| 摘 要： | 本文对２０ＣｒＭｏ＋３５ＣｒＭｏ空心抽油杆摩擦焊接头采用局部中频感应加热回火热处理工艺，通过对摩擦焊接及焊后回火热处理工艺的优化，提高了接头的强韧性，使焊缝区的σｂ、σｓ超过了ＳＹ５５５０－９２空心抽油杆规定的Ｄ级杆的标准要求。文中对摩擦焊接头的组织、晶粒度和硬度分布进行了分析，并对回火后近缝区的组织变化进行了研究。

| Abstract: | A local tempering treatment by mid-frequency induction heating is used for friction welding joints of 20CrMo+35CrMo hollow sucker rods. Through the optimizations of both friction welding proces sing and postweld tempering treatment, the strength and toughness of the joints are increased and σ b and σ s of weld zone are beyond those required for class D in the Standard SY5550-92 Hollow Sucker Rod. Analyses of the microstructure, gain size and hardness distribution of friction welded joints are given and the variation in microstructures near weld zone after tempered are studied. |
