Description

Technical Field

[0001] The utility model relates to the technical field of storage tank processing, in particular to a weld vacuum detection device. Background Art

[0002] In the field of oil storage tank construction, welding is one of the important processes, and its welding quality directly affects the safety of oil storage tanks. Since one side of the tank bottom plate is close to the ground, the bottom plate butt weld can only be welded on one side, and the quality of single-sided welding is worse than that of double-sided welding. Therefore, it is very important to detect the quality of the tank bottom plate weld.

[0003] At present, non-destructive testing methods such as ultrasound, penetration, magnetic powder, and radiography cannot identify the type of welding defects and are insufficient for airtightness inspection. Due to the limitations of working conditions, the commonly used simple and effective weld quality inspection methods such as kerosene inspection, water leak test, and air leak test cannot quickly complete airtightness inspection and are not suitable for tank weld inspection. Therefore, how to quickly and effectively complete tank welding airtightness inspection has become a task that needs to be solved urgently. Utility Model Content
