Look in ASME Section V, Article 4 or 5. The basic calibration blocks for UT are based on the base material not the welding process.
However, the UT operator should be familiar with the welding process in order to determine what type of indications to excpect.

i can tell only for the ERW pipes. N10 & N5 notches at OD & ID are used and through holes at wels seam are used.

Re: SAW and ERW pipes - standards Standards for ERW and SAW pipe seam welds are similar world wide.
The North American versions are API 5L and in Canada CSA Z-245.
A Standard Practice by ASTM is also used, ASTM E-273.
