to heat the blank, and introducing a pressurized gas between the lid section and the die section to press the blank into a mold in the die section to form a component. The number of weld nuggets has a desired thickness ratio between about 1.1 to about 1.25 such that the plurality of sheets of metal and the component formed have a number of characteristics that are substantially the same.
