影响钢结构焊接技术进步的几个重要因素 Several important factors affecting welding technology progress of steel structure 戴为志 DAI Weizhi 1 first-author 中国工程建设焊接协会 中国工程建设焊接协会 China Engineering Construction Welding Association China Engineering Construction Welding Association 根据钢结构焊接技术发展的客观规律和过程,结合当前钢结构焊接工程现状,从母材、焊材和设备三个方面——"钢结构大规模采用高强钢,促使我国焊接技术迅速发展""高品质、高性能的焊材是保证焊接技术进步最大支持""新型焊机是焊接技术进步的又一重大支持",分析论证耐候、耐蚀、耐热钢,焊接低强配比,焊材的科研及生产以及快速脉冲压缩电弧等影响焊接技术进步的因素,特别是机器人自动焊技术以及相关工程案例,力图揭示焊接技术的发展方向。 According to the objective law and process of the development of steel structure welding technology, combined with the current situation of steel structure welding engineering, from three aspects of base metal, welding material and equipment-"large scale use of high-strength steel in steel structure promotes the rapid development of China’s welding technology", "high-quality and highperformance welding material is the greatest support to ensure the progress of welding technology", and "the new welding machine is the progress of welding technology". This paper analyzes and demonstrates the factors influencing the progress of welding technology, such as weather resistance and corrosion resistance, heat-resistant steel, low strength ratio of welding, scientific research and production of welding materials and rapid pulse compression arc, especially the robot automatic welding technology and related engineering cases, trying to reveal the development direction of welding technology. 高强钢 机器人自动焊技术 焊接材料 快速脉冲压缩电弧 high strength steel robot automatic welding technology welding materials fast pulse compression arc TG457.11 2022-03-08 9 50
