[MW:26403] Stringer/weave bead in robotic welding machine

Dear all,
I am preparing a WPS for robotic welding of a pipe of dia 12". Welding process is GTAW + GMAW. As per QW 410.1 in ASME sec IX stringer/weave bead is there only for manual/ semiautomatic welding. During PQT I have done weaving on all the layers other than capping. Then what should I write in PQR for 410.1 ??

Also what does oscillation mean in robotic welding? Is there any limit for oscillation?

Regards,
Aby K Jose
