Abstract Details

1975, Master of Science, Ohio State University, Welding Engineering.
An investigation was initiated to study the effects of substituting a low carbon steel guide tube for a stainless steel guide tube in the consumable guide method of electroslag welding austenitic stainless steel. This thesis investigates the effects of the carbon steel guide tube on strength, ductility, microstructure and corrosion resistance of the stainless steel electroslag welds. In addition, a ferrite analysis as well as an evaluation of commercially available electroslag fluxes were performed. This study revealed that the tensile strength and the percent elongation obtained with the carbon steel guide tube were as adequate as those obtained with the stainless steel guide. The chemical composition of the welds made with the carbon steel guides were equal to those made with the stainless guide except that the carbon steel guide welds had an average of 1% less chromium. However, this deficiency in chromium still met the minimum of 18% chromium required for Type 304 austenitic stainless steel. Intergranular corrosion tests have shown that no severe sensitization is present in the weld metal or the base metal. The electroslag weldments were analyzed for ferrite content with the Magne-Gage and Ferrite Scope. The results of these tests are shown in Appendices B and C. The electroslag weldments which utilized a carbon steel guide tube and Type 308 filler metal had an average ferrite number of 3.5. The electroslag weldment made with the same filler metal but a stainless steel guide tube had a ferrite number of 5.3. The Arcos BV flux proved to be the best for electroslag welding austenitic stainless steel. In summary, this study concluded that a carbon steel guide can be used in a stainless steel electroslag weld without detrimental effects on chemical composition, strength, ductility, corrosion resistance and ferrite formation.
