question about weldability of API 5L X52 vs API 5L Gr B
(OP)
Good morning,
want to ask the following: What considerations should be taken into account for welding pipelines API 5L X52 (OD Ø6,625", SCH STD e=0,280) with API 5L Grade B (OD Ø6,625", SCH STD e=0,280)?
if there is a post with the same question or similar, please send me the URL.
Regards.
LV

Per API 1104 5.4.2.2 "When welding materials of two separate material groups, the
procedure for the higher strength group shall be used".
Also, per API 1104 5.3.2.2 "The materials to which the procedure applies shall be identified. API Spec 5L pipe, as well as materials that conform to acceptable ASTM specifications, may be grouped (see 5.4.2.2), provided that the qualification test is made on the material with the highest specified minimum yield strength in the group."

if you have tow different base material you can use the WPS of material who has the higher yield strength WPS
good chance
