E7018 or E7014
E7018 or E7014
(OP)
I am working on a small structural project and the welding contractor is looking at using E7014 instead of E7018. I have never used E7014 on anything significant. I know that it makes a very smooth weld but I have to say I am much more comfortable with them using E7018. Am I being overly cautious or should I just go with it?
Thanks

The only thing to watch out for is lamellar tearing. The 14 electrode will have much higher hydrogen levels. Depending on your joint configuration and steel properties you could run into this problem. Make sure the advantages of using a 14 are worth it.
I've seen this happen to an entire building during erection. It was not easy, or cheap, to fix.
