2022年12月21日 · X-ray inspection of welds is a non-destructive test method (NDT) used to evaluate the quality and integrity of welded parts. It relies on X-rays or gamma radiations to penetrate weld without destroying them and detect any internal imperfections such as cracks, porosity, or other flaws that may not be visible to the naked eye.

In a radiograph, dark, jagged asymmetrical shapes within the weld or along the weld joint areas are indicative of slag inclusions. Incomplete penetration (IP) or lack of penetration (LOP) occurs when the weld metal fails to penetrate the joint.

2021年8月5日 · How Radiographic Testing Works on Welds? This method of weld testing makes use of X-rays, produced by an X-ray tube, or gamma rays, produced by a radioactive isotope. The basic principle of radiographic inspection of welds is the same as that for medical radiography.

Applied Technical Services performs weld X-ray inspections for a wide range of industries, including aviation, automotive, construction, infrastructure, and maritime. We inspect the quality of welds between metallic surfaces to help verify that they conform to applicable codes and perform safely and reliably.

X-ray welding is an experimental welding process that uses a high powered X-ray source to provide thermal energy required to weld materials. [1] The phrase "X-ray welding" also has an older, unrelated usage in quality control. In this context, an X-ray welder is a tradesperson who consistently welds at such a high proficiency that they rarely ...

We establish the dataset of X-ray image for weld defects called WDXI. WDXI consists of 13,766 X-ray images, including seven significant types of weld defects.

YOLO-Xweld is derived from YOLO v3-tiny by adding an SPP module to the backbone network to enhance multi-scale feature extraction, and weakening large-scale network detection branch based on characteristics of pipeline weld X-ray images.

X-ray inspection is a non-destructive testing method that is frequently used for material testing of weld seams. X-rays or gamma rays are sent through the weld and detected on the other side by a detector. Different thicknesses or densities in the material result in visible differences in the X …

2024年9月24日 · Radiographic weld testing involves the use of X-rays or gamma rays to inspect welds for defects such as cracks, porosity, and inclusions. By passing radiation through the weld and capturing the image on film, inspectors can identify …

2015年12月4日 · Industrial Radiography, or Weld X-ray Inspection, involves gamma radiation sources, most commonly Iridium-192 and Cobalt-60, which are used to inspect a variety of materials. The vast majority of Weld X-ray Testing concerns the testing and grading of welds on pressurized piping, pressure vessels, high-capacity storage containers, pipelines ...
