A few questions we will need to help you along:
1. Are you using AWS D1.1?
2. Was your test coupon a CJP? or PJP?
3. Pipe diameter and thickness used in WPS qualification test?
In D1.1, there is a very important "supplementary" variable in Table 4.6. Base Metal 2) -- Minimum thickness qualified is 5/8" (16mm) whichever is less, except if T is less than 1/4" (6mm), then the minimum thickness qualified is 1/8" (3mm).

Huisman, I do not understand what 108*8/13 means. 108mm OD X 8mm Wall Thickness, but 13mm??
