摘　　要：随着我国《中国制造2025》战略实施,焊接制造领域经过"两化"融合的推动,正朝数字化、信息化、智能化制造转型,进而使焊接制造过程的信息需求量显著增加。围绕上海交通大学智能化焊接与材料精密制造研究所近年来在智能化焊接领域所取得的成果和关键技术应用等展开讨论,内容涉及基于视觉传感的焊接路径自主导引与规划、焊接动态过程液态熔池的智能表征和基于视觉传感的焊接全场高温应变的在线测量及多尺度计算。上述研究成果的工程应用,一定程度上丰富和发展了焊接智能化技术领域的内涵。期望展示的焊接视觉智能化传感研究成果为焊接智能制造的发展抛砖引玉。With the implementation of China Manufacturing 2025,wehling manufacturing has been developed towards the digitization, informatization and intelligentization. Thus,the demand tor information in wehling process is significantly increasing. In this paper,we introduce some new research works and key technologies on intelligent welding field in the Institute of Intelligent Welding ＆ Materials Precise Processing. The main research include：the research on autonomous guidance and welding path planning based on visual sensor, intelligent characterization of dynamic liquid wehting pool,in-situ the measurement and multiscale calculation of the high temperature strain during welding process. The application of the above research development,to a certain,enrich and develop the connotation of intelligent welding technologies. It is expected that the results of intelligent visual technologies will be the beginning of welding intelligent manufacturing development.
