摘　　要：大熔深焊接技术作为一种新型的焊接技术,其对于厚板或者中厚板焊接质量的保证和生产效率的提高有着极其重要的意义。因此,制定一套大熔深焊接技术工艺规范,生产相应的焊接设备是从事相关研究工作人员的主要目标。目前大熔深焊接技术主要分为两大类:以激光、电子束为主的高能束深熔焊,以及在传统的气体保护焊基础上升级而来的高效大熔深焊接技术。从应用背景、产生过程以及技术特点等方面综述了这两类大熔深焊接技术的研究进展,为相关研究工作提供一定的参考。As a new welding technology,deep penetration welding technology is of great significance to ensure the welding quality and improve the production efficiency of thick plates or plates.Therefore,it is the main goal of relevant researchers to formulate a set of technical specifications for deep penetration welding and produce corresponding welding equipment.At present,deep penetration welding technology is mainly divided into two categories:high-energy beam deep penetration welding mainly using laser and electron beams,and efficient deep penetration welding technology upgraded from traditional gas shielded welding.The research progress of deep penetration welding technology is summarized from the application background,production process and technical characteristics,which provides certain reference for related research work.
