    Hi, I was wondering if someone could help clarify the range for welding positions qualified in AWS D1.1 – Table 4.10 (p147)?

    Does a 3G and 4G (Plate Butt) also qualify a welder to weld a 5F?

    Seems to be restricted by dihedral angle only?

    Butts in pipe have to be larger than 600mm in diameter.

    But is a 5F on 80mm pipe OK?

    Cheers

    IG,
    Under Production Pipe Welding Qualified – Fillet it lists “All (h)”
    h concerns the dihedral angles – if the 600 mm restriction was applicable it would have shown a (c).
    Answer to your question is yes,
    Regards,
