Laser Peeing


Laser peening (LP), or laser shock peening (LSP), is a surface engineering processes used to impart beneficial residual stresses in materials. The deep, high magnitude compressive residual stresses induced by laser peening increase the resistance of materials to surface-related failures, such as fatigue, fretting fatigue and stress corrosion cracking. The physics of the laser shock peening process can also be used to strengthen thin sections, work-harden surfaces, shape or straighten parts (known as laser peen forming), break up hard materials, compact powdered metals and for other applications where high pressure, short duration shock waves offer desirable processing results.


PAVETECH Co., Ltd successfully delivered the laser peening system for Nuclear Power Plant in Korea.
