Causes of welding deformation of GB/T1591 Q345C I beam

Aug 20, 2018 · The fundamental cause of GB/T1591 Q345C I beam steel welding deformation is the inhomogeneity of welding heat field. During welding, the high temperature region of the GB/T1591 Q345C I beam steel produces compression plastic deformation, and the shrinkage of this part is prevented by other parts after welding, so the GB/T1591 Q345C I beam steel produces welding residual stress and China Q345b/C Steel Sheet/GB/T 1591-2008 - China H Beam China Q345b/C Steel Sheet/GB/T 1591-2008, Find details about China Steel Plate, Hot Rolled Coil from Q345b/C Steel Sheet/GB/T 1591-2008 - Laiwu Royal Trade Co., Ltd.
