Abstract

A process and a system for creating internal stress in a metallic workpiece by laser shock peening is provided. In the process, a first laser pulse is applied to a treatment site of the workpiece covered by a surface layer. A second laser pulse follows the first laser pulse in time, and is applied to the treatment site of the workpiece. A covering layer, such as flowing water, is provided over the treatment site during the application of the laser pulses.
