UCS 56 and Sec IX
UCS 56 and Sec IX
(OP)
In ASME Sec VIII Div 1, UCS 56 alternative longer soak time at lower temperature provision is given(Indicating that they are equivalent, although not explicitly). If a manufacturer opts to use this provision then is it necessary for the maufacturer to Perform PQT with longer soaking at lower temperature to support his WPS or is it OK if the normal cycle PQT would supports his WPS.

The black holes of nature are the most perfect macroscopic objects there are in the universe: the only elements in their construction are our concepts of space and time.

RE: UCS 56 and Sec IX
I agree with GRoberts post as stated too. As per UCS 67, if base material requires impact testing, the weld metal requires impact testing too. I was just trying to break the monotony by pulling GRobert's leg a bit. A testimony to the fact that I agree with the appropriateness of GRoberts answer is a star for his answer.

RE: UCS 56 and Sec IX
I maybe wrong (again), but if you refer to UG-84(f),which deals with impact testing of welds, it cross-refers to UCS-85.
Needless to say, I agree with GRoberts.
RE: UCS 56 and Sec IX
If i recollect properly(Sec IX is not readily available with me) Qw 407.2 is applicable even if the material (and or the weld)does not require Impact. In which case how is it ok to give prefrential treatment to material which does not require impact. As such ASME SEC VIII div 1 has (Atleast in principle) indicated the equivalence of lower temp soak for longer duration.
