Compare and Contrast: Laser Cutting Vs. Waterjet Cutting

If you’re trying to figure out whether to opt for a waterjet cutting or laser cutting service for your project, you’ll need to understand that the service you choose will largely depend on your unique project needs. 

Waterjet cutting and laser cutting services offer similar results, however each cutting technique is ideal for different applications. 

While both techniques are great for manufacturing, our goal today is to offer a summary of both to better inform your decision-making process. Read on to learn more. 

Waterjet Cutting

Waterjet cutting is a type of manufacturing technique that cuts through a workpiece by focusing highly pressurized water on a small focal point to cut through material. The pressure can be adjusted to suit the needs of the application, and the water can be mixed with abrasive agents and other substances to maximize cutting capabilities. 

You might want to opt for waterjet cutting if your workpiece is composed of a highly reflective metal, as laser cutting cannot effectively cut through such metals as they can cause “flashback”. “Flashback” is what occurs when the laser’s beam of light is redirected back at the source - which can lead to damaging effects to the laser machine. 

Laser Cutting

Laser cutting operates by centering a high powered beam of light on a focal point to achieve precise and bold cuts. The focused beam of light effectively melts, vaporizes, or burns through the workpiece to achieve a sharp edge with a high quality finish. Many opt for laser cutting services when it comes to metal fabrication, making laser cutting equipment a mainstay in machine shops worldwide. 

You’d want to opt for laser cutting over waterjet cutting if your application requires a higher degree of precision. Laser cutting is known for its ability to achieve highly accurate cuts. Another reason why you may choose laser cutting over waterjet cutting is if you require engraving. Due to the precision laser cutting offers, it is also great for achieving highly intricate engraving designs.
