Welding X Ray Defects. The first method of radiographic testing uses X-rays produced by an X-ray tube that can accelerate electrons or through the K-shell-emission technique which helps in manipulating the electrons in their atomic shells. There are two methods of radiographic testing to visualize welds and welding defects such as X-ray RT and Gamma rays RT based on the radiation source.
VT Visual Inspection. I will talk briefly on each of them. TYPES OF WELD FLAWS.
Incomplete fusion LF Incomplete fusion or lack of fusion is a condition where the weld filler metal does not properly fuse with the base metal.
2019 A Welding Defect Identification Approach in X-ray Images Based on Deep Convolutional Neural Networks. Incomplete root fusion is when the weld fails to fuse one side of the joint in the root. The experimental results show that the X-ray weld defect classification algorithm based on SVM and LE has higher recognition precision and its average classification accuracy is 93. Incomplete fusion LF Incomplete fusion or lack of fusion is a condition where the weld filler metal does not properly fuse with the base metal.
