摘　　要：针对大型焊接实腹式工字型吊车梁建造工作量大、变形控制困难的特点,结合国家规范要求和施工现场实际情况,关键抓好控制建造变形和焊接质量两方面工作,具体实施上采取滚压、预变性、对称变形、火焰矫形以及控制焊接条件等技术措施,有效地保证了工程施工质量及满足了验收要求。In view of the large solid welding I-shaped crane beam construction workload, difficult to control the deformation characteristics, combined with the requirements of national standard and the actual situation of the construction site, the key to the construction quality control and welding deformation and the two aspects of the work, the specific implementation by rolling, denaturing, symmetrical deformation, flame straightening and welding conditions and technical measures. To effectively ensure the construction quality and meet the acceptance requirements.
