    摘要
  • 摘要: 提出超声跨态处理（UPPW）控制激光焊接军机薄壁结构残余应力和变形的新方法.在激光焊接过程中，通过辅加超声振动场，影响激光熔池的形成、流动和凝固等几个关键跨态转变阶段及焊缝的高温超塑性固态相变阶段，达到改善焊缝凝固组织，控制焊接变形，缓释残余应力，提高接头力学性能以及减少裂纹等缺陷的目的.结果表明，UPPW工艺可以显著降低飞机薄壁焊件的残余应力和变形，在合适的工艺参数下，能够使1.5 mm厚TC4航空钛合金薄板焊接件的残余变形降至常规焊接变形量的50%左右，显微组织晶粒度提高约1个级别，且组织形态更加均匀.
    Abstract: A new technology of ultrasonic processing across different phases based on laser welding (UPPW) was proposed to control residual stress and distortion of thin-wall structure in military aircraft. In the process of laser welding, ultrasonic vibration was applied to specimen, by virtue of impact including a few key across state transition phases such as formation, flow and solidification of laser molten pool and stage of high temperature superplastic solid-state phase transformation for welded joints can be affected, the weld solidification organization was improved and joint residual stress was released and joint mechanical properties was improved and deformation was controlled and cracks defects was reduced. Experiments show that the residual stress and distortion of thin-walled structure can be reduced significantly by UPPLW. With the appropriate process parameters, the residual deformation of TC4 titanium alloy with the thickness of 1.5 mm can be reduced by approximately 50% compared with that of the conventional welding and the grain size can be fined by about one level and much more uniform.
