The properties of different wet welding are introduced at first. And then, the research development and achievements of wet welding are discussed from three aspects, which are welding rod study, arc stability study and welding shape modeling. At last, some suggestions are proposed that we should increase the study on the wet welding special sensors and arc discharging mechanism, and so as to promote high quality development of wet welding. 湿法焊接 焊条 电弧稳定性 焊缝成形 研究进展 wet welding wet welding electrode arc stability welding shape research development TG456.5 江西省教育厅科技项目(GJJ180937);国家自然科学基金项目(51665016) 2022-03-08 9 50
