AI Technical Summary
Existing technologies have difficulties in the longitudinal welding of the rocket outer body, and new welding technologies need to be developed to improve welding quality and reduce the mass of the rocket outer body.
10mm stainless steel plates are used and rolled into arc plates by a large plate rolling machine. Submerged arc welding technology is used to splice the stainless steel plates into semicircles, and then the two semicircles are butt-welded to form the outer body of the rocket.
High-quality welding of the rocket's outer body was achieved, reducing the weight of the rocket's outer body.
Abstract
Description
Technical Field
[0001] Aerospace technology field. Background Art
[0002] The rocket outer body manufacturing technology is cross-section welding technology, and longitudinal welding technology needs to be developed. Summary of the Invention
[0003] This patented technical solution is made of 10mm (or other size) stainless steel plates (or other metal plates) welded longitudinally.
[0004] Use 10mm stainless steel plates to weld a first- or second-stage rocket body with an outer arc diameter of 10m (or other dimensions) and a height of 63m (or other dimensions). First, fabricate a 21m long (or other dimensions) stainless steel plate. {According to the formula for the circumference of a circle, the circumference of the outer arc of the rocket body is 31.41593m, while the circumference of the inner arc of the rocket body is 31.3845141m.} Assuming 10 stainless steel plates are assembled, the outer width of each plate is 3.141593m, and the inner width of each plate is 3.13845141m. Fabricate 30 stainless steel plates of this specification.
[0005] Thirty stainless steel plates are rolled into arc plates with a diameter of 10m by a large plate rolling machine. The outer arc size of the arc stainless steel plate is made into 3.141593m by grinding, and the inner arc size of the arc stainless steel plate is made into 3.13845141m. In this way, five stainless steel plates are butt-jointed on the basis of prefabrication, and the five stainless steel plates are welded into a semicircle by submerged arc welding (or other welding methods). Finally, the two semicircles are welded together firmly to form a section of the outer body of the rocket.
[0006] The three sections of the rocket's outer body are then aligned longitudinally and welded together to complete the rocket's outer body. This welding technique can reduce the mass of the rocket's outer body.
