Re: [MW:11495] Minimun thickness requirement to carryout PWHT for CS

Hi venkateswaran

 

1) PWHT as per UCS-56 is mandatory for welded joints over 38 mm nominal thickness.

2)  for welded joints of  nominal thickness over 32 mm through 38 mm, PWHT is not required if  preheat is applied at a
minimum temperature of 95 degree celcius during welding.

 

Please go through all the notes, in UCS-56 for exceptions.

 

Thanks
