Qualifications for to butt small bore pipe to plate 3

[dhfrye]

If a welder is certified for B-U2a joint in the 3G and 4G position is he also qualified to fillet weld small bore pipe to plate?

Don't know for sure what code you are working with, but here is the passages from AWS D1.5 Bridge Welding Code.

5.22.1.2 3G (Vertical) Qualification in the 3G (vertical) position shall qualify for flat, horizontal, and vertical position groove welding of plat and structural shapes; and flat, horizontal, and vertical position fillet welding of plate and structural shapes.

5.22.1.4 4G (Overhead) Qualification in the 4G (overhead) position shall qualify for flat, and overhead position groove welding of plat and structural shapes; and flat, and overhead position fillet welding of plate and structural shapes.

dhfrye....pipe qualification allows you to weld plate but not the other way around. For this application, must be pipe qualified.

If you are using AWS D1.1 look at table 4.8. If you qualify for groove welds,you are qualified to fillet weld . Paragraph 4.18.1.1 Refers you to the above table. You can view the table

. This is from 98 code

pipewelder1999 is correct. I missed the "fillet" notation.
In 2004 code, the table is 4.10
