you can weld two dissimilar thick pipes and fittings by making proper transition of higher thickness to lower thickness.

Transition slope should be 1:3. Please refer figure UW-13.1 of ASME VIII DIV 1 for better understanding.

Hello everyone 

im asking for any information about the maximal thickness to weld between two different wall thickness  from  B31.3 or b.16.25 

in my case we want to weld  12'' THICKNESS 25.4 WITH 12.7 ITS POSSIBLE RE-SCHDULING THE INTERNAL THICKNESS FOR 12MM OR THER IS A MAXIMUM THICKNESS LIMITS 

BEST REGARDS
