Greetings

Please kindly advise me whether a requalification of PQR is required when changing from ER-70S2 TO ER-70S6.

Since I have a WPS qualified with ER-70S2+E7018. However, due to the non-availability of ER-70S2 can I use ER-70S6 without qualifying for new PQR.

Hi,

its a change of classification which is a supplementary essential variables , you can use the filler as proposed and it doesn't require to requalify the PQR if there is no impact test requirements.
