QW 403.6
QW 403.6
(OP)
Hi, uptill now I was under the impression that qualifying a PQR on 6mm T qualifues from 3mm to 12 as per qw 403.6.and there are few interpretations in support with this.
But in ASME IX 2015 addition there is an interpretation IX-15-03
Question:A welding procedure with impact testing was qualified using a test coupon of 6mmm. Does this qualify for 3mm to 12mm thicknes, since 6mm thickness is less than 1/4 inch (6.35mm)?
Reply: No; see Nonmandatory Appendix G.
Now this is something confusing. Please help
