Thermal analysis is one of the cardinal studies essential for arc welding processes. Thermal
field and temperature distribution in arc welds affect the quality of welds as they govern the …

An automated radiographic NDT system for weld inspection has been developed. The entire
system consists of two major components: weld extraction and flaw detection. Part I of the …

Automated inspection of surface defects is beneficial for casting product manufacturers in
terms of inspection cost and time, which ultimately affect overall business performance …

In order to detect weld defects in steel tube, a real-time imaging and detecting system is
setup. In the extracted weld seam, based on spatial characteristics near defects—variance …

This paper describes a real-time radiography configuration for the automatic inspection of
welds. The optimal geometrical imaging configuration is evaluated and discussed in relation …

Manual interpretation of radiographic weld images is subjective, inconsistent, labor
intensive, and sometimes biased. This paper presents a welding flaw detection methodology …

为了检测X 射线探伤图像中螺旋钢管焊缝缺陷, 提出了一种新的实时自动检测算法.
它是一种基于图像空间特性(空间对比度与空间方差) 的模糊识别算法, 与人眼视觉识别特性相近 …

Condition monitoring and fault diagnosis are the most important process in manufacturing
industries. In this paper, a steel beam panoramic crack detection method based on …

Based on the experimental non-linear time series of welding current produced by Square
Wave Alternating Current Submerged Arc Welding (SW AC SAW) at different frequency and …

Automatic defect detection in X-ray images is currently a focus of much research at home
and abroad. The technology requires computerized image processing, image analysis, and …
