Re: [MW:3970] welding procedure for the material at - 30degree C

Dear Ellik,

 

Usage of same PQR depends upon your code of fabrication, Parent & consumable Material used for qualification & thickness of materials.

 

Some fabrication code does allow to use the same PQR without further impact testing as long the material (parent & consumable) itself  qualified to use (upto certain lower temperature).

Subject: [MW:3965] welding procedure for the material at - 30degree C

Dear Friends,
 
I have a welding to do on the material where the service temperature is -30 degree C. I have got a welding procedure which charpy V test was carried out at -20 degree C. can I use this procedure for welding of the material which the service temperature is -30 degree C?
 
regards,
Elilk.
