A STUDY OF INCONEL WELDING FOR NAVAL NUCLEAR POWER PLANT SERVICE
A study has been made of the weldability of Inconel with commercially available Inconel-type filler metals. The investigation included the welding and evaluation of structural welds, weld overlays, and the response of weld deposits to postweld thermal treatments. All the filler metals studied were found to be capable of producing welds meeting the current naval nuclear standards. However, all the welding processes and filler metals studied present problems or difficulties which limit their application Several difficulties may be inherent to the filler metals and are recommended for further study. These difficulties are the fissuring tendency of all Inconel-type filler metals and the precipitation-hardening characteristics of the A wire weld deposit. The Inconel- type filler metals are more difficult to use than are the 300 series stainless steels. Vendors who attempt to use the Inconel-type filler metals as they do the 300 series stainless steels may fail to obtain nuclear quality weldments. (auth)
