Abstract:

Stress corrosion fracture toughness measurements were made on the welds of 2 in. thick HY-140 material intended for use in the DSRV-2. The welds were of the standard TIG type using the same joining practice as that for the pressure spheres. At this level of fracture toughness critical flaw sizes are of sufficient size that they should be easily detected during non-destructive inspection.
