Problems solved by technology
[0005] In the above welding method, when a plurality of ribs are inserted into the grooves of the upper end plate and the lower base plate, relative movement may occur between the upper end plate and the lower base plate, resulting in the simultaneous movement between the upper end plate and the lower base plate. Axis cannot be guaranteed
At the same time, in the process of welding and fixing multiple ribs to the upper end plate and the lower base plate, the upper end plate and the lower base plate are prone to deformation, and the flatness of the upper end plate and the lower base plate cannot be guaranteed
And once the deformation occurs, the parts cannot be corrected and can only be scrapped, resulting in low manufacturing efficiency of the end cover parts
