The technology of a high-speed water jet cutting and disintegration of various materials attained considerable growth during the last decades.Continuous high-speed water jets are currently used in many industrial applications such as cutting of various materials,cleaning and removal of surface layers.However,despite the impressive advances made recently in the field of water jetting,substantial attention of number of research teams throughout the world still paid to the improvement of the performance of technology,its adaptation to environmental requirements and making it more beneficial from the economic point of view.An obvious method of the water jetting performance improvement is to generate jets at ultra high pressures.The feasibility of cutting metals with pure water jets at pressures close to 690MPa was investigated already in early nineties of the last century.This chapter shows an alternative approach how to eliminate the need for such high pressures by pulsing the jet.
