[MW:985] Re: HAZ

Dear Mahuri,

Actually length of HAZ cannot be specified so easily. In any case you
can follow the link to have just an idea for it.

http://www.esabna.com/us/en/education/knowledge/qa/How-does-welding-affect-the-HAZ-of-the-weld.cfm

Regarding your 2nd question I can tell that the Code name itself
identifiy the difference.
API 650 is for the "Welded Steel Tanks for Oil Storage" and API 620 is
for the "Design and Construction of Large, Welded, Low-Pressure
Storage Tanks".

Regards,

R. Bose
