Here are the tests carried out:

• Internal and external visual inspection
  • Surface
  • Covering
  • Structure
  • Etc.
• Leak test
• Accessory check

OmniTest NDT offers a customized manufacturing monitoring service at the factory or the building site.

OmniTest NDT offers a customized inspection service of your building's enclosure. Buildings require a diligent and rigorous preventive maintenance by the owners. This is especially true for the façades of high-rise buildings that are exposed to the elements. The consequences of a broken façade are serious and need to be avoided. Since March 18th, 2013, Bill 122 requires owners of buildings of 5 floors or more above ground to call on a recognized inspector to inspect the façade of their building every 5 years

OmniTest NDT suggests being your eyes to scrutinize the façade, to record our observations and to make recommendations in a detailed inspection report. This information will help you make informed decisions by giving you an overview of your building's condition.

Subcontracting: OmniTest NDT offers to be their eyes to architectural or engineering firms in the field; we have at your disposal experienced inspectors. For hard-to-reach areas with traditional means, no problem! We can provide you with rope workers accredited by the S.P.R.A.T.

Do you need to bore a hole or trench through which a water pipe, a post-tension cable or reinforcing steel passes? The original drawings, when available, sometimes don't represent the reality of the land; to avoid bursting a water pipe or cutting a post-tension cable, call on our services.

OmniTest NDT offers a customized service to locate reinforcing bars, ducts, air pockets, post-tension cables, etc. We can mark the detected components directly in the inspected area, which allows you to carry out your work faster. Our equipment also allows us to have a 3D view of the assessed section, which is very appreciated by our customers.

OmniTest NDT offers a customized inspection service for your structural bolts. Bolted connections are one of the most common types of connection in the construction of metal structures. The inspection of bolted connections ensures that the joint can withstand the load. So, it is critical to fully understand the process. Here are some of the parameters we can inspect:

• Crack detection in the volume of the bolt
• Verification of the minimum tension of the ASTM A325 and ASTM A490 bolts with a tensiometer (Skidmore)
• Rotational capacity test of a coated bolt (ROCAP)
• "Turn of the nut" test
• Checking the tightening torque vs. tension in the bolt
• Etc.

OmniTest NDT offers a customized inspection service for your power transmission shafts. During its life, this type of component experiences several cycles of torsion, bending and shearing stresses. So, fatigue can be felt and signs of failure may appear. Our non-destructive inspection techniques allow us to check the physical integrity of your power transmission shafts directly on the machine onto which they are installed and prevent their breakdown.

OmniTest NDT offers a customized inspection service for pins. These components are ever-present in the industrial field and their strength is critical. The pins on the axles of a lifting platform, the pins of a winch brake system in a mine or the hanger pins on a bridge may be inspected on site. Our non-destructive inspection techniques allow us to check the physical integrity of your pins/axles directly on the machine onto which they are installed and thus prevent their breakdown.

Visual inspection was the first non-destructive control procedure to be born; it is characterized by the use of a person's five senses in conjunction with non-specialized tools such as a measuring tape, a set square, a welding gauge, etc. The visual inspection of an object, a structure or an assembly detects surface defects, but also validates the profile of a welded joint and respects of the dimensions such as an effective throat. Moreover, the manufacturing monitoring ensures that plans and specifications have been met. The overall dimensions of a beam, or measuring the profile of a welded joint are examples. This method is both simple and very flexible, but it requires in-depth knowledge of current standards.

This kind of inspection is widely used for maintenance and insurance quality in several fields. In addition, most of the codes require a visual inspection before any other type of inspection. For example, the CSA W59 standard requires that all welded joints be visually inspected for any welded assembly.

This method allows for:

• The inspection of welded joints (surface cracks, blow-holes, welding profile, plate alignment, etc).
• The inspection of lifting equipment, pods, lifting platforms.

At OmniTest NDT, our technicians are experienced and certified by the Canadian Welding Bureau as per the CSA W178.2 requirements.

This kind of inspection is fundamentally the same as the visual inspection; however, it requires a camera hence the term "remote". The operator guides a camera and looks at the transmitted images with a screen. Thus, a visual inspection may be performed in restricted and/or remote areas such as pipes, pumps, small tanks, etc.

Here is a typical list of applications:

• Visual inspection of welded joints inside a pipe
• Inspection of a reduction gear on the wind turbines to get an enlarged view of the gear teeth or other critical parts without having to dismantle the casing, despite limited internal access.
• Visual inspection in an area at risk for health (chemicals, high temperature, etc.)

OmniTest NDT owns cameras of different lengths and diameters. OmniTest NDT offers these customers the opportunity to record the images taken during the inspection in the desired format (.mpeg, .mp4, .mov, etc.). So, the customer owns a video of the inspection for future reference.

Magnetic particles inspection is a non-destructive control technique that consists of subjecting an area to the action of continuous (DC) or alternative (AC) magnetic field. This magnetic flux is disturbed when it meets a discontinuity slightly below the surface and at the surface. This disruption, which is called a leakage field, is showing a discontinuity in the material. Thus, with colored or fluorescent fine magnetic particles by a dry or wet method, it is possible to locate the defects up to 3 mm below the surface.

The magnetic particles inspection control has a very high sensitivity to small surface signs. As well, the geometry of the component to be inspected has very little impact on the results. However, the inspected material must be ferromagnetic. Thus, carbon steels, ferritic steels, martensitic steels and cast irons are typical materials for the video recording inspection. Nonetheless, contrary to popular belief, not all steels are ferromagnetic; for example, austenitic steels.

Below is a list of typical applications for this technique:

• Inspection of cast parts (network of surface or internal cracks)
• Inspection of forged parts (surface tears, cooling cracks, shrink marks, etc.)
• Inspection of welded joints (all types of cracks, lack of penetration after back gouging, lack of fusion between the base metal and the connection, etc.)
• Inspection of drive shafts (fatigue cracks)
• Inspection of pressurized tanks

OmniTest NDT uses portable electromagnetic cylinder heads that allow these inspectors to inspect parts in a workshop as well as on site, when in use. This technique allows the inspection of a large area or many parts quickly, easily, and at low cost.

Penetrant testing, also known as a "penetrating liquid", is a method for revealing surface-breaking discontinuities on non-porous materials. Penetrant testing consists of swabbing (by immersion or spraying) the component with a colored or fluorescent liquid. By the principle of capillarity, the liquid penetrates the discontinuities, hence the name "penetrating liquid". After cleaning the penetrating liquid in excess on the component, a developer is applied. The developer makes the liquid remaining in the cracks "sweat" in order to locate the discontinuities visually.

This very simple method is very sensitive to open discontinuities. We can reveal discontinuities of 1μm of opening, whatever their position or orientation is. However, penetrant testing requires an impeccable preparation of the inspected surface. The surface of the part must be free of dirt, grease or paint that can block discontinuities.

This method can be used for:

• Inspecting cast or forged parts (cracks, porosity, shrink marks, etc.)
• Inspecting parts after a heat treatment (cracks)
• Inspecting welded joints (cracks, porosity, lack of fusion to the connection, overlaps, etc.)
• Inspecting the surface after machining
• Inspecting superficially non-ferromagnetic parts

Ultrasonic testing is based on the transmission, reflection, and absorption of an ultrasonic wave spreading into the part to be tested. The emitted wave front is reflected at the bottom of the part and/or on the discontinuities, and then returns to the transducer (which often acts as a transmitter/receiver). The interpretation of the signals allows for an accurate positioning of a surface or a defect. This technique allows for a high accuracy and the ability to determine the depth of a defect as opposed to X-rays. It also makes it possible to measure the thickness of a part by accessing only one face (pipe, tank wall, large plates, etc.).

Conventional ultrasonic testing can be used on a broad range of ferrous and non-ferrous materials, as well as on non-metallic parts. Typical applications are:

• Inspecting welded joints and base metal.
• Measuring the thickness of a component to assess the damage due to corrosion or simply to check the punctual thickness of an aluminum prototype in some areas to validate the design of the mold.
• Detecting the presence of non-metallic inclusions on high-thickness steel sheets which may affect its mechanical properties.
• Locating and sizing discontinuities such as cracks, porosity, lack of fusion, etc.

The equipment used by OmniTest NDT is cutting-edge. It is light and portable. Our equipment can record screenshots or complete scans of thickness on a pipe's circumference. Moreover, our technicians are certified CAN/CGSB-48.9712 and EN 473/ISO 9712.

This inspection technique, also called "Phased Array", relies on the same basics as conventional ultrasounds. However, as the name suggests, the transducers are equipped with several components. Thus, with the interaction between the various piezoelectric components of the Phased array probe, the ultrasonic beam can be electronically guided and covers a larger area without having to move it. Therefore, this type of test can be used in a broad range of fields and its great versatility allows it to set up solutions dedicated to geometrically complex parts.

In concrete terms, this method allows for:

• Inspecting and developing inspection methods of complex geometries.
• Detecting and sizing discontinuities (cracks, porosity, lack of fusion, "delamination", etc.)
• Using an array of inspection angles with a single transducer.
• Recording a 3D thickness mapping of a pipe or tank wall to validate the residual thickness.
• Checking the adherence to claddings on a wall.
• Inspecting a welded joint and recording the signal to get a 2D image of it.
• Scanning an area 50% more quickly than with a conventional ultrasound probe with transducers that reach a 6-inch width.
• Obtaining a much higher ultrasonic sensitivity than conventional ultrasounds.

OmniTest NDT's highly-qualified operators can develop complex inspection procedures, write suitable procedures and inspect your components according to your needs.

Georadar control is based on the transmission and reception of electromagnetic waves. By measuring the distance and the speed at which these waves return to the receiver, we can estimate the position and the type of material found in the concrete. Several factors affect this wave path, including the dielectric constant and the electrical conductivity of the materials passed through the sound. Interpreting the signals can detect, among other things, rebars, post-tension cables, air pockets and water pipes. Access only to one side of the surface to be inspected is required, unlike the X-ray technique where both surfaces must be exposed. Moreover, this technique is not harmful to health, because the waves projected into the material are equivalent to cellular waves.

OmniTest NDT offers this cutting-edge technology to its customers for examining concrete in order to locate the above-mentioned items. Typical applications are:

• Locating reinforcements or ducts to avoid them during future drilling.
• Controlling quality to make sure the reinforcement is well positioned compared to plans and specifications.
• Checking the integrity of a wall, a floor or a concrete column.
• Checking the presence of air pockets in the concrete.
• Checking the thickness of a concrete slab.

The equipment used by OmniTest NDT is among the most efficient globally. It allows for the marking of items directly detected on the work surface and even to see the concrete slab tested in 3D.
