Dr. Norman Franz has long been recognized as the father of the waterjet. He was the first to study ultra-high pressure (UHP) waterjet cutting tools. Ultrahigh pressure is defined as greater than 30,000 psi. Dr. Franz was a forestry engineer who wanted to find a new way to cut large tree trunks into lumber. In 1950, Franz was the first to place a heavy weight on a column of water, forcing the water through a tiny nozzle. He gained brief jets of high pressure (many times exceeding the current pressure) and was able to cut through wood and other materials. His later research involved more continuous flows, but he found that obtaining continuous high pressures was very difficult. At the same time, part life was measured in minutes, not weeks or months as today.
Dr. Franz never built a mass-produced wood cutter. Today, wood cutting is one of the least important applications of ultra-high pressure technology. But Dr. Franz demonstrated that high-speed converging water has tremendous cutting power—power that has applications far beyond Dr. Franz's dreams. In 1979, Dr. Mohamed Hashish, working at Flow Research Laboratories, began researching ways to increase the energy of waterjet cutting to cut metal and other hard materials. Dr. Hashish is considered the father of abrasive waterjet, having invented the method of adding abrasive to ordinary waterjets. He used garnet, a material commonly used in sandpaper, as the sanding material. With this method, a waterjet (containing abrasive material) is able to cut almost any material. In 1980, abrasive waterjets were first used to cut metal, glass and concrete. In 1983, the world's first commercial abrasive waterjet cutting system was launched and was used to cut automotive glass. One of the first users of the technology was the aerospace industry, which found the waterjet ideal for cutting stainless steel, titanium and high-strength lightweight composites used in military aircraft, as well as carbon fiber composites (already used on civilian aircraft). Since then, abrasive waterjet has been adopted by many other industries such as processing plants, stone, tile, glass, jet engines, construction, nuclear industry, shipyards and many more.

Therefore, the portable water cutting system has broad market application prospects and can meet customers' different requirements for cutting capabilities and operating environments. In past practical market applications, portable water cutting systems have shown superior results. It is mainly used in aerial bomb destruction, petrochemical pipeline cutting, dangerous goods processing, and flammable and explosive cutting operations. The application effect is obvious, and the existing safety hazards can be easily eliminated during the cutting process, making it the first choice for aerial bomb destruction, petrochemical pipeline cutting, oil tank cutting, and tanker drilling
