As per Section IX, Weld Weaving is non essential variable for GTAW process.  As such it is based on your WPS  which was qualified and recorded . If your job is having , Notch Toughness requirement, then dont go for more weaving which will reduce toughness properties. Go with multi layers .

You won't find a specific para for weave width, other than ASME section 9, relating to your WPS that has been qualified.  Maximum weave width shall be as stated in your WPS (welding procedure).  I believe this will be true for other Standards.   Best Regards,     Jim Price | Welding Engineer, CWI Direct:  320.7463439 | Fax: 417-862-5564 jimprice@polarcorp.com           From: materials-welding@googlegroups.com [mailto:materials-welding@googlegroups.com] On Behalf Of simon lawrence Sent: Thursday, March 31, 2016 5:00 AM To: Materials & Welding Subject: [MW:24595] GTAW weld weaving   Pls confirm that Weld weaving width ,  weld weave maximum how much we can accepted in GTAW process ? -- 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 f...

Hi, As per my understanding normally they do pressure testing for each valve and may be the for the printing sake they prepared one report as all the conditions are same.
