Embodiment Construction
[0021] It can be seen from the background technology that the traditional welding process of the bottom of the carrier rocket tank in my country is TIG welding, but the quality of this welding process is poor. Friction stir welding can improve the welding quality, but friction stir welding needs to solve the internal problem of support.
[0022] The inventors have conducted research on the above problems, and in the present invention provide a friction stir welding welding tensioning device for the girth seam of the carrier rocket tank. Hereinafter, the present invention will be described in more detail. However, this invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.
