[MW:3360] Re: Heat Input

With E 6010 PQR will always pass becoz during preparation of impact test specimen max. weld metal deposited by E 6010 in root is going to be  removed.
but in actual service situation is different so i would like to know As per which clause E 6010 selected for LTCS ?
regards

E6010 will support up to -29 degree celcius only and used in pipe line root application. But if the PQR passes the impact you can use it with batch restriction.

Adi, Heat input is a guideline for subsequent welding. The yardstick is the average  value as obtained from your PQR. Your production welding should not exceed PQR HI values. By the way, is 6010, 7018-1 Ok for LTCS?  What is the working temp?
