Microstructural Changes and Impact Toughness of Fill Pass in X80 Steel Weld Metal
Multi-pass welding is used in high-pressure and thick-walled pipes in natural gas and oil pipelines. When a welding layer of a welded joint is subjected to different welding thermal cycles, its microstructure and properties change, thereby affecting the overall welding performance. In this study, th...
