This paper reviews the research conducted by domestic and international welding researchers on developing new welding processes and optimizing welding parameters to address the toughness degradation of high-strength steel welded joints after welding,and analyzes the application characteristics of existing major welding processes in high-strength steel welding.Based on relevant research results,this paper summarizes the latest research advances in gas metal arc welding(GMAW),laser welding,and friction stir welding(FSW)for high-strength steel welding.These advances include:GMAW enhances the strength and toughness of welded joints by controlling welding heat input;laser welding is suitable for thin-sheet high-strength steel welding due to its concentrated energy and minimal welding deformation;the combination of laser and arc heat sources in laser-arc hybrid welding further improves welding efficiency and quality;and optimal matching of stirring tool rotation speed and welding speed is crucial for obtaining high-performance welded joints in FSW.This paper also discusses the development prospects of performance optimization for high-strength steel welded joints,proposing that the field should focus on intelligent welding processes,strengthened numerical simulation for optimizing welding parameters,and the development of high-performance welding materials to explore more welding methods for achieving high-strength and high-toughness joints in high-strength steel.
