摘要北京财富中心二期写字楼-4~20层核心筒墙体中间为整体全熔透焊接钢板墙，焊缝集中和大量热输入导致钢板墙焊接过程产生了较大的应力及焊接变形，施工中采取了分段跳焊、对称焊接、严格控制焊接顺序、设置变形控制工艺梁、预留焊接收缩量等工艺，制作了可重复使用的焊接挂架，基本解决了焊接变形过大的问题。

Abstract： In Beijing Fortune Plaza Phase II office building project, the core-tube wall on -4 to 20 floors is all-welded steel wall. Concentration of welds and huge heat input cause relatively big stress and obvious welding deformations during welding of the steel plate wall. Therefore, skip block welding, symmetry welding, strict control of welding sequence, setting of deformation control beam and reservation of welding shrinkage allowance are adopted during the construction and reusable welding manipulator is fabricated to basically avoid excessive welding deformation during construction.

Key words： all-welded steel plate wall welding deformation control welding manipulator
