    Hi,

    If say i welded a joint with a wps that has the parent material as grade 350, what other steel/grade's can i use this welding procedure for?
    or better yet where can i find the answer to this question in the standard?

    If the WPS has Grade 350, that is all you can weld.
    However, if the PQR was qualified on Grade 350, this allows you to weld anything from Grade 400 and below.

    See AS/NZS 1554.1:2011 Clause 4.8
