Re: [MW:29688] ER70S-2 and ER70S-6 (GTAW Process)

Dear All,

Request you to go through the query properly before you reply. Also do not reply if u are not clear about it. Else it will lead to confusion. 

A no is essential variable for WPS/PQR.  Irrelevant of impact requirements. A no of ER 70S-2 and ER 70S-6 will never match. Hence you need to go for new PQR.

Yes you can.  However, if your WPS states that the filler metal per essential variable QW-404.5, will meet the Table QW-422 A-No. 1 chemistry limits, you will have to note that the Mn and Si must be 1.60 and 1.0 or less respectively.  You need to do incorporate this restriction as the SFA classification permits ER70-S6 to exceed the A-No. 1 limits

Dear All,

 

My PQR is qualified with ER70S-2.

 

Can I use ( Mention) ER70S-6 in WPS.

 

Regards

Kiran
