DOI:https://doi.org/10.2172/5838142· OSTI ID:5838142
An autogeneous butt weld using the internal bore weld process is described. The weld is designed for the CRBR steam generator tubes to tubesheets which are fabricated of 2 1/2 Cr-1 Mo low alloy ferritic steel. As a precaution against in-service weld cracking, each weld is heat treated prior to inspection. (FS)
