NOTRE EXPERTISE
CONTRÔLE NON DESTRUCTIF
1. NON-DESTRUCTIVE TESTING DURING FABRICATION
GSI specializes in Non-Destructive Testing (NDT) of materials and metal structures, with over 10 years of experience, constantly seeking to improve its expertise and professionalism in this field, thanks to our qualified teams, certified according to international standards.
This enables our clients to manage risks, ensure product compliance, and monitor wear throughout its lifespan. Among other benefits, it ensures product safety and equipment integrity without causing damage.
Through our various conventional and advanced testing methods, we offer tailored services to control risks, reduce delays, and minimize costs.
Advanced NDT
GSI employs "advanced" NDT techniques to develop its skills and continuously evolving services. These techniques are used both for new applications where they provide efficient and innovative solutions and as replacements for conventional methods. GSI evolves its NDT processes to provide ever greater expertise, guaranteeing quality and safety for its clients.
The advanced methods used by GSI differ from conventional approaches in four essential points: massive data acquisition during testing, use of cutting-edge hardware and software, implementation of highly elaborate and qualified procedures, and execution by highly skilled and certified operators.

MULTI-ELEMENT ULTRASONIC TESTING
PHASED ARRAY
Multi-element ultrasonic testing or Phased Array is a Non-Destructive Testing (NDT) method used to detect discontinuities in manufactured parts such as welds or rolled products. This non-invasive technique is also used to evaluate the degree of material corrosion by detecting potential density loss.

EDDY CURRENT TESTING
Eddy current testing is a non-destructive method for detecting defects on a metal surface, such as cracks or discontinuities. High-frequency electromagnetic interactions enable the detection and evaluation of these surface defects manually or automatically, as required.
Under optimal conditions, defect resolutions of up to 30 µm are possible. Eddy current testing is typically contactless, avoiding damage or contamination of the tested surface.
Modern sensors, electronics, and software offer numerous application and analysis possibilities in metal production and processing, as well as portable formats for maintenance purposes.

MAGNETIC PARTICLE TESTING
Magnetic particle testing is a magnetization control technique applied by the action of a continuous or alternating magnetic field on ferromagnetic materials such as steels (except austenitic steels), cast irons, etc.
Magnetic particle testing uses various magnetization means and different products to adapt testing to the shape of the part, the orientation of the sought defect, etc. The testing method is fast because the magnetization phenomena are immediate.

PARTICLE TESTING INSPECTION
Particle testing inspection is a surface testing technique used to detect defects penetrating all types of non-porous materials. It is a simple technique to implement, requiring rigorous execution to ensure optimal sensitivity.
Particle testing inspection exploits the capillary properties of the products used.
ULTRASONIC TESTING
Ultrasonic inspection (also known as UT testing) is a Non-Destructive Testing (NDT) method aimed at detecting possible flaws inside a material. This technique allows the precise location and dimensions of existing flaws or discontinuities to be determined. The frequencies used in ultrasonic testing range from 500 kHz to 20 MHz and are therefore inaudible to the human ear.

VISUAL INSPECTION
This testing technique is performed with the naked eye and allows the detection of any surface anomalies. It can be classified as a form of NDT. However, this testing is the only one that does not require any particular technique.
It is based on observation : it is therefore necessary to define observation conditions and optimize them.
VACUUM BOX TESTING
Vacuum box examination is an NDT (Non-Destructive Testing) method used to verify the tightness of welded joints. This process uses a vacuum box or vacuum chamber, often made of Plexiglas, in combination with a vacuum system to generate a pressure differential. A reactive agent, which generates bubbles, is applied to the surface being tested.
The primary purpose of this leak testing method is to identify leaks in systems that cannot be conventionally pressurized. In case of a leak, the reactive agent creates bubbles, providing a visual indication of the leak.
HARDNESS TESTING
This NDT test involves pressing a penetrator, whose shapes and dimensions vary depending on the type of test, into the metal to be tested. The load is constant, and the surface or depth of the imprint left in the material is measured. The imprint will be more significant the softer the material is.
