Welding Different Grades of Steel in API 650
Welding Different Grades of Steel in API 650
(OP)
What are the rules and/or guidelines in API 650 of the shell plate of a storage tank having different grades of steel? Is there anywhere where it explicitly allows or does not allow this? We want to use a slightly higher grade on the lower courses and then a higher grade steel towards the top of the tank and cannot find any guidelines in the standard.
Thanks in advance
