Dear Experts, I have Qualified PQR with below deatils Material: Titanium Process: GTAW Heat treatment done twice one is for stress relieving (600deg.C, 1hr soaking, furnace cooling) & other is for Oxidation( 750deg.C, 3hrs soaking, furnace cooling) on same PQR test cupon as per ASME sec.IX Now my question is, can i write two WPS with separate HT's by having back up of above PQR as one is with stress relieving & other is with Oxidation. Request to send me the reply at the earliest with some back up like referance documents if any Regards Prasu -- To post to this group, send email to materials-welding@googlegroups.com To unsubscribe from this group, send email to materials-welding+unsubscribe@googlegroups.com For more options, visit this group's bolg at http://materials-welding.blogspot.com/http://www.linkedin.com/groups/MaterialsWelding-122787?home=&gid=122787&trk=anet_ug_hm The views expressed/exchnaged in this group are members personel views and meant for educational purposes only, Users must take their own decisions w.r.t. applicable code/standard/contract documents.
