Radiography test for welding pdf
Radiographic and ultrasonic weld inspection are the two most common nondestructive testing (NDT) methods used to detect discontinuities within the internal structure of welds. The obvious advantage of both of these testing methods is their ability to help establish the weld’s internal integrity without destroying the welded component.

radiographic test (RT) temper beads tensile tests ultrasonic testing (UT) visual test (VT) X-rays Introduction Quality control is used throughout the welding industry to monitor the quality of the items produced. All manufactured items are made to speciﬁcations. Inspections must be made during and after the manufac-turing cycle to ensure that parts meet the requirements of the
Radiographic test-ing processes commonly involve the use of X-rays or gamma-emitting materials to produce highly detailed images for inspection. The benefits of employing industrial radiography in crucial testing environments are numerous while the risks involved for personnel require careful consideration. The acts of minimizing risk and promoting calculated safety measures ensure that
Abstract. This test method provides a uniform procedure for radiographic examination of weldments using industrial radiographic film. Requirements expressed in this method are intended to control the quality of the radiographic images and are not intended for controlling acceptability or quality of welds.

Radiographic Testing Radiography is used in a very wide range of aplications including medicine, engineering, forensics, security, etc. In NDT, radiography is one of the most important and widely used methods. Radiographic testing (RT) offers a number of advantages over other NDT methods, however, one of its major disadvantages is the health risk associated with the radiation. In general, RT
Radiation from the source passing through any defects in the component under test is less attenuated than adjacent rays through unflawed metal and so darkens the film more. 2.2 Application of Radiographic Methods in Practice 2.2.1 Source Type Industrial radiography typically uses photographic film to record the two-dimensional x-ray or gamma ray transmission profile through the …

X-radiation is produced from a vacuum tube – this contains a cathode which produces a beam of electrons when an electric current is passed, the higher the voltage the more intense is the stream of electrons and the deeper the penetration – see Table 1.
Radiographic Testing (RT) of Deaerator Vessels The purpose of radiography of pressure vessels is to insure the structural integrity of welded joints on the vessel. The amount of radiography used affects the head and shell thickness and the vessel cost. Generally, if more radiographs are taken, thinner materials can be used. This technical paper is meant to be used for informational purposes
Radiograph Interpretation – Castings The major objective of radiographic testing of castings is the disclosure of defects that adversely affect the strength of the product. Castings are a product form that often receive radiographic inspection since many of the defects produced by the casting process are volumetric in nature, and are thus relatively easy to detect with this method.
