Tracking RT failures

[Cloya14]

All,

Ive recently been tasked to develop a system to track and record RT failures in our pressure vessel welding shop. Currently our quality team believes since we are not recording this therefore it is leading us to believe we are being too lienient on x-ray failure percentages on a per welder basis. My biggest issue is we have some vessels that are harder to fit and weld than others, for example a 6' sch. 40 steel three foot long vessel is easier than a 52" sch. 80 stainless vessel. So does a failure in the steel pipe constitute a "bigger" checkmark than the stainless vessel that is presumably harder to fit and weld? Any ideas to what others are doing in their shops to help track this would be great. Thanks everyone in advance.

We track failures vs. total number of film shot per weld. This gives us a success rate for each weld and a monthly average for each welder and a composite total. Some track it by inches, but if I have a reject I have to reshoot the whole shot not just the inch(s) rejected. I run it on a spreadsheet and also get a year to date average.

That actually sounds like a great idea. Could you PM me an example spreadsheet you use at your workplace?
