| 摘 要： | 火力发电厂环保脱硫系统中烟气加热器（GGH）扇形仓转子的安装尺寸精度要求非常严格。为确保焊制后的各项指标在受控范围内。焊接变形控制十分重要，为此。提出了焊接前应确定合理的焊接顺序。并采用对称焊、先焊短焊缝等以减少焊后残余应力与变形的措施。

| Abstract: | The installing dimensions of gas-gas heater (GGH)rotors in desulphurization systems of thermal power plants are exacting.In order to keep post-welding indices under control,the control on welding deformation is of vital importance.It is suggested that rational welding sequence should be determined before welding,balanced welding be adopted and priority be given to short seams,so as to reduce post-welding residual stress and deformation. |
