hi
when i wanna make sample of butt joint and weld it groove weld with weld prep ( with angle 45 , root face= 2 mm and root opening = 1.2 mm )
is it supposed to make backing weld first then weld the groove weld OR i can just weld the groove only without backing ??
this sample will be sent to the lab to make X-Ray test and make tension test also
this sample for PQR  for some project and i wanna test it to approve the gas , wire and  operating parameter

In our shop we would weld the groove approximately halfway out, then back-gouge and weld the back side, then finish welding the groove on the front side. We weld to AWS D1.1. Hope this helps!

It would be helpful to tell us what welding standard applies.
