Measures to prevent GB713 Q370R steel plate cold cracks

GB713 Q370R steel plate is mainly used for the manufacture of pressure bearing medium and low pressure vessels. It has the advantages of good strength and toughness matching, low plate thickness effect and good welding performance. However, compared with the traditional GB713 Q345R steel plate, GB713 Q370R steel plate is easy to produce cold cracks in the welding process, so the analysis of the cold crack formation mechanism in the welding process and how to take effective preventive measures in the construction are the key to ensure the welding quality of the SPHErical tank.GB713 Q370R steel plate is katalor’s main steel.katalor has a long story on supplying GB713 Q370R steel plate.

Measures to prevent GB713 Q370R steel plate cold cracks:

1. reduce the source of hydrogen as far as possible.
2. reduce the source of hydrogen as far as possible.
3. select appropriate post heat temperature and post heat time.
4. Maintaining proper interlayer temperature during welding.
5. using the appropriate line energy.
6. Prevent the strength of the pair.
7. reduce the deformation of the wrong side and angle.
8. reduce the deformation of the wrong side and angle.
