Dear Sir,
UCS 67 (a) (2) says 'Weld made with filler metal shall be impact tested if base metal is excempted by UCS 66 and MDMT is colder than-29 deg.c and not colder than-48deg.c and welding consumable is classified by impact test at a temperature not warmer than the MDMT by the applicable SFA Specification is used.
In my case I mentioned ER 70S-3 is specified for -20 deg.C as per SFA Spec. which is warmer than the MDMT of the euipment (-46 deg C).
My query is, as stated in UCS 67 I have Impact tested the PQR at MDMT -46 and passed the test. As per the proven support of PQR can I use ER 70 S3 for -46 deg.C application without seperate batch test?.
Regards,
Muhammed Ibrahim PK

Then you will find your answer in USC-67.
If you do not have the code or you have interpretation problems let me know.

--Hi members,Please provide a suggestion for the following query.I have qualified a PQR for GTAW+SMAW with ER70S-3 & E7018-1. The PQR is impact tested at - 46 deg C at root(GTAW) and filling (SMAW) and passed (Min. 50J energy obtained).As per ASME Sec.II part C, E7018-1 will support up to - 46 Deg C, but ER70S-3 will support up to - 20 Deg.C only.Since I have proven the toughness through PQR, can I use this PQR for job with impact test requirement of - 46 Deg C, even ER70S-3 does not support for this temperature as per Sec.IIC?.
Thanks & Regards
