Introduction The result of visual strength grading is the attribution of indicative values or allowable stress levels, for prediction of key properties, which allow for the mechanical characterization of the material.
This allowed to obtain the mechanical properties related to the material itself and its defects rather than to the state of conservation.

Therefore, the control of mechanical properties of HAZs is a key for the manufacture of heavy thickness welding steel pipes.

The RS theory is a mathematical theory for dealing with fuzzy and uncertain knowledge, and is one of the hot spots in information science, and has been widely used in the fields of medicine, materials science, mechanics, management science and other fields.
Cases In the process of the actual engineering operation, the failures of single line fault in power distribution network is 70%~80% of total faults in probability, so this paper only carries simulation on an assumed single fault.

It is a very widely practiced welding process to join materials. known as shielded metal-arc welding process.
Being a fusion welding process, the heat input during welding affects the base material both physically and metallurgically.
The plates are kept in the oven for three hours so that uniform heat penetration into the material takes place.
