Dear all ,
I hope the detail which I am going to ask may be familiar to all,
The Query is for GTAW –Carbon Steel welding some time we will use ER-70S-6 but it is not having valid A-Number as per ASME Section IX. But in ASME Section II –C they given this electrode chemical composition for one range but in ASME Section IX they have some limitations for A-Numbers. Why this happens it all under ASME Code. Can anyone explain. How to solve this problem. For example some company bought ER-70S-6 in huge amount what they will do. Please find a solution?????????????
