Dear Sir,
Normally E 7010 is suitable for root welding as it will give good penetration. Hot pass fill up you may use E7018. When PQR required impact test your electrode shall be impact tested higher than the required temperature. It is only assumption as you have not given the base metal quality grade etc.
Thanking You,
Honesty is the best Policy
With Warm Regards,

You are not clear..
Which electride you used for root run ?
What is the job thk ?

I suggest use GTAW root & E 7018 fill.
