How to do radiographic testing (RT)?

What is radiographic testing(RT)?

Radiographic testing(RT or X-ray or Gamma ray)is a non-destructive testing (NDT) method that involves the use of either x-rays or gamma rays to view the internal structure of a component.Radiographic testing is often used for the weld detection of pipeline products,such as weld of steel pipe,elbow,tee,flange etc.The obvious advantage of the X-ray method is that it can help establish the internal integrity of the weld without damaging the welded parts.

Radiography (X-ray) uses X-rays and gamma-rays to produce a radiograph of a specimen,showing any changes in thickness, defects (internal and external),and assembly details to ensure optimum quality in your operation.

RT usually is suitable for testing welded joints that can be accessed from both sides, with the exception of double-wall signal image techniques used on some pipe. Although this is a slow and expensive NDT method,it is a dependable way to detect porosity,inclusions,cracks,and voids in weld interiors.

Advantage of radiography testing:

Compared to other nondestructive testing methods,radiography has several advantages.It is highly reproducible,can be used on a variety of materials,and the data gathered can be stored for later analysis.Radiography is an effective tool that requires very little surface preparation.Moreover,many radiographic systems are portable,which allows for use in the field and at elevated positions.
