| Summary: | When the waffle panel of AMg6 alloy rolls into the cylindrical shell, a shape defect occurs. Manual
elimination of this defect causes local irregularities on butt welded edges of the waffle shell. This leads
to difficulties in the process of welding by friction welding with mixing of shells in the section of fuel
tanks.
It is necessary, on the basis of computer analysis and existing theories, to determine the stresses in the
waffle shell that cause internal deformations that result in a general shape error, and to derive patterns
under which external influence on the geometry of the mold at the time of bending is possible.
The proposed campaign will make it possible to determine auxiliary technological elements for setting
standard rolling equipment for defective rolling of wafer shells of missile fuel tanks with various
geometric versions of reinforcements. It, in turn, will increase the efficiency of forming shells and the
quality of welds when they are welded |
