Research achievements applicable to the production of Saturn V components are described. Leakage at the mechanical connections in high-pressure lines has been minimized or eliminated through the use of precisely flared tubes. A technique of aging or heat-treatment hardening of aluminum materials has been used to form cylindrical-tank segments and double-contoured gore segments precisely, and to remove weld distortions. The control of weld porosity has been improved as a result of research which demonstrated the close correlation between electrical energy input per inch of weld and weld porosity and metallurgical quality. Control techniques for milling by chemical etching have been developed. As a consequence, chemical milling has been used extensively for Saturn V gore segments. This report reviews manufacturing research achievements which are being used today to assist in the production of Saturn V components.
