Welding rods, or welding electrodes, remain key components in welding. Electricity is run through a welding rod, creating an arc of live electricity at its tip and allowing for welding to take place. A variety of welding rods, including 6011 and 7018 rods, offer different features.

Tensile Strength

Metal Web News claims that 6011 welding rods are capable of producing welds that feature a 60,000 psi minimal tensile strength. The 7018 welding rods produce stronger welds that feature minimal tensile strengths of 70,000 psi.


Most welding rods are manufactured with a protective outer coating. According to Welding Tips & Tricks, 6011 welding rods are manufactured with an outer coating made of high cellulose sodium, compared to low hydrogen iron powder for 7018 welding rods.

Other Differences

The 6011 welding rod is engineered for everyday, general welding applications. The 7018 welding rod is employed for applications that call for crack-resistant welds and exceptional weld quality. The 6011 rods are manufactured for operation under direct currents, while 7018 rods can be run under direct or alternating currents.
