I think if you are using electrode for NACE Requirement Qualification there is no need to weld of test coupon from any specfic electrode only there is requirement of hardness in NACE
Check hardness value in test certificate of that electrode to be use. In as weld condition hardness value should not be more than 237 BHN.

Dear Experts,Could anyone advise me about the following:I need to qualify some SMAW electrodes based on NACE, e.g. E7018 or E8018-G. Which type of test coupon and test procedure shall use for this purpose?--I read NACE MR0175, TM0177, TM0284 but in those standards there is no specific requirements related to welding consumables.Regards--
