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 Channel Specification Suppliers, all Quality Channel Channel Specification, Channel Specification Suppliers Directory - Find variety Channel Specification Suppliers, Manufacturers, Companies from around the World at fresh carrots specification ,long grain white rice specifications ,strut channel, Pumps H Beam,Angle Bar,Channel Steel,T Bar Steel,Flat Bar.
