Up Topic Welding Industry / Inspection & Qualification / D1.1 Clause 7

Am I given to understand correctly that Clause 7 is written in a manner that section 7.9 is simply a way of not having to perform pretesting each and every day/shift, whereas without this 'prequalification' you are required to perform pretesting?
And therefore, there is no actual requirement for procedure qualification other than the pretesting?

I'll put in my two cents as it's just my interpretation and I'll probably be corrected here shortly.

I feel 7.9 is a way for manufactures to stay honest to table 7.1 and 7.3. They have to make sure that the product is meeting the minimum standard.

In a shop environment, I shoot studs per 7.6.6 to create a WPS and welder PQR if needed. After that as far as production I resort to 7.7 which does have stipulations as far as start of shift requirements.

That is just my understanding and interpretation, I may have been doing a lot of extra work this whole time, but I've always been comfortable with it. Testing two studs at the start of shift usually doesn't take that long.

I went back and did some more reading. I had completely misunderstood.
7.2.4 puts the onus on the manufacturer. I am attempting to acquire the data.
And I would agree on 7.6.6 and 7.7. That's the way I read it too.
