Waterjet surface preparation is typically performed using pressures from 20,000 to 40,000 psi with rotating nozzle heads varying from 2 inches to 16 inches in diameter. Materials removed include coatings, oxidation and scale.
But how do variables like standoff distance, traverse speed, surface speed, rotation speed, and head design affect the efficiency of material removal? Research looking at these variables using test specimens showed that feed rate had the greatest effect on performance and also directly affected efficiency. The next strongest parameter was the design of the jetting head.
