Hello
I have only done a few welding procedures to ASME IX.
I need to do one now for ASTM A519 1020 CW. The base metal grouping is a P-no. 1 Group 2. No impacts, no hardness, etc.
My questions are:
1) why is there no min. specified strength in ASME Section IX for this material?
2) I have a PQR / WPS now for P1 material, can I say that my A519 1020 CW is covered under my old PQR / WPS?
3) I have about 6 MTR, one of my MTR just has 1020 CW with no specification on it. It could be AISI, SAE, ASTM, etc., to me it must have a specification or it must be treated as an unlisted material? yes or no.
Thanks
