What are the benefits of waterjet cutting compared to laser cutting?


Waterjet cutting and laser cutting are both popular methods for precise material cutting, each with its own strengths. However, waterjet cutting offers several distinct advantages that we will discuss in this article.

Unmatched Material Versatility


Waterjet cutting excels in its ability to cut a wide range of materials:

  • Can cut virtually any material, including metals, stone, glass, ceramics, composites, and even foods.
  • Easily handles reflective materials like aluminum, copper, and brass without issues.

In contrast, laser cutting is typically limited to metals, plastics, wood, and some composites. Reflective materials can pose challenges for laser cutters, potentially causing damage to the equipment.

No Heat-Affected Zone (HAZ)


One of the most significant advantages of waterjet cutting is its cold cutting process:

  • Generates no heat, eliminating the risk of heat-induced warping or structural changes in the material.
  • Ideal for heat-sensitive materials, such as certain plastics or metals that may harden or deform with heat.

Laser cutting, on the other hand, generates significant heat, creating a heat-affected zone that can alter material properties or cause warping.

Superior Thickness Capability


Waterjet cutting can handle thicker materials with ease. It’s capable of cutting through materials up to several inches thick, depending on the material type.


Laser cutting is typically more limited in thickness, with effective cutting usually up to about 0.75 inches (19 mm) for metals.

Excellent Edge Quality and Finish


Waterjet cutting produces superior edge quality and creates smooth, burr-free edges, often reducing or eliminating the need for secondary finishing operations.


Laser cutting may leave a heat-affected rough edge that might require additional finishing.

Enhanced Safety and Environmental Considerations


Waterjet cutting offers safety and environmental benefits. It does not produce hazardous fumes or gases, making it safer for operators and the environment.


Laser cutting can generate fumes that require proper ventilation and safety measures.

Waterjet Cutting: A Superior Choice for Versatile Applications


In conclusion, while both waterjet and laser cutting have their place in modern manufacturing, waterjet cutting offers unique advantages in terms of material versatility, thickness capability, edge quality, and safety. Its ability to cut a wide range of materials without heat-related issues makes it an invaluable tool for many industries and applications.
