摘　　要：对于低合金钢的焊接修复来讲,焊后常要采用焊后热处理来恢复材料的冶金和力学性能,焊后热处理不仅耗时较长成本高,并且当代工业设备的结构复杂性、现场的工作条件也限制了焊后热处理的使用,同时焊后热处理也可能对母材造成消极的影响。回火焊道焊接技术作为常规修复手段的新型焊接修复技术越来越受到国外企业的青睐。回火焊道焊接技术无需焊后热处理,利用层道间的焊接热循环作用达到焊后热处理的效果。文中针对回火焊道焊接技术的基本原理进行了介绍,对其发展形式以及研究现状进行论述的同时也对回火焊道焊接技术的发展提出了一些展望。Temper bead welding technology is becoming a routine means of new welding repair technology in foreign firms.It replaces routine post welding heat treatment by using welding thermal cycles between layers as the post-weld heat treatment.In this paper the basic principles for tempering bead welding techniques were introduced,and some prospect on the development of temper bead welding technology were also being put forward.
