Cut safely and efficiently
WAS cutting technology
Water Abrasive Suspension (WAS) cutting process
With the Water Abrasive Suspension (WAS) cutting process, almost all materials can be cut with the aid of a cold high pressure water jet and sharp-edged abrasive. The cuts are executed in a contact-free manner, with no heat generation or deformation. This specialised technology is used both in air and under water. Depending on the area of application, it enables the remote-controlled cutting of materials of up to 1,000 mm thickness from up to 1,000 m away.
How does the Water Abrasive Suspension (WAS) cutting process work?
Fields of application
- Dismantling and maintenance of offshore installations above and under water
- Disarming of unexploded ordnance (EOD) and improvised explosive devices (IEDD)
- Dismantling and maintenance of a wide variety of installations in sensitive, explosive or radioactive areas
- Industrial manufacturing
- Challenging cuts in extraordinary situations
Key Features
- Cuts almost any material
- Cutting in air and under water
- Cold cutting process
- Contactless cut
- No sparking
- Suitable for ATEX-zones and cutting explosives
- High cutting performance even with very thick materials
- High cutting quality, post processing not required
- Remote operation from a large distance
- Low particle emission
- Low noise emission
- Energy efficient
The WAS cutting process in brief
The Water Abrasive Suspension (WAS) is fed to the cutting nozzle via a high-pressure hose and pressed through it. The potential energy represented by the pressure and the flow is converted into a cutting jet with a velocity of several hundred meters per second.
The result is a two-phase cutting jet consisting of approximately 97.5 vol. percent water and 2.5 vol. percent abrasive. Since the abrasive particles in WAS systems are bound directly in the water, the suspension jet is much more stable, precise and powerful than the injection jet.
Components of a WAS cutting system
The core components of a Water Abrasive Suspension (WAS) cutting system are a high pressure pump, an abrasive mixing unit (AMU) and a nozzle.
Depending on the application, specialised remote-controlled cutting devices, monitoring and control systems as well as other accessories are deployed
