AI Technical Summary

Technical Problem

Poor welding of sealing plates in existing containers is prone to occur, affecting the quality of the containers. Existing technologies have not been able to effectively solve the problem of poor welding between sealing plates and corner posts and extensions.

Method used

By setting the area of the sealing plate to be greater than or equal to the area of the gap, the deformation of the inner side of the corner post and the extension is covered, reducing the gap between the sealing plate and the inner side and the outer side wall of the extension. The upper and lower cover plates are respectively placed on the upper and lower deformation areas to ensure effective welding of the sealing plate to the corner post and the extension.

Benefits of technology

It improved the welding quality of the sealing plate, reduced welding defects, increased production efficiency, and adapted to structural changes caused by size differences.
