摘　　要：P006/007风洞项目与常规汽轮机结构差异大,焊缝无损检验和尺寸精度要求都较高,其装焊部套中的框架类、壁板类等结构主体都为焊接工字钢、焊接槽钢,整体尺寸长、刚性差。文章从零件下料、坡口设计及焊接过程控制等方面进行深入探讨和分析,对风洞项目装焊件的焊接变形控制措施进行了阐述。The P006/007 wind tunnel program is different from the conventional turbine structure, it requires high standards about weld non-destructive testing and size precision testing, and claims a structure body of frame or panel of welding die consisting of welded I-beam and welded channel iron which have long size and weak rigidity. Basing on deep discussion and analysis of parts cutting, groove design and welding process, the article descripts some control measures on welding deformation of weldment of wind tunnel program.
