Deformation of the welding seam of the API standard 650 ground supported liquid storage tanks is a common quality problem during the actual use of the API standard 650 ground supported liquid storage tanks, which easily causes the tank body to leak and affects the safety of the oil storage tank. The welding seam deformation of the API standard 650 ground supported liquid storage tanks is mainly caused by the lack of reserved welding seam gap and irregular operation. The oil storage tank has not reserved the corresponding weld gap, resulting in deeper root removal during the front welding activity. The heat output of the weld will increase under the influence of a long time, and the deformation of the weld will gradually become serious.

The ring of API standard 650 ground supported liquid storage tanks annular plates shall have a circular outside circumference, but may have a regular polygonal shape inside the tank shell with the number of sides equal to the number of annular plates. These pieces shall be butt-welded in accordance with API Standard 620 R.7.1.1, Item b. The plates of the first shell course shall be attached to the annular bottom plates by welds as required by API Standard 620 5.9.5 except when a full penetration weld is used or required.
