NDT IN THE VALUE CHAIN

ENGINEERING AND DESIGN

To ensure a cost effective life cycle for the product, structures must be designed and built with inspectability in mind. When engineering departments have easy access to NDT technology, the need for costly and time consuming involvement of external NDT partners can be minimized.

MANUFACTURING

It is imperative to monitor and control manufacturing quality. All process steps from QA of inbound parts through processing, assembly and final inspection must be carefully monitored. The consequence of letting flawed parts into the value stream can be costly and in worst case catastrophic.

IN-SERVICE

Composite materials are strong and light, but still fragile. BVID (Barely Visible Impact Damages) can be sign of structural weaknesses that are hard to detect by the human eye. As the use of CFRP increase in high volume products, service and maintenance organizations need easy-touse tools to verify structural integrity.

Technology

• The transducer is our core technology
• Transducer works as a speaker and a microphone
• High voltage electric pulses are transformed into acoustic waves.
• Acoustic wave is reflected and transformed into small electric pulse

Transducer

Ultrasound reflections

Application: Accidental Damage

Application: Small defects

Application: Drilled Hole Inspection

Drilling holes in composite structures can induce hole wall delaminations, reducing the mechanical properties of the structure. Conventional ultrasound NDT techniques are time-consuming given that inspecting each hole takes time and that there can be numerous drilled holes in an aircraft. Using the DolphiCam Drilled Hole Tool, NDT Operators can focus on critical inspection depths. Defects as close as 2 plies from the surface is easily detected. The DolphiCam collects the complete image without need the move the camera. The dry coupling transducer allows inspection of the hole without using couplant.

Application: Laminate/core disbonds

Application: In-Service inspection for non-experts

• Operator use prepre-programmed tool with traffic-light type indication
• User User-friendly software and easy to use camera!
• PDF report PDF created automatically
– Optional: Report evaluation by NDT Expert

Application: Medium area scanning

The DolphiCam GridToolTM is a mechanical positioning system that makes it easy to inspect larger areas with the DolphiCam. Its solid construction from high quality linear bearings ensure smooth scanning, precision and high inspection speeds. The GridToolTM is fixed to the surface by one or two large, powerful suction cups. Setup-time is usually less then 3 minutes! Due to the low weight, the system can be placed in any orientation, even inverted on painted or shiny surfaces. The suction cup can also be removed to allow for a bolted placement if needed. The attachment is hinged to allow access to non-planar surfaces.

Gridtool

• 500 x mm area
• Set -up < 3 minutes
• Adapt to curved surfaces
• Vertical, upside down…
• Affordable and quick!

Application: Large Application

LPS One

DolphiCam LPS One is a position-aware NDT system developed by DOLPHITECH. Using the DolphiCam 2D Matrix Array integrated with electro-optical measuring technology, the user can examine large composite structures by sliding the DolphiCam ultrasound camera freely over the surface.

• Fast and precise scanning of large areas
• Absolute positioning based on industry leading CMM (coordinate measuring machine) technology
– ~ 5 x m volume
– 40 x 32 º FOV
– 2D system (3D version planned)
– High positional precision and repeatability

Application: NDT for Teams

DolphiCam TeamCenter is a system solution for making non-experts capable of performing NDT inspections. The inspections are performed following guided procedures provided by the NDT Expert.

PREPARING THE SYSTEM

The NDT Expert uses DolphiCam Expert to finds the best camera settings for the given structures taking the material, thickness and other factors into account. Next, the Expert uses TeamCenter/Expert to make a TeamCenter library contaning inspection procedures for each critical area and distribute the TeamCenter library to his team of NDT inspectors.

PERFORMING THE INSPECTION

Automatically opening TeamCenter/Inspector with the correct library, the inspector navigates to the correct inspection procedure, and enter details on the object to be inspected. The camera is automatically set up with the correct settings for the procedure. At the end of the inspection, a PDF report is automatically created.
