Re: [MW:30871] Control t 8/5 during job welding for non PWHT joints.

Dear Karan,

You should continuously record the temperature during welding of the PQR test coupon.
It's better to have thermometers linked to a temperature recorder so you could have a reliable and permanent record of these temperature readings; all the parties sign it and you can easily calculate the calculate T8/5 for future use.

Dear Experts,

Please clarify to me , how to control t 8/5 during job welding for non PWHT joints ?

I have calculated 3D and 2D Heat flow, but the client is asking how to control t8/5 in production weld ( method to measure production welding( on job ).
 
 Thanks in advance.

Regards,
