I am just adding one thing. Suffix G means general and it can be any combination. If anybody wants to purchase Electrode/Filler with suffix G,then he needs to specify the correct combination to avoid any last minute confusion.

So always check the catalogue before proceeding with PQR or production.This caused the company a lot of trouble since these are two different filler metals with different properties. Ni additions are suitable for low temp service but Cr/Mo additions improves high temp service properties (the application was a gas turbine exhaust - high temp service).Dear Mr. Rezazade:Be careful when using filler metals with a "G" suffix since they may have any combination of alloying elements and only by referring to manufacturer catalogue you can find out which alloying element(s) they have used.
Once I remember that a company qualified a WPS with E8018-G (that later I found it had Cr/Mo additions) and during production their procurement officer purchased another E8018-G (that later I found it had Nickel additions).

Dear sirQW-404.12 is supplementary essential variable and when impact test required in your WPS (or production) according to construction code, you need to consider it as essential variable..so changing the brand of G suffix electrode is not permitted in WPS without re qualification of PQR with new brand of electrode. (when impact test required)
در سهشنبه 9 فوریهٔ 2010، ساعت 5:10:20 (UTC+3:30)، yan نوشته:Hi Gentlement,We have many qualified WPS/PQR (GTAW process) using filler metal with a "G" suffix such as ER-70S-G and qualified base on ASME Section IX ( using previous ASME IX Ed. 2004/Ed. 2007) . In QW-404 / Filler Metals), para QW-404.12 state that change classification is NON ESSENTIAL VARIABLE. But in ASME IX Ed. 2007 addendum 2008, in the same QW-404.12 state that change in classification is SUPPLEMENTARY ESSENTIAL VARIABLE ( a filler metal with a" G" suffix)Our question is whether this existing WPS/PQR need re-qualification (change from NON ESSENTIAL VAR to SUPPLEMENTARY ESSENTIAL VAR)?Great thank to get sharing accordingly.Regards,YanPowered by Telkomsel BlackBerry®
