American Welding Society Forum
I have an SMAW WPS that specifies E8018-C3 electrodes for the fill material. Could I substitute E8018-C2 for welder test qualification? I want to test the welder today and I don't have any E8018-C3 electrodes on site today. We will be using the E8018-C3 electrodes for all production welding.
They are both included in AWS A5.5 and they are both F4, so go for it.
