摘　　要：大连国际会议中心工程弯扭钢柱加工通过开发特殊的板材弯扭加工胎具,采用单点下压、持续加压、先急后缓、循序渐进、分阶段进行的压型方式,实现板材弯扭成型;通过试拼组立、机械配合火焰矫形,优化焊接顺序,采取焊枪加长、翼缘板分段以及相邻安装段拼接位置预留后焊开腹板等措施,最终保证了弯扭幕墙钢柱的成型效果。During processing of bent and twisted steel columns in Dalian International Conference Center project, plates are bent, twisted and formed through development of special mold for bending and twisting of plates and the forming method of pressing on single point, continuous application of pressure, decrease of pressure applying speed and gradual in-segment processing; welding sequence is optimized through trial assembly and erection and shape correction with combination of mechanical force and flame. The forming effect of bent and twisted curtain wall steel column is guaranteed by the following measures, such as lengthening of welding torch, division of flange plate and post-welded web plate is reserved at position for assembly of adjacent installation segments.
