Water jet cutting is a fabrication process that relies on the principles of erosion. It involves pressurizing water—sometimes mixed with abrasive media (e.g., garnet)—to up to 392 MPa and projecting it from a small-bore nozzle. The result is a high-pressure, high-speed stream of water (i.e., water jet), which can be used to cut a wide range of materials for various industries and applications. Softer materials (e.g., foam and rubber) are generally cut using pure water jets, while harder materials (e.g., metal and stone) are typically cut using abrasive water jets

Compared to other cutting methods, water jet cutting offers numerous advantages. That’s why it is used for many manufacturing projects. Below, we highlight three of the top reasons why you should consider using the water jet cutting process in your next metal fabrication project. 

1. It accommodates many materials.

The water jet cutting process is suitable for cutting virtually any material. It is most commonly used in metal fabrication operations to cut metals such as:

  •  Aluminum
  • Brass
  • Nickel
  • Steel
  • Titanium

2. It cuts without heat.

Unlike most other cutting methods, water jet cutting is considered a cold cutting process. Since only the water jet touches the workpiece during cutting operations, little to no heat is generated. As a result, there is no risk of thermal damage, such as warping or discoloration. This quality makes the process suitable for processing heat-sensitive materials and making components that cannot have thermal distortion. Additionally, it eliminates the need for secondary finishing operations to resolve any thermal damage on the component, which helps reduce production costs. 

3. It can create complex shapes.

The water jet cutting process has the ability to cut basic to highly complex shapes. It can cut, drill, and slice a wide  range of designs into flexible or rigid materials without causing damage. This versatility enables manufacturers to create a variety of elements, such as bevels, corners, and holes, and various components, both two-dimensional and three-dimensional. Plus, water jet cutting can also create near net shape components from plate material.

The equipment used in water jet cutting—i.e., water jet cutters—can be operated manually by human workers or automatically by computer software. The latter option is generally used for components that require a high degree of accuracy and precision.
