Various Rev isions t oSection IX regarding Terms such as “…omission of inert back ing gas…”
Various rev isions to Section IX are being made to no longer require t he requalification of a welder whenan inert gas
back ing is not used. QW-408.8 is anessential variable for performanc e qualificationfor welders qualifying for GMA W/
FCA W, GTA W, and PAW. By strict application of this rule, a welder who qualifies for GTA W using argonas the back ing gas
must requalify if he want s to weld using a react iv e gas mixt ure such as 90 % argon/10 % nitrogen, which is c ommonly
used in Europe. This requirement to requalify is not just ified in t hese cases because onc e a welder has prov ed he has
the sk ill to deposit sound weldmetal welding in t he presenc e of back ing gas pressure, the gas c omposit ionis no
longer important.

Add a New Mandat or y Appendix Cov ering Laminat es with LoadSharing Metallic Shells for High
Pressure Ser v ic e
This new appendix was added for new requirements for laminates with load sharing metallic shells for high pressure
serv ic e. This A ppendix defines t he requirements for the materials, desig n, fabrication, qualification, ex amination and
t esting of laminates to be applied as part of t he fabricat ion of a Sect ion VIII, Division3 c omposite pressure v essel. The
c omplet ed v essels are definedas c omposit e reinforc edpressure v essels for storage of fluids at high pressure. This
appendix inc orporates many of the requirement s t hat were c ontained in Section VIII, Div ision 3 and shall only be used
per Sect ion VIII, Division 3. Additionally, t he lat est ASTM standard on ac oust ic emissions t est ing is inc orporat ed.
Add a New Nonmandat or y Appendix on Micromechanics
This appendix add micromechanics as an alternat iv e method t o testing, for det ermining elastic properties of a
lamina. This nonmandat ory appendix c ontains the equat ions that can be used t o predict elastic c onstant s for bot ha
unidirect ional lamina andfor a randomly dist ributed reinforc ed lamina. Determinat ion of the elastic c onstants using
micromechanics would be permissible as analternat iv e to determinat ion v ia t est ing per RT-7. This proposal also
includes the changes required t o various parag raphs t o permit the use of micromechanics t o determine the elastic
c onstant s as an alternate t ot esting per RT-7.
