摘要:
窄间隙焊接技术具有焊缝金属填充量少、焊缝金属和热影响区的组织明显细化，焊接变形及残余应力小等优点，但其在工业使用阶段仍旧存在不足。针对由于设备功率限制，导致的窄间隙焊接技术的焊接热敷效率及熔深不能满足现代工业生产需求的问题，指出了热丝焊接技术和窄间隙焊接技术相结合可以有效的弥补窄间隙焊接技术中存在的不足，同时分析了热丝窄间隙焊接技术在弧焊和激光焊中的研究现状，并指出该技术在这两种焊接中的优越性，为进一步研究和工业化应用提供了引导。
Abstract:
Narrow gap welding technology possesses some advantages, such as low weld metal filling amount, the organization of weld metal and heat affected zone obviously refined, small welding deformation and residual stress and so on, but some insufficient still exist in industrial usage stage.  For the equipment power limitation, which leads to the narrow gap welding heat efficiency and penetration can’t meet the demand of modern industrial production, it pointed out the combination of hot wire welding technology and narrow gap welding technology can effectively make up for the insufficient of narrow gap welding technology, analyzed the research status of hot wire narrow gap welding technology in arc welding and laser welding, and pointed out the advantages of this technology in these two kinds of welding, which provides a guide for further research and industrial application.
