RE: [MW:4731] ER70S-3 for low temperature application

Dear Ibrahim,

 

In order to assure, each batch shall be tested for impact toughness test at MDMT in addition to test conducted during PQR qualification. In general filler metal manufacturer will satisfy the requirements of ASME Sec. II Part ‘C’. Any additional requirements shall be communicated to the manufacturer in PO itself in order to meet the testing requirements.

 

Some of the reputed manufacturers such as Lincoln, Bohler could able to meet the above requirements. Please enquire with them.

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,

 

The code is ASME SEC. VIII Div.1.

Could you clarify what is the application code? Section I, section VIII-1?

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
Muhammed Ibrahim PK
