Re: [MW:13735] For expiration of welders for WPQ

1. You need to requalify if welder if he has not welded with the process qualified during the period of 6 month.
 
2. Continuty of welder must be demonstrated by keeping records of  weldment made by a welder with the process qualified. This is generally supported by NDE (RT) records of the satisfactorily made weldments by the welder.

Dear Experts,

I have confusion about validity for the welder qualification.

As per ASME Sec-IX, QW-322, When welder has not welded withe process
during the period of 6 months or more his qualification for that
process shall expire unless within 6 months period prior to his
expiration of qualification.

i have doubt that if welder is doing welding for particular process
since 1 yr under my supervision, the will i need some renewal?

shall the welder expired or not within 6 months period if he is doing
welding for particular process:

Kindly justify this clause


Regards,

Ankit Khatri
