Hainan Steel teach you: construction steel welding deformation species

Hainan steel welding deformation can be divided into shorter linear, angular deformation, bending deformation, distortion, wavy instability deformation.
Linear shortened: refers to the length shortening and narrowing the width of the weldment deformation caused by shrinkage, divided into longitudinal and transverse shortening shortened.
Angular Distortion: Weld-sectional shape is due to the asymmetry in the thickness direction caused by the deformation generated in the thickness direction.
Wave transformation: a large area sheet welding, including buckling under stress produce leaving the board to become warped wavy deformation.
Distortion: After welding different components and flanges and web inconsistent longitudinal shrinkage deformation along the longitudinal axis value angle member member deformed shape generalization formed. Once produced distortion is difficult to correct. Mainly due to the poor quality of assembly, hold the workpiece is not correct, welding sequence and orientation of improper arrangements, in particular the construction to attract attention. Hainan Special attention deformed steel.
Deformable member and the shape of the structure so that it does not meet the requirements of design drawings and acceptance not only affect the normal process of final assembly, but also may reduce the carrying capacity of the structure. As already generating docking and landing member angular distortion at the time of tension will cause additional moment, which can lead to severe additional stress overload structural damage.
