Title: Weldability testing of alloy 800

Technical Report ·
DOI:https://doi.org/10.2172/6936622· OSTI ID:6936622

The weldability of various heats of alloy 800 was compared by the Tigamajig hot-cracking test. This testing was conducted to determine if the test could rank the relative hot-cracking tendencies of the various heats and therefore provide a measure of weldability for future alloy 800 heats before their being assigned to nuclear component fabrication. The test accurately detected a heat that had exhibited hot-cracking in the heat-affected zone of actual weldments. Neither this work nor that of other investigators has been able to specify a chemical analysis for alloy 800 that will ''always'' be weldable. This test can, however, be used to provide a relative measure of weldability for critical applications.
