Three-demention deformation behavior of the Taipei National Enterprise Center (TNEC) excavation case history [J]．Canadian Geotechnical Journal, 2000, 37:438-448.

Welding distortion is a partial plastic deformation from internal stresses caused by non-uniform temperature fields on metal components in welding reach the material yield limit.
All of the above will cause great difficulties for site installation, and will also cost a lot of manpower and material resources to deal with welding distortion once the tolerance occurs.
