This content provides you with a example Radiographic Testing Procedure. This is a general and sample RT procedure and you need to modify it to meet your project specifications. SCOPE: This Procedure describes the general requirements for radiography examination (RT) according to related approved weld map for the metallic welding and casting as may be required by…
Introduction Nondestructive material testing with ultrasonics is more than 40 years old. From the very first examinations, using ultrasonic oscillations for detection of flaws in different materials, it has become a classical test method based on measurements with due regard to all the important influencing factors. Today it is expected that ultrasonic testing, supported by great advances in…
This a sample UT procedure and you need to modify it to meet your project specification. Scope 1.1-This procedure describes the general requirements for Ultrasonic examination of metallic welding according related approved weld maps as may be required by the specification or under .which component is being designed and manufactured. 1.2- This procedure provides the…
Magnetic particle examination (MT) is a very popular, low-cost method to perform nondestructive examination (NDE) of ferromagnetic material. Ferromagnetic is defined in ASME Section V as “a term applied to materials that can be magnetized or strongly attracted by a magnetic field.” MT is an NDE method that checks for surface discontinuities but can also reveal discontinuities…
Basic Processing Steps of a Liquid Penetrant Inspection Surface Preparation: One of the most critical steps of a liquid penetrant inspection is the surface preparation. The surface must be free of oil, grease, water, or other contaminants that may prevent penetrant from entering flaws. The sample may also require etching if mechanical operations such as…
Most countries have one or more organizations (“standards bodies”) that develop and publish technical industrial standards. Some don’t, and those usually reference existing codes and standards for their manufacturing, fabrication and construction projects. In the United States, these organizations are usually independent organizations from private industry, but in many countries they are government agencies. The…
Codes, regulatory requirements, standards, specifications and recommended practices are used in all aspects of construction, fabrication, manufacturing and inspection. The following is a brief description of each of these categories along with examples of how they are used. Codes Codes are generally the top-tier documents, providing a set of rules that specify the minimum acceptable…
Non-destructive testing (NDT) is a wide group of analysis techniques used in science and technology industry to evaluate the properties of a material, component or system without causing damage. The terms Nondestructive examination (NDE), Nondestructive inspection (NDI), and Nondestructive evaluation(NDE) are also commonly used to describe this technology. Because NDT does not permanently alter the article being inspected, it is a…
Eddy current inspection is used in a variety of industries to find defects and make measurements. One of the primary uses of eddy current testing is for defect detection when the nature of the defect is well understood. In general, the technique is used to inspect a relatively small area and the probe design and…
