The welding performance of GB/T 1591 Q345D steel plates

The welding of GB/T 1591 Q345D steel plate needs preheating first under some conditions, because the carbon content of Q345D steel is high. The purpose of Q345D steel plates preheating is to prevent cold cracks. The cold crack is directly related to the carbon equivalent.
