Advantages and Limitations of Radiographic Testing 1. There is a direct record of the test results-negatives Because the information recorded on the film is very rich and can be preserved for a long time, radiography becomes a kind of real, direct and traceable detection method. 2. The projection image of defect can be obtained, and the defect qualitative and quantitative is accurate. Among all kinds of nondestructive testing methods, the relative defect qualitative and quantitative is standard. In quantitative terms, the length and width of volumetric defects (pores, slag inclusions) are also accurately determined, with an error of approximately zero mm. However, for area defects (such as cracks, non-fusion) , such as the size of defect tip (height and width of opening) is very small, the image extension on the film may be indistinguishable, and the quantitative data will be small. 3. The detection rate of volume defects is very […]
Four Best NDT Methods for Corrosion under Thermal Insulation Four Best NDT Methods for Corrosion under Thermal Insulation – It has been proved by many literatures and data that Cui is a very common and complicated phenomenon, and it is very difficult to find this kind of corrosion, and it needs a lot of time and economic cost. The corrosion under insulation layer is the corrosion phenomenon of pipeline or equipment covered by insulation layer due to the entry of water and corrosive substances. This corrosion is usually hard to detect because it is usually hidden under an insulating layer, traditionally detected by: Remove pipe surface coverings; Check the pipes; Restore the original appearance of the surface coverings. This process involves a lot of cost and logistical issues. Even cutting the cladding alone is a very time-consuming and labour-intensive process, which may be further complicated if the covering material contains […]
The Necessity of Ultrasonic Testing in Welding of Metallic Materials The Necessity of Using Ultrasonic Testing in Welding of Metallic Materials – There are many problems in the welding process of metal materials, the most important of which are three aspects: internal defects, macro defects, micro defects. In order to better analyze the importance of using ultrasonic nondestructive testing, we first look at these three aspects of defects in detail. Internal defects in welding of metallic materials The internal defects of the welding structure of metal materials are: slag residue left in the weld during workpiece welding, and one is in the process of material welding. A hole formed by encasing a gas in molten metal. Another is in the workpiece welding process between the material and the formation of cracks. Macroscopic defects in welding of metallic materials The macroscopic defects of the welding structure of metallic materials are: the […]
NDT Test Timing of Heat Treatment Status NDT Test Timing of Heat Treatment Status – Many standards require that the timing of NDT testing be performed after heat treatment. Here are 4 common“Fires” for heat treatment. Annealing: The steel work piece is heated to 30-50 ° C above AC3 and held for a period of time to homogenize the austenite structure and refine the grains, followed by slow cooling in the furnace (or buried in sand or lime) to below 500 ° C, a heat treatment process in which air is cooled to room temperature. It can eliminate the defects of coarse structure, ferrite or carbide, composition segregation and internal stress in the workpiece during hot working. Normaliz: A heat treatment process in which a steel workpiece is heated to a suitable temperature above the critical point AC3 or ACCM for a certain period of time to achieve full austenization […]
High Carbon Steel Welding Defects and Preventive Measures As high carbon steel tends to be hardened, it is easy to appear hot and cold cracks during welding. Measures to prevent thermal cracking Control the chemical composition of the weld, strictly control the content of sulfur and phosphorus, increase the content of manganese, in order to improve the weld structure and reduce segregation. Control the cross-section shape of the weld, width-depth ratio is slightly larger to avoid segregation of the weld center. Suitable welding parameters, welding sequence and welding direction should be selected for high rigidity welding parts. When necessary, take pre-heating and slow cooling measures to prevent the formation of hot cracks. Improve the alkalinity of electrode or flux, in order to reduce the impurity content in the weld, improve the segregation degree. Prevention of cold cracking Preheating before welding and cooling after welding can not only reduce the hardness […]

Causes of Lamellar Tearing and How to Prevent? According to the location of lamellar tearing, there are three general categories: The first one is lamellar tearing induced by cold crack at weld toe or root in haz. The second is the heat-affected zone along the inclusion cracks, is the most common engineering layered tearing. The third type of matrix crack far away from the heat-affected zone (haz) usually occurs in the thick plate structure with more MNS. The morphology of lamellar tear is closely related to the type, shape, distribution and location of inclusions. When the MNS inclusions are mainly lamellar along the rolling direction, the lamellar tear has clear step shape, when the MNS inclusions are mainly silicate inclusions, the lamellar tear has linear shape, and when the Al inclusions are mainly Al inclusions, the lamellar tear has irregular step shape. When welding thick plate structure, especially t-joint and […]
NDT – Magnetic Testing (MT) / Magnetic Particle Inspection (MPI) for Pressure Vessel NDT – Magnetic Testing (MT) / Magnetic Particle Inspection (MPI) is widely used in nondestructive testing of pressure vessels. The testing methods are as follows: 1. Magnetic particle testing is another important method for detecting surface defects such as cracks in steel materials. The principle is: the magnetic field will be applied to the specimen, steel and other strong magnetic materials can be strongly magnetized by the magnetic field. If there is a crack on the specimen, and the direction of the crack and the direction of magnetization is right angle, then the magnetic pole appears at the crack, and magnetic leakage field is produced. When fine particles of magnetic particles enter the leakage field, they are attracted and left behind. Because the leakage magnetic field is wider than the crack, the accumulated magnetic powder can be […]
What are the Welding Appearance Inspection Items? Weld is the bonding part of a welded piece. Weld can be generally divided into: flat weld, fillet weld, one-sided weld, one-sided weld double-sided shaped weld. The welds can also be divided into butt welds and fillet welds according to their own cross-sectional forms. Butt Welds: no penetration of the butt welds stress is very small, there is a serious stress concentration, penetration of the butt welds referred to as the butt welds. Fillet Weld: the connection plate edge need not finish processing, plate seamless, weld metal directly filled in the two pieces of welding form right angle or bevel in the region. The Weld appearance inspection can guide welders and welding inspectors to ensure the whole work and project welding quality. Welding appearance inspection items 1.

Analysis of the Types and Basic Characteristics of Welding Cracks With the development of steel, petrochemical industry, ship and electric power industry, the welding structure tends to be large-scale, large-capacity and high-parameter, some also work in low temperature, cryogenic, corrosive media and other environments. Therefore, all kinds of low-alloy high-strength steel, medium and high-alloy steel, super-strength steel, as well as a variety of alloy materials are increasingly widely used. However, with the application of these steels and alloys, there are many new problems in welding production, and the most common and serious one is welding crack. Cracks sometimes occur during welding, sometimes during placement or operation, and so-called delayed cracks. Because this kind of crack can not be detected in the manufacture, the harm of this kind of crack is more serious. There are many kinds of cracks in welding process. According to the present research, according to the nature […]
What is it Incomplete Penetration? Incomplete Penetration during welding refers to the defect caused by no melting between the base metal and the weld metal does not enter the root of the joint. According to the welding method of welding parts, it can be mostly divided into root and middle Incomplete Penetration. The root is not welded because the liquid weld metal does not enter the blunt edge of the root, most of them exist in the single side welding of the V-shaped or U-shaped groove, the middle is because the liquid metal does not enter the middle blunt edge, most of them exist in the double V or double U-sided welding. The existence of Incomplete Penetration in the weld will reduce the effective area, and seriously cause the mechanical properties of the decrease such as the strength of the welding parts. Incomplete Penetration will also cause stress concentration and […]

Common Crack Types of Pressure Vessels and Pipelines and their NDT Techniques Common crack types of pressure vessels and pipelines: Stress corrosion cracking Stress corrosion crack is a common type of crack, which is related to the interaction of internal and external stress and corrosion medium. Common in the boiler steam pipe and container seat, mainly tied in the pipeline outside. According to the research, because of the influence of hot water medium on the pipeline itself, the pipeline is easy to be corroded by hot water after long-term operation, and the flowing water medium has certain pressure. When the pressure on the outer surface of the pipeline exceeds the stress limit of the region, it will inevitably lead to the external deformation and cracking of the pressure pipeline. Mechanical Fatigue Crack Mechanical fatigue cracks are common in rotating machinery parts such as impeller, blade and shaft in boiler auxiliary […]

JSC is an ISO 17025 NDT Lab / Company (CNAS) ISO/IEC 17025:2017 is an international standard specifying requirements for quality and competence in testing and calibration laboratories. The standard requires that such labs prioritise excellent quality practices and develop a reliable quality management system to establish and demonstrate their competence. The full standard is called ISO/IEC 17025, since the certification was created by the International Organization for Standardization in conjunction with the International Electrotechnical Commission. However, many shorten this to ISO 17025 or simply 17025 certification when referring to the standard. Ultimately, ISO 17025 is for any organization that performs testing, sampling or calibration and wants to be sure of the reliability of their results. The simplest way we can put it: if you work in a testing environment that produces measurable results, then ISO 17025 is probably applicable. This may even mean you don’t necessarily call your facility a […]
What are the Ultrasonic Testing (UT) Methods? Ultrasonic Testing (UT) Methods – Sound is a physical phenomenon, although its instantaneous existence is very obvious, but it does not cause any permanent changes. This is why sound (low energy) is ideal for nondestructive testing, where the state of the object under test is determined by obtaining accurate information. For this purpose, a method is needed that produces a definite reaction within the subject without changing its state. “Passivity” is the most important feature that sound is required for material testing. 1. Passive acoustics is also used in the special field of acoustic emission, in which sound waves are generated internally by spontaneous changes in material conditions. Sound waves are mechanical waves and therefore need to act as a medium for conducting them. Whether it is a solid, a liquid, or a gas, each material can be evaluated for its particular effects […]

How to Explain the Cause of the Welding Defects on the Negative Plate 1. Common welding defects can be classified into four categories: 1) Weld size does not meet the requirements: such as ultra-high, ultra-wide, too narrow, too large difference between height and height, weld transition to the base metal is not smooth. 2) Welding surface defects: such as undercut, Weld, concave, overflowing, no penetration, surface porosity, surface cracks, etc. . 3) Weld internal defects: such as porosity, slag inclusion, cracks, non-fusion, tungsten inclusion, double-sided welding, such as the lack of penetration。 4) The properties of welded joint do not meet the requirements: the mechanical properties and corrosion resistance of welded joint are reduced because of over-heating and over-burning. 2. The damage of welding defects to welded components mainly includes the following aspects: 1) Cause stress concentration The distribution of stress in welded joint is very complex. Where there is […]
Welding defects refer to various discontinuities, imperfections, or poor connections in the welded joint that occur during the welding process. These defects can include incomplete fusion, porosity, slag inclusion, undercut, overlap, burn-through, segregation, incomplete filling, and welding cracks, among others. Among these defects, welding cracks and porosity pose the greatest hazards to the performance and safety of welded structures. Welding cracks are gaps that form in the welded joint due to the breakdown of the atomic bonds between metals, caused by welding stresses and other brittleness-inducing factors. Depending on their nature, welding cracks can be classified into various types such as hot cracks, cold cracks, reheat cracks, lamellar tearing, and stress corrosion cracks. For example, hot cracks occur at high temperatures during the welding process. Their shape and temperature zone vary depending […]
Post-weld Heat Treatment is not Entirely Advantageous Post-weld heat treatment – Welding residual stress is caused by non-uniform temperature distribution, thermal expansion and contraction of weld metal, so it is inevitable to produce residual stress with welding construction. The most common method to eliminate residual stress is high-temperature tempering, in which the weldments are heated to a certain temperature and held for a certain time in a heat treatment furnace, taking advantage of the reduction of the yield limit of the material at high temperature, when the internal stress is high, the plastic flow will occur, the elastic deformation will decrease, and the plastic deformation will increase and the stress will decrease. 1) Selection of heat treatment methods The influence of post-weld heat treatment on tensile strength and creep limit of metal is related to the temperature and holding time of heat treatment. The effect of post-weld heat treatment on […]
Why porosity / porosities often appear in welds? Reason 1: The gas is impure Porosity – Preventive measures: gas cylinders regularly clean, in the use of gas cylinders inverted 1-2 hours before opening the valve after the water after use. Reason 2: Surface Oil and rust Preventive measures: cleaning the surface of the workpiece before welding oil, rust, oxide, etc. . Can be used wire brush, shot blasting and other methods to remove. Reason 3: Blocked air passage or air leak Preventive measures: often check the gas system is blocked or gas leakage. Timely cleaning, maintenance or replacement, develop good operating habits. Reason 4: Seal weld without vent hole Prevention measures: butt welding will increase chamfer, the middle does not leave air gap. Leave out part of the weld without welding or until the workpiece cools before welding. Reason 5: Welding Torch angle is too small, air from the rear […]
