I have a doubt pertaining to the bevel ends preparation as per ASME B16.25.
While defining the type of end preparation for butt welding as per ASME B16.25, say for e.g. for nominal wall thickness greater than 25 mm GTAW root pass, on what basis do we decide the type of the bevelled ends in Fig.6. i.e. is it type A or Type B?
Apart from the wall thickness what are the other parameters to be considered to select type of bevel ends from Fig.2(a), Fig,3(b)...etc. from ASME B 16.25. Is the base material also a parameter which governs for the selection of the type of bevel end preparation for butt welding?
I request if any of you could guide me. Thanking you all in advance,
Regards,
Harsha Bhat.
