Zusammenfassung:Inherent problems were experienced in manual MIG welding Saturn DSV-4 fittings to domes. Repairs, especially at weld starts and tie-offs, were frequent and costly. In order to upgrade weld quality and to further automate Saturn S-IVB production, the automatic D.C. TIG process was implemented for fitting-to-dome welding. This program was established to generate D. C. TIG process data and to develop capability for production weldings of fittings to domes. Weld tests were performed both in the laboratory and in the production shop. These tests demonstrated that the D. C. TIG process eliminated many of the difficulties associated with Manual MIG welding of fittings to domes. (Author)
