My Contractor insits on-
Primary Code is ASME IX only.
My understanding
Design/Construction Codes requirements shall always take precedence over ASME IX requirements.

Dear Sir/Madam,
I have a doubt in interpretation of welder qualification period.
In my case, a welder is qualified by conducting qualification test during Jan,2015 as per ASME Sec-9. Tests are OK.
So, his period of qualification is Jan,2016 to June,2016. During this period, he performed a welding on job (Production weld) on March,2015. After that he didn't performed any weld regarding that initial qualification.
Now(June 2015), a welding engineer notices that his qualification going to expire. And the Engineer plans to extent his qualification by production weld, he finds out the welder performed the welding on March, 2015.
My question is,
1. The welder qualification renewal is from March,2015 to August,2015
[OR]
2.The welder qualification renewal is from June,2015 to Dec,2015.
