What is CWJP?
Under Water
Cavitation Bubbles
How CWJP Works Cavitation is generated by high-pressure water jets underwater with a special cavitation-accelerating nozzle. When the bubbles collapse near the workpiece, peening effects are achieved with GPa-class impact.
GPa Class Impact
Collapse
Processing Examples Prevention of stress corrosion cracking of welds in structures. Improve compressive stress of aerospace parts, molding parts, additive manufacturing parts, automotive parts, etc.
