Research on Multi-layer & Multi-pass Welding Processes Domestically and Internationally
Current Research Status of Multi-layer and Multi-pass Welding Processes Research on multi-layer and multi-pass welding processes, both domestically and internationally, primarily focuses on welding residual stress, with an emphasis on predicting and eliminating residual stress distribution post-welding. Research methods can be categorized into two approaches: experimental research and numerical simulation. Heat treatment is commonly used to eliminate residual stress after welding. However, due to...
