Preferential weld corrosion shall be assessed by - ✔✔The inspector
According to API 510 the inspector in consultation with whom, should determine when it is necessary
to remove deposits or linings to perform adequate inspection - ✔✔The corrosion specialist
For equipment not designed for entrance by personnel - ✔✔Inspection ports shall be opened
for examination of surfaces
When developing an inspection plan for vessels that operate above 750 degrees - ✔✔A
corrosion specialists shall be consulted
How does a welder get more amperage - ✔✔Increase the amperage

maintained
What are indications - ✔✔A response or evidence resulting from the application of NDE
What is the minimum design metal temperature - ✔✔The lowest temperature at which a significant
load can be applied to a pressure vessel per the construction code
