However, because the through hole is often provided with a T-shaped plate, that is, the through hole has a built-in type plate, so that when the sealing plate seals the through hole, there is not only a welding seam with the hull part, but also a weld between the sealing plate and the type plate. The weld structure is complex. At present, the airtightness test of the sealing plate weld at the through hole is usually carried out by the fillet weld impact test. The failure of the performance test will affect the inability to paint the later products, affect the integrity of the paint, and affect the suppression of the entire cabin.
