Re: [MW:10106] Can I use E 7018 in Pipe root runs? Wats the disadvantages?

Hi Shri,

There are some importent information missing like grade of material and thickness,
E7018 electrode contains iron powder in the flux,With the root run a fast cooling electrode is desirable (that is why cellulosic electrodes are so commonly used)and the E7018 is not a fast cooling electrode.

I would suggest to go for E7010 for root runs which can be used for higher API grades, having said that you should also know that E7010 may induce hydrogen into the weld and cause cold cracking if Preheat not done. also E6010 is widely used for Pipe root runs.
