NAME OF PERSON:
Rick Dill, Metallurgical Consultants
SUBJECT: Welding Requirements of Shop Fabrication
DIGEST: Mr. Dill's shop is making up fabricated assemblies by ASME Sec. VIII rules and
wondered if a weld with a crack in the strings bead could be repaired. Repair is allowed by
ASME Sec. VIII but not be Part 192. I told him my opinion was that it could not be repaired, but
would have to be cut out to comply with Part 192. The only welds which need not comply with
Subpart E are welds which occur during the manufacture of steel pipe or steel pipeline
components. I said I would not consider fabricated assemblies to be a component. A component
would be such items as fabricated valves.
Mr. Dill agreed and said they will petition OPS to revise the rules to except shop welding done
under ASME Sec. VIII. I agreed that was a deficiency here and urged him to follow through with
the petition.
