Abstract
A method of heat treating a workpiece, the method including projecting a laser beam from a laser source onto said workpiece, so as to produce a laser spot on said workpiece; projecting the laser spot onto different portions of said workpiece; and while projecting the laser spot, repetitively scanning the laser beam in two dimensions so as to produce a two-dimensional equivalent effective laser spot on said workpiece and thereby temper, reduce hardness of, enhance ductility of, and/or reduce brittleness of at least one of the different portions of the workpiece.
Claims22
A method of heat treating a workpiece, the method comprising:
- projecting a laser beam from a laser source onto said workpiece, so as to produce a laser spot on said workpiece;
- projecting the laser spot onto different portions of said workpiece;
- and
- while projecting the laser spot, repetitively scanning the laser beam in two dimensions so as to produce a two-dimensional equivalent effective laser spot on said workpiece, said effective laser spot having an amount of energy to temper, reduce hardness of, enhance ductility of, and/or reduce brittleness of at least one of the different portions of the workpiece.
