RE: [MW:13249] IMPACT TEST -SUB SIZE

Hi,

 

We need to perform the impact test as per Client Welding spec for each process. This is the reason I have to go with subsize.

 

With Kind Regards,

 

S.Elumalai.

Hi Aas such   there is no need of sub size You can have single size of 9 or 8.5mm x 10mm Impact specimen as it covers both process   Regards   Hegde --- On Wed, 21/12/11, Sundaram Elumalai <Elumalai.Sundaram@starfab.com.sa> wrote: From: Sundaram Elumalai <Elumalai.Sundaram@starfab.com.sa> Subject: [MW:13243] IMPACT TEST -SUB SIZE To: materials-welding@googlegroups.com Date: Wednesday, 21 December, 2011, 9:45 AM Hi,   Now we are qualifying two new PQR for new project for less base metal thick. (9mm). Code AWS D1.1   ROOT / HOT Pass              -GTAW (deposited 4mm) Fill/Cap                                - SMAW (deposited 5mm)   We need to perform the impact test as per Client Welding spec for each process. In this case, we have to go for Sub size with temperature reduction.   Client Welding spec requirement is minimum - 29 °C.    If I go with 10x5mm sub size, I need to reduce 11.1 °C  and test to be done at -40.1°C. (  -29 -11.1)  Then Joule value will considered as per ASTM 370,16 J from the below second table.   Is it correct ?   With Kind Regards,   S.Elumalai. ****************************************************************************************** CONFIDENTIALITY NOTICE This e-mail and any attachment are confidential and may be privileged or otherwise protected from disclosure.
