We completed the testing over the weekend and our hardness test with full out buttering just sqeeked by 350. Our sample with a simplified temperbead (which was suggested to me, ASME technique) was 400+. With a straight fillet relying on the subsequent passes to temper I would guess it would...
hmmm...the cooling test (250 to 100) I was getting times of 11 seconds to 18 seconds. I didnt think I would be able to preheat that in any sort of reliable fashion. Maybe in the shop but in the field...
I was aiming for 350 HV10 but do recognize that we can be somewhat higher since the rod...
In this case yes. The client requires a section IX WPS and the conditions will require a temper bead to achieve the acceptable hardness values. The material is 516, 3/4" WT, 0.49 CE (ASME), and water as cooling medium. Temperature is going to be around 5 Deg.C day of the work. My issue...
We are qualifying a hot tap procedure to section IX. What has been the approach to get around the thickness range limitation of fluid backing and >T in 290?
