Abrasive water suspension jets (AWSJs) is a cutting-tool with advantages for submerged application. Long distances between the pressure generation, the mixture unit and the operating unit can be realised easily. However, the influence of the surrounding water on the cutting potential of AWSJs is higher than in atmospheric surrounding. To detect this influence experimental investigation were carried out in a special pressure chamber by the variation of the main process parameter. To quantify the cutting potential of the jet, kerfs on metallic material were produced under different ambient pressure. The influence of the process parameter like working pressure, nozzle diameter, abrasive flow rate, standoff distance and cutting speed were varied. The current paper describes the behaviour ofAWSJs in submerged surrounding of maximum 90 meter water depths and maximum working pressure of 140 MPa. The results of the investigation and there relevance for further developments were discussed.
