GRoberts,
Thanks for keeping this thread alive :-) I would really like to figure this out.....
I'm still not sure about how to handle a PQR where they only tested one diameter wire...say a .063", but want to write a WPS for .035" wire, or some other smaller diameter....the amperage/voltage/travel speed/etc will most likely be out of the original ranges of the PQR that was tested with .063" wire. Even if you could stay within those ranges....it probably wouldn't be optimal/productive for the smaller sizes.
I'm thinking you will end up needing additional PQRs to write the WPSs for the smaller diameters anyway to stay within a productive set of parameters that would be optimal for those smaller sizes.
Do you agree with this thinking?
EDIT: Wait...I re-read your reply....are you thinking the code is saying that if you used muliple sized wires from the root out to the cap, then you would have to stay within the ranges as tested in the PQR? That makes sense.
But ......, I was thinking the original poster was asking about testing with one diameter from the root out to the cap, but wanting to write WPSs from that PQR to weld with smaller diameter wires.....
