Liquid penetrant testing (LPT), also known as dye penetrant inspection (DPI) or liquid penetrant inspection (LPI) is one of the most common and affordable solution and one of the oldest, if compared to non-destructive testing challenges.
The method leverages capillary action, i.e., the ability of a liquid to flow into narrow spaces without help, even in opposition to, external forces such as gravity—to detect surface-breaking defects.
The excess is removed and a developer is applied after applying the penetrant and letting it dwell for a certain period. From surface-breaking defects, the developer draws the penetrant where it’s seeped, revealing their presence.
Liquid Penetrant Testing is widely used in aeronautic, Automobile , Heavy Fabrication, steel structure fabrication and aluminium industry for welded or forged parts or castings.

Advantages:

• Quick and easy method;
• Affordable;
• Great at detecting surface breaking flaws;
• Applicable to ferrous and non-ferrous materials.

Magnetic Particle Testing (MT) is a common surface inspection technique based on inducing a magnetic field on the surface of a ferromagnetic material and spreading a powder or solution concentrated with magnetic particles that will align with the magnetic field. A crack will act as a dipole magnet for the magnetic particles to cluster.
Magnetic particle testing is a non-destructive test method, which can be used to inspect a variety of ferromagnetic components and products. These include castings, forgings and weldments. The method is used across different industry sectors, especially when determining if a component is fit-for-service.
This technique is used for surface or just below the surface discontinuity detection.

Advantages:

• Reliable, fast, and easy to pick up equipment;
• Test can be performed at any stage of a project;
• Independent from the part dimensions or geometries;
• Portable equipment.

Ultrasonic testing (UT)is done in materials to determine whether there are flaws or defects present in a material, and also to determine the thickness of a material. Ultrasonic testing methods use sound waves to find defects and measure thickness.
UT technology can detect small defects such as corrosion, pitting, abrasions, and cracking. It can also spot abnormalities on a volumetric level and can detect anomalies that other NDT methods may miss. However, certain UT techniques are more adept at reading flaws than conventional UT.
These include the use of ultrasound in medical diagnosis; in the treatment of certain diseases; in flaw-detection and navigation systems; for control systems in industry; for cleaning; in the operation of drills and saws; and in various metal-working processes.

Advantages:

• Internal defects can be detected and sized when a validated procedure is applied;
• Thick specimens take no more time to examine than thin ones, assuming correct instrumentation set up;
• Access to only one side of the component is needed.

The main use for ultrasonic thickness gauge (UTG)is in material thickness and quality testing in manufacturing industries. An ultrasonic thickness gauge apart from thickness testing can also check for defects that are otherwise not visible to the naked eye.

• Wall thickness determination. Ultrasonic thickness measurement is used to check wall depth or of materials. Wall thickness monitoring is important especially in industries where materials are subjected to high heat and pressure. In the petroleum industry, for example, high standards of wall thickness has to be maintained to avoid accidents and losses by explosion or leakages.
• Corrosion checking. Corrosion in simple terms is rusting. Frequent testing of metal surfaces for rust using an ultrasonic thickness gauge helps ensure structures meet expected standards, and minimizes safety risks. Constant monitoring for corrosion also helps reduce the need for frequent repairs saving you money and time.
• Material defect testing. One of the reasons that make an ultrasonic thickness gauge stand out from other thickness testing equipment is the ability to detect defects on solid materials.
• Measurement can be done from only one side of the sample material.
• Gives accurate measurements with readings as low as 0.1mm or less.
• Portable and easy to use and allows more measurements to be done within a short time.
• Settings can be done to manage testing on different metal coatings and linings.
• Have a wide measurement range

Phased Array Ultrasonic Testing (PAUT) is an advanced non-destructive technique that utilizes a set of Ultrasonic testing (UT)probes made up of numerous small elements, each of which is pulsed individually with computer-calculated timing (―phasing‖). When these elements are excited using different time delays, the beams can be steered at different angles, focused at different depths, or multiplexed over the length of a long array, creating the electronic movement of the beam.
PAUT can be used to inspect almost any material where traditional UT methods have been utilized and is often used for weld inspections and crack detection.
Time of Flight Diffraction (TOFD) is a reliable method of non-destructive Ultrasonic testing used to look for flaws in welds. TOFD uses the time of flight of an ultrasonic pulse to find the location of a reflector. It can also be used for weld overlays and the heat affected zones of other components as well such as piping, pressure vessels, clad material, Storage Tank, and structural steel.
Like most UT methods, TOFD works by emitting sound waves into a component and measuring the time from them to return. What makes TOFD different from other UT methods is that, rather than measuring only for the high amplitude sound waves that reflects off of the back of the component, it instead measures the response time of low amplitude waves that are diffracted by the tips of cracks.

Radiographic Testing (RT) is a non-destructive testing (NDT) method which uses either x-rays or gamma rays to examine the internal structure of manufactured components identifying any flaws or defects. In Radiography Testing the test-part is placed between the radiation source and film (or detector).
It is based on the principle that radiation is absorbed and scattered as it passes through an object. If there are variations in thickness or density (e.g. due to defects) in an object, more or less radiation passes through and affects the film exposure. Flaws show up on the film, usually as dark areas.
Radiographic testing is widely used in a variety of industry sectors including aerospace, power generation, construction, petroleum, chemical and automotive, and for all types of components and parts.
In industrial radiography there are several imaging methods available, techniques to display the final image, i.e. Film Radiography, Real Time Radiography (RTR), Computed Tomography (CT), Digital Radiography (DR), and Computed Radiography (CR).

Eddy Current Testing (ECT) is the process of running electronic probes through the length of various types of tubes or along the surfaces of materials in order to find flaws in them. An eddy current is a current that runs opposite to the current introduced by a probe into a conductive material.
Eddy Current Testing (ECT) is an electromagnetic testing method for nondestructive testing (NDT) of conductive materials. This method can be used in several applications such as crack detection, measuring metal thickness, detecting metal thinning, determining coating thickness, and measuring electrical conductivity and magnetic permeability.

Advantages of eddy current testing include:

• ECT is sensitive to and can detect small cracks and other defects
• ECT equipment is portable
• Minimum part preparation is required
• The test probe does not need be in contact of the part
• ECT can be used to inspect complex shapes and sizes of conductive materials

Positive Material Identification (PMI) is a rapid, non-destructive method of verifying the chemical composition of a metal or alloy. As a highly portable tool, it offers the quickest and most cost-effective solution to determining the chemical composition of a component or batch material.
Positive Material Identification (PMI) is a fast and non-destructive testing (NDT) method for verifying the chemical composition of metals and alloys. PMI can be used to verify that supplied materials conform to the proper standards and specifications.
Elements that can be identified using PMI include. Ti, V, Cr, Mn, Co, Fe, Cu, Zn, Ni, Se, Nb, Mo. Interesting to know is that the exposure of radiation is sufficiently low, so that extra safety measures are not required.
These instruments are highly accurate at determining the chemical composition of alloys, and thereby their grade. Moreover, they do so within a matter of 5 seconds or less for most stainless-steel grades, without significant sample preparation, and safely.

Ferrite content tests (Fe) can measure when the content is low and the welded material is susceptible to hot-cracking. Conversely, if the ferrite content is too high, a reduction in the toughness, ductility and corrosion-resistance of the steel can be tested.
The ferrite content can be measured by magnetic methods, quantitative metallography like for example planimetry, lineal analysis, or differential point counting [14] or by different methods using electron diffraction such as X-ray diffractometry (XRD) or electron backscatter diffraction (EBSD).
Ferrite testing is sometimes necessary to avoid material failure in duplex and austenitic stainless steels. A ferrite content that is too high or too low can be detrimental. If the ferrite content is too low, then the stainless steel may be susceptible to solidification cracking (hot cracking) upon welding.

Portable hardness testers in contrast to the bench hardness testers, have small sizes, light weight and they are compact devices which measure the hardness by several hardness scales. Usually, the modern portable hardness testers can measure the hardness of all hardness scales.
Hardness testing is used in mechanical and materials engineering to test the hardness of a material, such as a metal. Hardness tests analyze a specific material and its properties and ascertain whether or not a given material is the best fit for the job.
Portable hardness testers are often used for checking flat and round structural pieces in the field. An example of a hardness test of a welding joint could be a Vickers test. Vickers hardness tests use a square pyramid shaped diamond indenter and a load ranging from 1 to 120 kg.

Welder Qualification and Welding Certification Services
Welder certification, (also known as welder qualification) are specially designed tests to determine a welder's skill and ability to deposit sound weld metal. The tests consist of many variables, including the specific welding process, type of metal, thickness, joint design, position, and others. Most often, the test is conducted in accordance with a particular code. The tests can be administered under the auspices of a national or international organization, such as the American Welding Society (AWS), or American Society of Mechanical Engineers (ASME), but manufacturers may specify their own standards and requirements as well.
Once a welder passes a test (or a series of tests) their employer will certify the ability to pass the test, and the limitations or extent they are qualified to weld, as a written document (welder qualification test record, or WQTR).
Our company with professional and experienced international welding engineers & senior inspectors is ready to take welder approval test according to the company procedure or famous codes and standards including:

• ISO 9606
• EN 287
• AWS D1.1
• ASME IX
• API 1104

A roughness tester is used to quickly and accurately determine the surface texture or surface roughness of a material. A roughness tester shows the measured roughness depth (Rz) as well as the mean roughness value (Ra) in micrometers or microns (µm).
With a contact-type roughness meter, surface roughness is measured by tracing the probe across the surface of the target. In contrast, a laser-based non-contact roughness meter emits a laser beam onto the target and detects the reflected light to measure the roughness.
With contact-type surface roughness instruments, a stylus tip makes direct contact with the surface of a sample. The detector tip is equipped with a stylus tip, which traces the surface of the sample and electrically detects the vertial motion of the stylus.
Surface roughness is a component of surface texture and plays an important role in determining how an object will interact with its environment. Roughness is a good indicator of the potential performance of a mechanical component, since irregularities on the surface may form nucleation sites for cracks or corrosion.
