Abstract

There is provided a method of preparing a sheet metal material for forming, the method comprising preparing the sheet metal material to have a desired resistance profile along an axis; heating the sheet metal material to a desired temperature by passing a current along the axis; and cutting the sheet metal material to define a blank for forming into a predefined arrangement. There is also provided a method of forming a sheet material
