  • Deformation of the welding seam of the well casing is a common quality problem during the actual use of the well casing, which easily causes the tank body to leak and affects the safety of the oil storage tank. The welding seam deformation of the well casing 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.
