| 摘 要： | 浮顶储罐的浮舱顶板是整个罐体中厚度最薄的部位，也是储罐焊接施工中最易产生焊接变形的部位。浮舱顶板的焊接变形与浮顶的结构、组装、焊接顺序及焊接工艺方法等相关。由于浮舱顶结构较复杂，其焊接顺序与罐底幅板的焊接顺序有较大差别的。防止浮舱顶板的焊接变形应从结构设计、组装顺序、焊接顺序、焊接工艺等方面着手。对已产生的变形，应选择正确的方法进行校正和补救。

| Abstract: | Top board of buoyancy module of floating roof tank is the thinnest part in the whole tank body as well as the part which is the most liable to welding deformation in welding operation.The welding deformation of top board of buoyancy module is related to floating roof structure,installation,welding sequence and welding technology.Because of more complicated structure,the welding sequence of buoyancy module roof is very different from that of tank bottom board.Prevention against the welding deformation of top board of buoyancy module should be started from structural design,installation sequence,welding sequence and welding technology.The deformation should be corrected and repaired in right ways. |
