Please explain to me that What is difference between T limit & T qualified ? Many Thanks
@Hieu_Thai read in ASME IX
QW-403.6: T-limits (supplementary essential)
QW-403.8: T qualfied (essential)
Sample explaination at Welding procedure specification - GTAW (ASME IX P-Number 10H)
That means is T-limits apply to CVN, T-qualified apply to normal WPS ?
Yes, T-limits only apply when CVN required.
any specific in AWS D1.1
