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.

E 7018-1 is acceptable up to -46 degree but selection E 6010 is not suitable for LTCS ! As per which clause it is selected for LTCS ?

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?Shashank Vagal
