Dear friend Generally mechanical tests prepared from a radiography accepted test assembly which is welded in predefined conditions. Such tests are tensile (all weld meta), impact and in few cases transverse tensile, hardness and bend test. Also chemical analysis from weld metal or rod may be added. (for details you have to refer to the related std.) About the quality, all approved producers shall satisfy minimum requirements indicated by standards. But the subject is how much they can be overqualified. They work on the usability of they products and improving the consuming time and economical issues. So the producer is very important and some specifications require re-qualification in case of changing welding consumables producers.

Hi Ezzat, In simple english, When the client calls for for WPS with Charpy Impact, then the group no. comes into picture,  In other words, if you have a PQR with a particular P No and Group No., you can generate any no of wps from that PQR provided that the material that is going to be listed in the WPS falls within the P No. (provided there is no CVN requiremnt). You dont have to look at the Group no. at all. BUT When there is a CVN requirement, you can use the PQR to develop a WPS ONLY for the particular P No. and Group No. You have to see that the material in construction should belong to the same P No. and Group No.  On Wednesday, 30 October 2013, 15:39, zakir ali <zs00765@rediffmail.com> wrote: It does not required re qualification.
