Hello guys,
Found this post while researching API 510 and thought I would really confuse the subject.
ASME IX - Page 1 - ASME Boiler and Pressure Vessel Code - Qualification Standard for Welding and Brazing Procedures........
ASME B31.3 - Page 1 - ASME Code for Pressure Piping, B31 - An American National Standard
AWS D1.1 - Page 1 - An American National Standard - Structural Welding Code - Steel
API 650 - Page 1 - API Standard 650 - No mention of code.
So it appears that there is no difference with ASME and AWS regarding codes/standards but API uses standards.
There you are, clear as mud.
Regards,
Shane
