Column Cross Process characteristics: Cross post material due to its main planks are cross-pillar, so before assembling and welding the main material of the puzzle elements to note preheat to prevent weld defects. Large cross member penetration column machining, welding deformation and therefore larger. Flange width is narrow, distortion correction more difficult flap. Cross cylindrical member overall contraction stress caused by welding the welding deformation of large cross-column plant, and more difficult to correct the distortion. Cross post material due to its main planks are, therefore before the main assembly and welding materials and components to note puzzle preheat to prevent weld defects. Cross post processing: Loft, No. material. Steel tape must be cross-checked by the measurement department column price labels before use and correction values, the standard scale for measuring the tension when L≤30m 5kg, in order to ensure that crossed, fabrication and site installation with a ruler consistency.
