摘　　要：厚板牵引梁在搅拌摩擦焊焊接过程中,容易发生焊缝表面沟槽、焊缝压深、搅拌头断针等质量问题。通过应用优化组焊压紧工装、焊接参数及搅拌头的使用设计等攻关措施,可有效降低焊接质量问题发生,提升牵引梁焊接效率。During the welding process of thick plate traction beam,it is easy to have quality problems such as groove on the weld surface,deep weld pressure,broken pin of stirring head,etc.During the friction stir welding welding process,the welding quality problems can be effectively reduced and the welding efficiency of traction beam can be improved by optimizing the welding equipment,welding parameters and the design of stirring head.
