What is Radiographic Quality in Welding?

Radiographic quality in welding is the soundness of a weld that shows no internal or under bead cracks, voids, or inclusions when inspected by X-ray or gamma ray techniques. Radiographic quality welds are free of these kinds of imperfections and considered to be high-quality welds. In order to achieve radiographic quality, welders must follow specific welding procedures and use the appropriate welding techniques.

Radiographic quality welds are important for a number of reasons:

  1. First, they ensure the safety of any structure or device that will be using the weld.
  2. Second, radiographic quality welds are required for many critical applications, such as in the aerospace and nuclear industries.
  3. Finally, radiographic quality welds can improve the overall performance of a structure or device.

Factors that can affect the radiographic quality

There are a number of factors that can affect the radiographic quality of a weld. These include:

  • the type of metal being welded,
  • the welding process used,
  • the skill of the welder,
  • and the quality of the welding equipment.

In order to ensure radiographic quality, it is important to carefully control all of these factors.

What is radiographic inspection used for?

Radiographic inspection is a non-destructive testing (NDT) method that uses X-rays or gamma rays to examine the internal structure of a component or device. This type of inspection can be used to detect a variety of defects, such as:

  • cracks,
  • voids,
  • inclusions,
  • and porosity.

How is radiography used in welding testing?

Radiography is commonly used to inspect welds for defects. In order to do this, a radiographic film is placed on one side of the weld. X-rays or gamma rays are then passed through the weld and onto the film. The film is then developed and examined for any defects.

What are some common radiographic quality problems?

Some of the most common radiographic quality problems include:

  • under bead cracking,
  • lack of fusion,
  • incomplete penetration,
  • and slag inclusions.

These types of defects can reduce the strength and integrity of a weld.

What is radiography in pipeline?

Radiography is a non-destructive testing (NDT) method that uses X-rays or gamma rays to examine the internal structure of a component or device.

Welding radiography salary

The average salary for a welding radiographer is $85,000 per year.
