E7018 vs E8018

E8018 is a welding rod as per AWS A5.5 for low alloy steel welding while E7018 is as per AWS A5.1 for mild steel and carbon steel welding.

E8018-XX has -XX supplement classification to cover wide range of low-alloy welding electrodes. Example of such rod are: E8018-B2 ( for Cr-Mo steel), E8018-C1 (For Nickel Steel), E8018-D2 (For Mn-Mo Steel), etc.

There is no electrode only having classification as E8018 is available.

E7018 vs ER70S-6

E7018 and ER70S-6 are both having same weld deposit mechanical (tensile, yield & toughness) properties and chemical composition.

The main difference is type of welding process they are used- E7018 is for Stick Welding (SMAW) while ER70S-6 is used for MIG-MAG (GMAW) & TIG welding.

An external welding shielding gas is required for ER70S-6 welding while with E7018 no external shielding gas is needed.
