Some defects may be found after the regular safety inspection for the a387 gr22 welding. The common a387 gr22 welding defects are: Tank cracks, tank welding defects. The cracks on the base metal, surface and near surface of the tank wall shall be eliminated by grinding with circular arc, and then magnetic particle inspection or re inspection shall be carried out. Cracks in heat affected zone: generally, grinding method is used to eliminate cracks, and magnetic particle or dye flaw detection is used to confirm that there is no crack, and then repair welding or grinding smooth transition.

The yield point of the steel structure determines the stress that the structure can withstand without permanent deformation. The minimum yield point of typical carbon structural steel is 235MPa. The minimum yield point of typical low-alloy high-strength steel is 345MPa. Therefore, according to the proportional relationship of its yield point, the use of low-alloy high-strength steel allows the stress to be 1.4 times higher than that of carbon structural steel. Compared with a387 gr22 welding, carbon structural steel, the use of low-alloy high-strength steel can reduce the size of structural parts and reduce weight.
