What is the reason for the deformation of the welding seam of the oil storage tank
Jun 15, 2021

Deformation of the welding seam of the oil storage tank is a common quality problem in the actual use of the oil storage tank, which easily causes the tank body to leak and affects the safety of the oil storage tank. The welding seam deformation of the oil storage tank is mainly caused by the lack of a reserved welding seam gap and irregular operation. The reasons for the welding seam deformation of the oil storage tank are listed and analyzed in detail below.

1. 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.

2. Due to irregular welding operations of oil storage tanks, there are many weld deformations during the construction process. Before specific operations, most construction units have formulated relatively complete construction plans and set up special welding process instructions, but the operators have not fully performed welding in accordance with various process guidance requirements and construction specifications, resulting in certain quality problem occurrences of oil storage tanks.
