CHAPTER 6 - Materials of
construction and quality control
6.5 Welding of metallic materials and non-destructive testing
6.5.3 Welding procedure tests for cargo tanks and process pressure
vessels
1 Paragraph 6.5.3.5.1 is replaced by the following:
-
".1 tensile tests: cross-weld tensile strength shall not be less
than the specified minimum tensile strength for the appropriate parent
materials. For materials such as aluminium alloys, reference shall be made
to 4.18.1.3 with regard to the requirements for weld metal strength of
under-matched welds (where the weld metal has a lower tensile strength than
the parent metal). In every case, the position of fracture shall be recorded
for information;"
