Nov 11, 2022· A significant difference between AWSJ cutting and AWIJ cutting is the absence of air in the AWSJ technique. Due to the absence of air, the pressurized water jet with abrasive grains does not expand during cutting, resulting in a lower kerf width and higher precision cuts. So, an abrasive water suspension jet cutting tool can create …
